Adam Jackson d8ec33fe05 glx: Use vnd layer for dispatch (v4)
The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.

Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.

v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.

v3: Add/remove the XID map from the vendor private thunk, not the
backend. (Kyle Brenneman)

v4: Fix deletion of ghost contexts (Kyle Brenneman)

Eric Anholt 1549e30372 Add a Meson build system alongside autotools.
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far.  The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools.  meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

v2: Fix indentation nits, move version declaration to project(), use
    existing meson_options for version-config.h's vendor name/web.

Keith Packard f3248eba6e ephyr: Handle window resize when using glamor
Under glamor, we need to re-create the screen pixmap at the new size
so that we can ask glamor for the associated texture. Fortunately, we
can simply use ephyr_glamor_create_screen_resources to create the new

Because this is being done after the server has started, we need to
walk the window heirarchy and reset any windows pointing at the old
pixmap. I could easily be convinced that this TraverseTree should be
moved to miSetScreenPixmap.

Keith Packard fb1edccf3c dix: Call screen block/wakeup handlers closest to blocking [v3]
The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.

Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.

Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.

These changes ensure that the following modules update the screen in
the correct order:

animated cursors        (uses RegisterBlockAndWakeupHandlers dynamically)
composite               (dynamic wrapping)
misprite                (dynamic wrapping)
shadow                  (static wrapping)
glamor                  (static wrapping)
driver                  (static wrapping)

It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.

[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes

ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.
