xorg-util-macros: update to 1.20.0.

This release fixes a deprecation warning when the macros are used with
autoconf 2.70 or later, and adds a new XORG_DEFAULT_NOCODE_OPTIONS
macro that can be used with packages that don't compile any code to
skip all the compiler checks done by XORG_DEFAULT_OPTIONS.  (Packages
will need to be updated to use this macro - that is in progress now.)

Alan Coopersmith (6):
      Build xz tarballs instead of bzip2
      gitlab CI: add a basic build test
      Fix spelling/wording issues
      gitlab CI: stop requiring Signed-off-by in commits
      Call AC_PROG_CC instead of AC_PROG_CC_C99 if autoconf >= 2.70
      Add XORG_DEFAULT_NOCODE_OPTIONS and bump version to 1.20.0
