fdc79fe72b edid: Prune duplicates after adding modes from DDC
Multiple calls to xf86EdidMonitorSet (which can be triggered e.g. by
running xrandr) would potentially keep adding the same modes, causing
the Monitor->Modes list to keep growing larger and using up more memory.

Fix this by calling xf86PruneDuplicateModes after adding the modes
returned by xf86DDCGetModes. This makes sure there's only one instance
of each unique mode in the list.

v2:
* Replace semicolon with {} for empty for loop (Emil Velikov)
* Slightly tweak commit log to avoid minor inaccuracy about what
  xf86PruneDuplicateModes does

8805a48ed3 glamor: avoid a crash if texture allocation failed
Texture creation in _glamor_create_tex() can fail if a GL_OUT_OF_MEMORY
is raised, in which case the texture returned is zero.

But the texture value is not checked in glamor_create_fbo() and glamor
will abort in glamor_pixmap_ensure_fb() because the fbo->tex is 0:

  Truncated backtrace:
  Thread no. 1 (10 frames)
   #4 glamor_pixmap_ensure_fb at glamor_fbo.c:57
   #5 glamor_create_fbo_from_tex at glamor_fbo.c:112

   #11 compCheckRedirect at compwindow.c:167
   #12 compRealizeWindow at compwindow.c:267
   #13 RealizeTree at window.c:2617

Check the value returned by _glamor_create_tex() in glamor_create_fbo()
and return NULL in the texture is zero.

All callers of glamor_create_fbo() actually check the returned value and
will use a fallback code path if it's NULL.

Please cherry-pick this to active stable branches.

e33be78e2a xfree86: Remove 24bpp pixmap format support (v2)
There's really no reason to pretend to support this, apps hate it, all
we're doing is giving people a way to injure themselves. It doesn't work
anyway with any Radeon, any NVIDIA chip, or any Intel chip since i810.
Rip out all the logic for handling 24bpp pixmaps and framebuffers, and
silently ignore the old options that would ask for it.

The cirrus alpine driver has been updated to default to 16bpp, and both
it and the i810 driver can now use the 32->24 conversion code in shadow
if they want. All other drivers support 32bpp. Configurations that
explicitly request 24bpp in order to fit in VRAM will be broken now
though.

04b4bad7c0 glamor: glamor_set_destination_drawable() can fail
The fbo_array of a given glamor pixmap can be NULL in some cases, as
glamor_create_fbo_array() can fail to allocate the FBO array.

If this is the case, glamor_pixmap_fbo_at() will return NULL even though
the box index is valid, and glamor_set_destination_drawable() simply
assumes glamor_pixmap_fbo_at() will return an FBO prior to pass the
value to glamor_set_destination_pixmap_fbo(), which will segfault.

We need a way for glamor_set_destination_drawable() to fail safely and
let the caller know about the failure.

Add a boolean return value to glamor_set_destination_drawable() for that
purpose.

bca2216090 xfree86: work around a sdksyms problem with gcc5 on Cygwin
The linemarkers in the preprocessor output from gcc5 on Cygwin have
canonicalized paths to included files (e.g. xserver/build/../include/misc.h
is canonicalized to xserver/build/include/misc.h). (see gcc svn rev 210264,
which causes the transformation performed by -fcanonical-system-headers to
be applied to all include pathnames)

These canonicalized paths won't match $topdir, so sdksyms doesn't look at
the contents of those headers for sdk exported symbols.

Workaround this by canonicalizing all the paths we consider, using readlink.

v2:
Keep a cache of readlink results so it isn't quite so dreadfully slow.

0d7f05ed99 miarc: "Cache" arc span data for dashed arcs
This avoids recomputing the span data for every dash. x11perf thinks
this is a pretty modest speedup:

    832919.4       840471.1 ( 1.009)   100-pixel dashed ellipse
    672353.1       680652.2 ( 1.012)   100-pixel double-dashed ellipse
     13748.9        24287.9 ( 1.767)   100-pixel wide dashed ellipse
      9236.3        21298.2 ( 2.306)   100-pixel wide double-dashed ellipse

But part of the reason it's so modest there is that the arcs are
relatively small (100 pixel diameter at line width 10, so ~6000 pixels)
and the dashes relatively large (30 on 20 off so ~6 dashes per
quadrant).

With larger arcs and finer dashes this is much more impressive. A fairly
trivial testcase of a single 15000x13000 arc with the default {2, 2}
dash pattern drops from ~3500 milliseconds to 10 milliseconds.

feed7e3f98 xfbdev: Remove
With the shadow framebuffer overallocation bug fixed (ref below), Xorg +
fbdev has tens to hundreds of kilobytes more baseline memory usage than
Xfbdev. That's not nothing, but it's little enough that we should focus
our efforts on the server that actually gets development attention.

3dad57b121 sdksyms: Tighten up the symbols we add to the magic table
The code as written would match anything declared extern. _X_EXPORT is
what we really mean here. That's a macro, so check for what it expands
to and skip if not found.

dc7ceda90f dispatch: Mark swapped dispatch as _X_COLD
This touches everything that ends up in the Xorg binary; the big missing
part is GLX since that's all generated code. Cuts about 14k from the
binary on amd64.

8c9909a992 xwayland: Make sure we have a focus window
During the InitInput() phase, the wayland events get dequeued so we
can possibly end up calling dispatch_pointer_motion_event().

If this occurs before xwl_seat->focus_window is set, it leads to a NULL
pointer derefence and a segfault.

Check for xwl_seat->focus_window in both pointer_handle_frame() and
relative_pointer_handle_relative_motion() prior to calling
dispatch_pointer_motion_event()  like it's done in
pointer_handle_motion().
