+ This uses XORG_CHANGELOG macro to properly work with the "git-log"

+ Mark Xalloc, Xrealloc, and Xfree as weak symbols.
+
+ Maybe a _X_WEAK macro could be added to <X11/Xfuncproto.h>, but that
+ could actually encourage use of __attribute__((weak)), what is not
+ intended.
+ This change uses the same semantics used in libXfont to declare
+ weak symbols that are overridden by the ones defined in the X Server.

+ Separated Intel drivers from default DriDrivers to avoid building them on
+ IA64 (Egbert Eich).
+ Fixed wrong function prototype (Egbert Eich).
+ Don't test for generic VGA on IA64 (Egbert Eich).
+ Fixed a segfault when accessing a structure before verifying the pointer
+ exists (Egbert Eich).
+ Added a showcache option for debugging (Egbert Eich).
+ Increase default video RAM size to 16MB when DRI is enabled and more than
+ 128MB are available (Egbert Eich). Fixed lockups during mode switch.
+ Problem was introduced when attempting to copy the behavior during
+ LeaveVT()/EnterVT() but but forgetting to call I810DRILeave() before
+ I810DRIEnter(). The entire DRILeave()/Enter() scenario has been
+ commented out as it didn't seem to be necessary (Egbert Eich).
+ Fix TweakMemorySize() (tested with i855/i865) (Egbert Eich).
+ increased MAX_DEVICES to 128 (Egbert Eich).
+ Use OS provided PCI config space access as default method (Egbert Eich).
+ Added support for Linux 2.6 proc file format.
+ Fixed unaligned accesses to pieces of the VBE info block. VESA did not
+ align elements to size (Egbert Eich).

+Quick Guide To Patching This Package For The Impatient
+------------------------------------------------------
+
+1. Make sure you have quilt installed
+2. Unpack the package as usual with "dpkg-source -x"
+3. Run the "patch" target in debian/rules
+4. Create a new patch with "quilt new" (see quilt(1))
+5. Edit all the files you want to include in the patch with "quilt edit"
+ (see quilt(1)).
+6. Write the patch with "quilt refresh" (see quilt(1))
+7. Run the "clean" target in debian/rules
+
+Alternatively, instead of using quilt directly, you can drop the patch in to
+debian/patches and add the name of the patch to debian/patches/series.
+
+------------------------------------
+Guide To The X Strike Force Packages
+------------------------------------
+
+The X Strike Force team maintains X packages in git repositories on
+git.debian.org in the pkg-xorg subdirectory. Most upstream packages
+are actually maintained in git repositories as well, so they often
+just need to be pulled into git.debian.org in a "upstream-*" branch.
+Otherwise, the upstream sources are manually installed in the Debian
+git repository.
+
+The .orig.tar.gz upstream source file could be generated this
+"upstream-*" branch in the Debian git repository but it is actually
+copied from upstream tarballs directly.
+
+Due to X.org being highly modular, packaging all X.org applications
+as their own independent packages would have created too many Debian
+packages. For this reason, some X.org applications have been grouped
+into larger packages: xutils, xutils-dev, x11-apps, x11-session-utils,
+x11-utils, x11-xfs-utils, x11-xkb-utils, x11-xserver-utils.
+Most packages, including the X.org server itself and all libraries
+and drivers are, however maintained independently.
+
+The Debian packaging is added by creating the "debian-*" git branch
+which contains the aforementioned "upstream-*" branch plus the debian/
+repository files.
+When a patch has to be applied to the Debian package, two solutions
+are involved:
+* If the patch is available in one of the upstream branches, it
+ may be git'cherry-picked into the Debian repository. In this
+ case, it appears directly in the .diff.gz.
+* Otherwise, the patch is added to debian/patches/ which is managed
+ with quilt as documented in /usr/share/doc/quilt/README.source.
+
+quilt is actually invoked by the Debian X packaging through a larger
+set of scripts called XSFBS. XSFBS brings some other X specific
+features such as managing dependencies and conflicts due to the video
+and input driver ABIs.
+XSFBS itself is maintained in a separate repository at
+ git://git.debian.org/pkg-xorg/xsfbs.git
+and it is pulled inside the other Debian X repositories when needed.
+
+The XSFBS patching system requires a build dependency on quilt. Also
+a dependency on $(STAMP_DIR)/patch has to be added to debian/rules
+so that the XSFBS patching occurs before the actual build. So the
+very first target of the build (likely the one running autoreconf)
+should depend on $(STAMP_DIR)/patch. It should also not depend on
+anything so that parallel builds are correctly supported (nothing
+should probably run while patching is being done). And finally, the
+clean target should depend on the xsfclean target so that patches
+are unapplied on clean.
+
+When the upstream sources contain some DFSG-nonfree files, they are
+listed in text files in debian/prune/ in the "debian-*" branch of
+the Debian repository. XSFBS' scripts then take care of removing
+these listed files during the build so as to generate a modified
+DFSG-free .orig.tar.gz tarball.

+The purpose of the X Display Manager Control Protocol (XDMCP)
+is to provide a uniform mechanism for an autonomous
+display to request login service from a remote host.
+By autonomous, we mean
+the display consists of hardware and processes that are independent of any
+particular host where login service is desired. (For example, the server
+cannot simply be started by a
+<function>fork/exec</function>
+sequence on the host.)
+An X terminal (screen, keyboard, mouse, processor, network interface)
+is a prime example of an autonomous display.
+</para>
+
+<para>
+From the point of view of the end user, it is very important to make
+autonomous displays as easy to use as traditional hardwired character
+terminals. Specifically, you can typically just power on a hardwired
+terminal and be greeted with a login prompt. The same should be possible
+with autonomous displays. However, in a network environment with multiple
+hosts, the end user may want to choose which host(s) to connect to. In an
+environment with many displays and many hosts, a site administrator may want
+to associate particular collections of hosts with particular displays. We
+would like to support the following options:
+</para>
+
+<itemizedlist>
+ <listitem>
+ <para>
+The display has a single, fixed host to which it should connect. It should be
+possible to power on the display and receive a login prompt, without user
+intervention.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+Any one of several hosts on a network or subnetwork may be acceptable
+for accepting login from the display.
+(For example, the user's file systems can be mounted onto
+any such host, providing comparable environments.) It should be possible
+for the display to broadcast to find such hosts and to have the display
+either automatically choose a host or present the possible hosts to the
+user for selection.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+The display has a fixed set of hosts that it can connect to. It should be
+possible for the display to have that set stored in RAM, but it should also be
+possible for a site administrator to be able to maintain host sets for a
+large number of displays using a centralized facility, without having to
+interact (physically or electronically) with each individual display.
+Particular hosts should be allowed to refuse login service, based on
+whatever local criteria are desired.
+ </para>
+ </listitem>
+</itemizedlist>
+
+<para>
+The control protocol should be designed in such a way that it can be used over
+a reasonable variety of communication transport layers. In fact, it is quite
+desirable if every major network protocol family that supports the standard X
+protocol is also capable of supporting XDMCP, because the end result of XDMCP
+negotiation will be standard X protocol connections to the display.
+However, because the number of displays per host may be large,
+a connection-based protocol appears less desirable
+than a connection-less protocol. For this reason the protocol is designed
+to use datagram services with the display responsible for sequencing and
+retransmission.
+</para>
+<para>
+<!-- .LP -->
+To keep the burden on displays at a minimum (because display cost is not
+a factor that can be ignored), it is desirable that displays not be required
+to maintain permanent state (across power cycles) for the purposes
+of the control protocol,
+and it is desirable to keep required state at a minimum while the
+display is powered on.
+</para>
+<para>
+<!-- .LP -->
+Security is an important consideration and must be an integral part of the
+design. The important security goals in the context of XDMCP are:
+</para>
+<itemizedlist>
+ <listitem>
+ <para>
+It should be possible for the display to verify that it is communicating
+with a legitimate host login service. Because the user will present
+credentials (for example, password) to this service,
+it is important to avoid spoof attacks.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+It should be possible for the display and the login service to negotiate the
+authorization mechanism to be used for the standard X protocol.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+It should be possible to provide the same level of security in verifying the
+login service as is provided by the negotiated authorization mechanism.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+Because there are no firm standards yet in the area of security,
+XDMCP must be flexible enough to accomodate a variety of security mechanisms.
+ </para>

+<para>
+<!-- .LP -->
+XDMCP is designed to provide authenticated access to display management
+services for remote displays. A new network server, called a \fIDisplay
+Manager\fP, will use XDMCP to communicate with displays to negotiate the
+startup of X sessions. The protocol allows the display to authenticate the
+manager. It also allows most of the configuration information to be
+centralized with the manager and to ease the burden of system administration
+in a large network of displays.
+The essential goal is to provide plug-and-play
+services similar to those provided in the familiar mainframe/terminal world.
+</para>
+<para>
+<!-- .LP -->
+Displays may be turned off by the user at any time. Any existing session
+running on a display that has been turned off must be identifiable. This
+is made possible by requiring a three-way handshake to start a session. If
+the handshake succeeds, any existing session is terminated immediately and a
+new session started. There is the problem (at least with TCP) that
+connections may not be closed when the display is turned off. In most
+environments, the manager should reduce this problem by periodically XSync'ing
+on its own connection, perhaps every five to ten minutes, and terminating the
+session if its own connection ever closes.
+</para>
+<para>
+<!-- .LP -->
+Displays should not be required to retain permanent state for purposes of
+the control protocol. One solution to packets received out of sequence
+would be to use monotonically increasing message identifiers in each message
+to allow both sides to ignore messages that arrive out-of-sequence. For
+this to work, displays would at a minimum have to increment a stable crash
+count each time they are powered on and use that number as part of a
+larger sequence number. But if displays cannot retain permanent state this
+cannot work. Instead, the manager assumes the responsibility for permanent
+state by generating unique numbers that identify a particular session and
+the protocol simply ignores packets that correspond to an invalid session.
+</para>
+<para>
+<!-- .LP -->
+The Manager must not be responsible for packet reception. To prevent the
+Manager from becoming stuck because of a hostile display, no portion of the
+protocol requires the Manager to retransmit a packet. Part of this means
+that any valid packet that the Manager does receive must be
+acknowledged in some way to prevent the display from continuously resending
+packets. The display can keep the protocol running as it will always know
+when the Manager has received (at least one copy of) a packet. On the
+Manager side, this means that any packet may be received more than once (if
+the response was lost) and duplicates must be ignored.

+XDMCP packets contain several types of data. Integer values are always
+stored most significant byte first in the packet ("Big Endian" order).
+As XDMCP will not be used to transport large quantities of data, this
+restriction will not substantially hamper the efficiency of any
+implementation. Also, no padding of any sort will occur within the packets.

+In an environment where authentication is not needed, XDMCP can disable
+authentication by having the display send empty Authentication Name
+and Authentication Data fields in the

+packet.
+In this case, the manager will not attempt to authenticate itself.
+Other authentication protocols may be developed, depending on local needs.

+In an unsecure environment, the display must be able to verify that the
+source of the various packets is a trusted manager. These packets will
+contain authentication information. As an example of such a system, the
+following discussion describes the "XDM-AUTHENTICATION-1" authentication
+system. This system uses a 56-bit shared private key, and 64 bits of
+authentication data. An associated example X authorization protocol
+"XDM-AUTHORIZATION-1" will also be discussed. The 56-bit key is represented
+as a 64-bit number in network order (big endian). This means that the first
+octet in the representation will be zero. When incrementing a 64-bit value,
+the 8 octets of data will be interpreted in network order (big endian).
+That is, the last octet will be incremented, subsequent carries propogate
