Add support for the meson build system

This produces virtually the same installed tree as the autotools builds with
the following exceptions:

- rules symlinks is no longer supported. This option is 16y old and likely
  hasn't been used in the last decade or so
- the xkeyboard-config.pc file uses expanded paths now, e.g.
   xkb_base=/usr/share/X11/xkb
  vs autotools'
   xkb_base=${datarootdir}/X11/xkb
  The values are the same for both so this is not a functional change.
- substitutions in the man page are hardcoded since we can't use the m4
  XORG_MACROS. This appears to only matter for the miscmansuffix and there
  only for solaris up to including 11.3. so... meh?
- the .mo files differ, but it's hard to say why since they're generated
