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.
The client ID is only needed for XRes, and autotools build ignores the
--clientids= arg if xres is disabled. We haven't made a meson option
for disabling tracking client ids (is it actually worth a build
option?), so just make this depend on xres.

Currently our meson.build just makes the assumption that the libc is
going to provide RPC functions. This doesn't actually seem to be the
case on Fedora, which causes compilation to fail unexpectedly:
../../Projects/xserver/os/rpcauth.c:47:10: fatal error: rpc/rpc.h: No such file or directory
#include <rpc/rpc.h>
^~~~~~~~~~~
compilation terminated.
So, in the event that we can't use libtirpc ensure that we actually
check whether or not the libc provides rpc/rpc.h. If it doesn't, raise
an error.

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.

Test to build xserver_poll.c was inverted compared to autoconf. Build
xserver_poll.c if poll is missing.

This is all just stuff we wish we had in libc, and some of this gets
used in eg. the dmx utilities build, so split it to its own library to
avoid pulling in xserver stuff.

This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far. The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet. The unit tests are also not done.
The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools. meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.
v2: Fix indentation nits, move version declaration to project(), use
existing meson_options for version-config.h's vendor name/web.
