Differences from autotools:
* Autotools defined NO_ALLOCA for OSX builds. I don't think we need
this anymore as Xalloc.h is no longer used anywhere in the xserver.
* X11.bin is linked with -u,miDCInitialize, and then libserver_mi
provided to satisfy (just) that. It's been that way since the commit
which added it. We can't write the equivalent in meson due to linker
argument ordering issues, but do we really need to?
* An explicit -Dsecure-rpc=false is required for OSX, since in meson we
don't do the checks that XTRANS_SECURE_RPC_FLAGS did for the existence
of the specific RPC functions required.

meson.build has code to set the module_dir variable to
${libdir}/xorg/modules if the module_dir option string is empty.
However, this has several problems:
1. The variable is only used for an unused @moduledir@ substitution in
the man page. The rule for xorg-server.pc uses option('module_dir')
directly instead.
2. The 'module_dir' option has a default value of 'xorg/modules' so the
above rule doesn't do anything by default.
3. The xorg-server.pc rule uses ${exec_prefix}/option('module_dir'), so
the effect of #2 is that the default moduledir is different between
autoconf and meson. E.g. if ${prefix} is /X, then you get
autoconf: moduledir=/X/lib/xorg/modules
meson: moduledir=/X/xorg/modules
Fix this by using the module_dir variable when generating xorg-server.pc, and by
using join_paths() to assign module_dir unconditionally.
v2: Keep the 'xorg/modules' default path, but use join_paths() unconditionally (Thierry Reding)

This adds initial support for displaying Xwayland applications through
the use of EGLStreams and nvidia's custom wayland protocol by adding
another egl_backend driver. This also adds some additional egl_backend
hooks that are required to make things work properly.
EGLStreams work a lot differently then the traditional way of handling
buffers with wayland. Unfortunately, there are also a LOT of various
pitfalls baked into it's design that need to be explained.
This has a very large and unfortunate implication: direct rendering is,
for the time being at least, impossible to do through EGLStreams. The
main reason being that the EGLStream spec mandates that we lose the
entire color buffer contents with each eglSwapBuffers(), which goes
against X's requirement of not losing data with pixmaps. no way to use
an allocated EGLSurface as the storage for glamor rendering like we do
with GBM, we have to rely on blitting each pixmap to it's respective
EGLSurface producer each frame. In order to pull this off, we add two
different additional egl_backend hooks that GBM opts out of
implementing:
- egl_backend.allow_commits for holding off displaying any EGLStream
backed pixmaps until the point where it's stream is completely
initialized and ready for use
- egl_backend.post_damage for blitting the content of the EGLStream
surface producer before Xwayland actually damages and commits the
wl_surface to the screen.
The other big pitfall here is that using nvidia's wayland-eglstreams
helper library is also not possible for the most part. All of it's API
for creating and destroying streams rely on being able to perform a
roundtrip in order to bring each stream to completion since the wayland
compositor must perform it's job of connecting a consumer to each
EGLstream. Because Xwayland has to potentially handle both responding to
the wayland compositor and it's own X clients, the situation of the
wayland compositor being one of our X clients must be considered. If we
perform a roundtrip with the Wayland compositor, it's possible that the
wayland compositor might currently be connected to us as an X client and
thus hang while both Xwayland and the wayland compositor await responses
from eachother. To avoid this, we work directly with the wayland
protocol and use wl_display_sync() events along with release() events to
set up and destroy EGLStreams asynchronously alongside handling X
clients.
Additionally, since setting up EGLStreams is not an atomic operation we
have to take into consideration the fact that an EGLStream can
potentially be created in response to a window resize, then immediately
deleted due to another pending window resize in the same X client's
pending reqests before Xwayland hits the part of it's event loop where
we read from the wayland compositor. To make this even more painful, we
also have to take into consideration that since EGLStreams are not
atomic that it's possible we could delete wayland resources for an
EGLStream before the compositor even finishes using them and thus run
into errors. So, we use quite a bit of tracking logic to keep EGLStream
objects alive until we know the compositor isn't using them (even if
this means the stream outlives the pixmap it backed).
While the default backend for glamor remains GBM, this patch exists for
users who have had to deal with the reprecussion of their GPU
manufacturers ignoring the advice of upstream and the standardization of
GBM across most major GPU manufacturers. It is not intended to be a
final solution to the GBM debate, but merely a baindaid so our users
don't have to suffer from the consequences of companies avoiding working
upstream. New drivers are strongly encouraged not to use this as a
backend, and use GBM like everyone else. We even spit this out as an
error from Xwayland when using the eglstream backend.

Querying a pkg-config variable using the --variable option produces the
value of the given variable as stored in the pkg-config file and should
not be used to add directories to the include search path.
The reason for this is that it breaks cross-compilation, because header
files are installed relative to the host sysroot. pkg-config supports a
PKG_CONFIG_SYSROOT_DIR environment variable that points to this sysroot
and will prepend that to the path of directories in -I or -L options in
pkg-config's Cflags, Libs or Libs.private keywords. However, because no
context can be inferred from variable names, as opposed to the keywords
with fixed meaning, the sysroot path will not be prepended to them. The
build system is responsible for doing so if necessary since it is aware
of the context in which the variable is used.
Adding the include directory returned by pkg-config to the include path
leaks build system information into the cross-build and break with very
confusing errors such as this:
In file included from include/misc.h:82:0,
from dix/atom.c:55:
/usr/include/pthread.h:682:6: warning: '__regparm__' attribute directive ignored [-Wattributes]
__cleanup_fct_attribute;
^~~~~~~~~~~~~~~~~~~~~~~
or this:
In file included from include/misc.h:139:0,
from dix/atom.c:55:
/usr/include/stdlib.h:133:8: error: '_Float128' is not supported on this target
extern _Float128 strtof128 (const char *__restrict __nptr,
^~~~~~~~~
Fix this by replacing the include directory with the appropriate xproto
dependency required to add the correct include directory to the compile
command for subdirectories that are missing the dependency. As detailed
above, this gives pkg-config the opportunity to prepend the sysroot for
all paths in -I compiler options.

The newline in the middle of the awk expression confuses Meson and
causes it to pass only the string before the newline to awk, which will
subsequently fail because it encounters an unterminated string.
One fix would be to escape the newlines ('\\n'), but that causes the
newline to end up in the pkg-config file and separate the ABI version
lines by blank lines.
Instead, simply drop the newlines to make the generated pkg-config file
look more like the one generated as part of the autotools-based build.

When starting a lease, mark leased CRTCs as disabled and hide

non-leased CRTCs which are driving leased Outputs and mark
them as disabled as well. Sometimes an application will lease
an idle crtc instead of the one already associated with the
leased output.
When terminating a lease, reset any CRTCs which are driving
outputs that are no longer leased so that they start working
again.
This required splitting the DIX level lease termination code
into two pieces, one to remove the lease from the system
(RRLeaseTerminated) and a new function that frees the lease
data structure (RRLeaseFree).
v4: Report RR_Rotate_0 rotation for leased crtcs.
v5: Terminate all leases on server reset.
Leases hang around after the associated client exits so that
the client doesn't need to occupy an X server client slot and
consume a file descriptor once it has gotten the output
resources necessary.
Any leases still hanging around when the X server resets or
shuts down need to be cleaned up by calling the kernel to
terminate the lease and freeing any DIX structures.
Note that we cannot simply use the existing
drmmode_terminate_lease function on each lease as that wants
to also reset the video mode, and during server shut down that
modesetting: Validate leases on VT enter
The kernel doesn't allow any master ioctls to run when another
VT is active, including simple things like listing the active
leases. To deal with that, we check the list of leases
whenever the X server VT is activated.
