Makefile: use automake rule for compiling .S

Automake seems to have its own rules for compiling an .o from an .S.
Essentially it does the same as our hand-crafted rule, but adds some
things like dependency file generation.

Remove our hand-crafted rule to use the automake rule, it is less
surprising.

Validate the protocol xml during scanning

Embed the wayland.dtd protocol data into the scanner binary so we can validate
external protocol files without requiring makefile changes. Hat-tip to Pekka
Paalanen for the embedding trick.
The embedding trick doesn't work well if the to-be-embedded file is in a
different location than the source file, so copy/link it during configure and
then build it in from the local directory.

The current expat parser is not a validating parser, moving scanner.c to
another parser has the risk of breaking compatibility. This patch adds libxml2
as extra (optional) dependency, but that also requires parsing the input
twice.

If the protocol fails validation a warning is printed but no error is returned
otherwise.

shm: Add shm_buffer ref and shm_pool unref functions

Sometimes the compositor wants to make sure a shm pool doesn't disappear
out from under it.

For example, in Enlightenment, rendering happens in a separate thread
while the main thread can still dispatch events.  If a client is destroyed
during rendering, all its resources are cleaned up and its shm pools are
unmapped.  This causes the rendering thread to segfault.

This patch adds a way for the compositor to increment the refcount of the
shm pool so it can't disappear, and decrement it when it's finished.

The ref/unref are asymmetrical (ref returns the pool) because it's
possible the buffer itself will be gone when you need to unref the pool.

This reverts commit fb7e13021730d0a5516ecbd3712ea4235e05d24d.

Developers have been trying to reduce the number of by default required
environment variables, and the mentioned commit is a step backwards in
that sense. The fundamental assumption is that a user has only one main
(Wayland) display server where all programs should connect to by
default, and do so with an a priori known socket name.

The commit also broke various use cases in the wild, some accidentally
due to other causes, some intentionally. This revert allows those use
cases to continue.

The original problem of running Weston in a window in an existing GNOME
X11 session and getting applications unintentionally launched into
Weston can be circumvented by letting Weston use a non-default socket
name, leaving wayland-0 unused.

configure.ac: bump to version 1.8.91 for the alpha release

client: require WAYLAND_DISPLAY to be set

Although defaulting to wayland-0 seems convenient, it has an undesirable
side effect: clients may unintentionally connect to the wrong compositor.
Generally, it's safer to fail instead. Here's a real example:

In Fedora 22, Gtk+ prefers Wayland over X11, though the default session is still
a normal X11 Gnome session. When you launch a Gtk+ app, it will try Wayland,
fail, then try X11, and succesfully start up. That works fine.

Now suppose you launch Weston while running the Gnome session. Suddenly, all
of the Gtk+ apps launched from Gnome will show up inside Weston instead.
That's unexpected. There's also no good way to prevent that from happening
(other than perhaps setting WAYLAND_DISPLAY to an invalid value when launching
an app).

Not using wayland-0 as the default will solve that problem: an app launched
from the X11 Gnome session will use the X11 backend regardless of whether
there's a wayland compositor running at the same time.

Everything else should work as before. The compositor already sets
the WAYLAND_DISPLAY when starting the session, so the lack of the default value
should not make a difference to the user.

build: always build wayland-scanner

The previous idiom for building a cross-compiled Wayland is to build once for
the build host (with --enable-scanner --disable-libraries) to get a
wayland-scanner binary that can then be used in a cross-compile (with
--disable-scanner).  The problem with this is that the cross wayland is missing
a wayland-scanner binary, which means you then can't do any Wayland development
on the target.

Instead, always build wayland-scanner for the target and change
--enable/disable-scanner to --with/without-host-scanner.  Normal builds use the
default of --without-host-scanner and run the wayland-scanner it just built, and
cross-compiled builds pass --with-host-scanner to use a previously built host
scanner but still get a wayland-scanner to install.

(a theoretically neater solution would be to build two scanners if required (one
to run and one to install), but automake makes this overly complicated)

COPYING: Update to MIT Expat License rather than MIT X License

MIT has released software under several slightly different licenses,
including the old 'X11 License' or 'MIT License'.  Some code under this
license was in fact included in X.org's Xserver in the past.  However,
X.org now prefers the MIT Expat License as the standard (which,
confusingly, is also referred to as the 'MIT License').  See
http://cgit.freedesktop.org/xorg/xserver/tree/COPYING

When Wayland started, it was Kristian Høgsberg's intent to license it
compatibly with X.org.  "I wanted Wayland to be usable (license-wise)
whereever X was usable."  But, the text of the older X11 License was
taken for Wayland, rather than X11's current standard.  This patch
corrects this by swapping in the intended text.

In practical terms, the most notable change is the dropping of the
no-advertising clause.

We were emitting the extern declarations of all types used in the protocol,

the -Wredundant-decls compiler flag when building an extension that uses
e.g. wl_surface. However we only need the extern declarations if the
protocol defines a factory for those external interfaces. That is a
bad design and can be however done by including the dependent protocol
header first.
So only emit the extern declarations for the types that the protocol
actually defines, this restoring the behavior we were using in 1.7.

protocol: Change wording of subsurface placement scheduling

Change wording to be more consistent with other parts of the subsurface
protocol. Before this change, wl_subsurface.set_position explicitly
stated that the new state was to be applied on the parents
wl_surface.commit and wl_subsurface.place_above/below only said "on
the next commit of the parent surface". What "committed" means is
ambiguous considering that a wl_surface.commit actually defers the
actual commit when in synchronized mode, but the intention has always
been that placement of a subsurface should be considered part of its
content, i.e. placement state should be applied when other state
(buffer, regions). This patch makes that more clear.

Note that prior to this patch, one could correctly have interpreted
the protocol meaning that placements operations takes effect explicitly
on wl_surface.commit of the parent surface no matter whether other state
of the parent surface is applied at that point. This patch clarifies that
that is not the case.
