Non-linux GNU systems such as Hurd will define __GLIBC__ or __GNU__
rather than __linux__. This must be tested for in order to get byteswap.h
included. See commit 594d180fe4 (24 Dec
2006) and other related patches (fixed in upstream HEAD then, why was
the patch not brought across to the 1.3 branch?).
The xf86 mode setting code was mis-using this field to try and store a
pointer to a DisplayModeRec, however, each output has its own copy of every
DisplayModeRec leaving the one in in the RRModeRec devPrivate field pointing
at a random DisplayModeRec.
Instead of attempting to rectify this, eliminating the devPrivate entirely
turned out to be very easy; the DDX code now accepts an arbitrary RRModeRec
structure and set that to the hardware, converting it on the fly to a
DisplayModeRec as needed.
Freeing resources during client closedown can cause cursor changes which
attempt to send cursor events through the XFixes extension; a client in the
process of closing down has no file to send events to, causing a crash when
this path is hit.

The RandR protocol spec has several requests in support of user-defined
modes, but the implementation was stubbed out inside the X server. Fill out
the DIX portion and start on the xf86 DDX portion. It might be necessary to
add more code to the DDX to insert the user-defined modes into the output
mode list.
This instruction is being used in some debug VBIOSes. This implementation
doesn't even try to be accurate. Instead, it just increments the counter by a
fixed amount every time an rdtsc instruction in encountered, to avoid divides by
zero.
in xf86CrtcSetMode, scrn->pScreen will be NULL during server startup time,
so don't try to set the subpixel order. subpixel order will be set in the
randr initialization anyways.
New modes header files required a few minor changes to be used by external
drivers, the most notable of which is the publication of the config file
parser header files.
Add monitor "Rotate" option taking one of "normal", "left", "inverted" or
"right". However, because initial mode selection is made before the screen
is completely initialized, we cannot create the shadow pixmap object at this
point. Pend the shadow pixmap creation until the block handler.
Note that this code is not completely functional yet.
RandR 1.0 sizeID must be computed the same way every time, so when reporting
it in the ScreenChangeNotify event, just construct the usual 1.0 data block
and use that.
subpixel geometry information can be computed by looking at the connected
outputs and finding any with subpixel geometry and using one of those for
the global screen subpixel geometry. This might be improved by reporting
None if more than one screen has information and they conflict.
This code comes from the intel driver, so there's no history in this tree.
As the crtc/output-based mode selection code uses ddc, the ddc and i2c
modules have been merged into the server. Attempts to load them are safely
ignored now.
This was caught by distributions upgrading damageproto to 1.1, before the
server they had supported it. The server then advertised the new version
without supporting the protocol.

It was using REQUEST_SIZE_MATCH (client request length must equal request size)
rather than REQUEST_AT_LEAST_SIZE (client request length must be at least
big enough for request size), and this request has data following the request
structure.
(cherry picked from commit 4f2f3233c8)
This keeps us from having to define _POSIX_C_SOURCE, _BSD_SOURCE, and
_XOPEN_SORUCE to get the C environment we want in different places. It also
fixes the build on linux due to RTLD_DEFAULT having not been defined.

The previous mechanism failed when finding drm symbols now that libdrm has
moved to being linked by libdri instead of being linked into the server.
