ProcVidModeGetGamma() relies on GetGamma() to initialise values if it
returns TRUE. Without this, we're sending uninitialised values to
clients.
Fixes: xorg/xserver#1040
Now that each source and header should be in order, we can safely cleaup
the last remaining bits from the main `xwayland.h` which is not needed
anymore and can be removed.

change the resolution when going fullscreen.

crtc->mode reflects the mode set through the xrandr extension, once we
add support for also changing the mode through the vidmode extension this
will no longer correctly reflect the emulated resolution.
Add a new xwlVidModeGetCurrentRRMode helper which determines the mode by
looking at the emulated_mode instead.
Likewise add a xwlVidModeGetRRMode helper and use that in
xwlVidModeCheckModeForMonitor/xwlVidModeCheckModeForDriver to allow any
mode listed in the randr_output's mode list.
This is a preparation patch for adding emulated mode/resolution change
support to Xwayland's XF86 vidmode extension emulation.

Some games (namely openttd) will raise an XError and fail with a
BadValue if their request to XF86VidModeSetViewPort fails.
Support only the default zoom and viewport, fail for everything else.

Older games (mostly those based on SDL 1.x) rely on the XVidMode
extension and would refuse to run without.
Add a simple, limited and read-only xvidmode support that reports the
current mode used so that games that rely on xvidmode extension can run
on XWayland.
