DES isn't considered secure anymore for long time now, more and more platforms
dropping DES from their RPC implementations, and even the one where it came
from (Solaris) disabled it for a decade now. We have much better alternatives
(eg. passing creds via Unix socket for local connections, ssh tunneling,
MIT-MAGIC-COOKIE-1, ...), so it's unlikely anybody still really relying on it.
Therefore, sweep it out.

Most X servers, even those which do not have specific configuration
files, can use the directory specified by SERVER_MISC_CONFIG_PATH when
they have either the XSECURITY or XSELINUX extensions enabled, or when
support for DTRACE is enabled at build time, because this is also where
the "protocol.txt" file is searched for at runtime.
Unfortunately, the SERVER_MISC_CONFIG_PATH is set from serverconfigdir
which is hardcoded in the build system to "$prefix/$libdir/xorg", and
all X server builds share the same path.
That makes it harder for different X servers such as Xwayland to install
in the same path without sharing the same server configuration path
(and hence the same "protocol.txt" file).
Allow for the customization of server configuration path from the build
options so that different X servers can use completely different and
independent paths.

This adds support for XTEST in Xwayland using EIS, the emulated input
library [1].
To differentiate between X11 clients using XTEST, initiate a EI context
for each client and use the actual client name, from its command
line.
When an X11 client first tries to use XTEST to generate emulated input
events, a new connection to libEI is initiated by Xwayland on behalf
of the X11 client.
During that connection phase, the EI server will not be accepting
events until the emulated device is actually created, meaning that any
XTEST request from the X11 client will be discarded until the EI server
is willing to accept events.
To avoid that issue, add an event queue in Xwayland per X11 client that
will keep those requests, and dequeue them as soon as the EI server is
ready, i.e. once the EI device is added.
If the X11 client disconnects from the Xserver before the EI server is
ready, or if the connection is closed by the EI server, those events are
discarded and the queue cleared from any pending events.
For 10 minutes after the client disconnects, keep the internal struct
alive. If a client with the same commandline arguments connects again,
re-use the same struct. This means we are faster with the events the
second time around but it also allows the EIS server to pause individual
clients that keep sending intermittent events and disconnect immediately
(e.g. it'd be possible to pause xdtotool while an authentication prompt
is active).

Xwayland is usually spawned by the Wayland compositor which sets the
command line options.
If a command line option is not supported, Xwayland will fail to start.
That somehow makes the Xwayland command line option sort of ABI, the
Wayland compositor need to know if a particular option is supported by
Xwayland at build time.
Also, currently, Xwayland is being installed along with the rest of the
common executable programs that users may run, which is sub-optimal
because, well, Xwayland is not a common executable program, it's meant
to be a proxy between the Wayland compositor and the legacy X11 clients
which wouldn't be able to run on Wayland otherwise.
Xwayland would be better installed in `libexec` but that directory is
(purposedly) not in the user `PATH` and therefore the Wayland compositor
may not be able to find Xwayland in that case.
To solve both problems (which options are supported by Xwayland and
where to look for it), add a `pkg-config` file specifically for Xwayland
which gives the full path to Xwayland (`xwayland`) and which options it
supports (using `pkg-config` variables).
The `pkg-config` file also provides the `Version` so the build scripts
can check for a particular version if necessary.
Obviously, Wayland compositors are not required to use the `pkg-config`
file and can continue to use whatever mechanism they deem preferable.

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.
I don't think this is useful information to have in the log, and it's
a bunch of autotools and meson logic to produce it.

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.

Now that we can actually configure all of the directories xkb uses for
finding things, we can (finally, but only with meson) finally make it so
that with the correct meson configuration the Xserver will "just work"
without any additional changes to the installation prefix after
building.
For the people like me who have since scripted this part out of their
build process and forgotten about it, building and installing the X
server into a non-standard prefix has always required the following (or
something else that makes sure that X has a valid xkbcomp configuration)
commands be run right after doing the installation:
# start in root of prefix you installed X to
mkdir -pv share/X11/xkb/rules
ln -s /usr/share/X11/xkb/rules/evdev share/X11/xkb/rules/
rm -f bin/xkbcomp
ln -s /usr/bin/xkbcomp bin/
The one last piece of getting rid of this post-install junk is making
sure that we can control the directory that X uses for finding the
xkbcomp binary from meson so we can point it at the system provided
xkbcomp (/usr/bin/xkbcomp or similar). So, this patch adds a
configuration option for controlling this called xkb_bin_dir.
