Thierry Reding f3b0a2aee2 meson: Remove usage of pkg-config --variable=includedir
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.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
