DMX glxproxy: Don't allocate & copy data just to free it unused

Two functions in the DMX glxproxy code loop over all the backend
screens, starting at the highest numbered and counting down to
the lowest.

Previously, for each screen, the code would allocate a buffer
large enough to read the reply from the backend, copy that reply
into the buffer, and then if it wasn't the final screen, free it.
Only the buffer from the final screen is used, to pass on to the
client in the reply.

This modifies it to just immediately discard the responses from
the screens as we loop through it, only doing the allocate & copy
work for the one buffer we pass back to the client.

Xorg binary: use install-exec-hook rather than install-exec-local

The former was explicitly designed to execute additional code after the binary
has been installed. The latter can be executed in any order, hence it's
current dependency on install-binPROGRAMS as a workaround.

The CYGWIN libXorg.exe.a target is an installation target rather than
a post-installation one, so it should not be done as a hook. It does not depend
on the Xorg executable being installed.

Automake:
"These hooks are run after all other install rules of the appropriate type,
exec or data, have completed. So, for instance, it is possible to perform
post-installation modifications using an install hook".

"With the -local targets, there is no particular guarantee of execution order;
typically, they are run early, but with parallel make, there is no way
to be sure of that".

damage: Remove the 'damage window' resource type.

Note that the existing code never actually creates a resource of this

window destruction and clean up any associated Damages, but that's

xnest: Ignore GetImage() error in xnestGetImage()

When an Xnest instance is not viewable it will crash when a client in
that instance calls GetImage. This is because the Xnest server will
itself receives a BadMatch error.
This patch ignores the error. The application which has requested the
image will receive garbage - this however is fully legal according
to the specs as obscured areas will always contain garbage if there
isn't some sort of backing store as discussed in

Xnest: Implement xnestModifyPixmapHeader

Xnest variant of ModifyPixmapHeader that creates new Pixmap in parent X
server if it's size is modified from 0x0 to anything bigger.

xnestCreatePixmap doesn't create pixmap in parent X server if it has
dimensions 0x0. If it is later resized and accessed, Xnest will be
aborted with BadDrawable error from parent X server because it will
use XID 0. This happens with ScratchPixmap, for example as used from
XaceCensorImage. Applications using XACE crash Xnest.

os: Immediately queue initial WriteToClient

If we immediately put the WriteToClient() buffer into the socket's write
queue, not only do we benefit from sending the response back to client
earlier, but we also avoid the overhead of copying the data into our own
staging buffer and causing extra work in the next select(). The write is
effectively free as typically we may only send one reply per client per
select() call, so the cost of the FlushClient() is the same.

shmget10:   26400 -> 110000
getimage10: 25000 -> 108000

shmget500:   3160 -> 13500
getimage500: 1000 -> 1010

The knock-on effect is that on a mostly idle composited desktop, the CPU
overhead is dominated by the memmove in WriteToClient, which is in turn
eliminated by this patch.

miSyncSetup was checking to see if the screen private key had been

Instead, it should register the private index only once, but then
