WIP: Delete the automake support.
The meson build was in the last release, giving people a chance to switch. It provides faster builds with a smaller, easier build description language, so it's time to retire automake.
- developer docs build (!165)
- Test building xquartz
- more sha1 lib options
- libunwind support
#define FOO(meson) and
#define FOO 1(autotools)
