autotools: remove autotools

At this point meson is pretty well tested and seems to pretty much work,
so we can consider dropping an extra build system.

This doesn't solve the problem that pixman's release scripts are part of
the autotools build system (as make targets). One solution might be to
use xorg's release.sh instead.

-#   Pixman versioning scheme
-#
-#   - The version in git has an odd MICRO version number
-#
-#   - Released versions, both development and stable, have an
-#     even MICRO version number
-#
-#   - Released development versions have an odd MINOR number
-#
-#   - Released stable versions have an even MINOR number
-#
-#   - Versions that break ABI must have a new MAJOR number
-#
-#   - If you break the ABI, then at least this must be done:
-#
-#        - increment MAJOR
-#
-#        - In the first development release where you break ABI, find
-#          all instances of "pixman-n" and change them to pixman-(n+1)
-#
-#          This needs to be done at least in 
-#                    configure.ac
-#                    all Makefile.am's
-#                    pixman-n.pc.in
-#
-#      This ensures that binary incompatible versions can be installed
-#      in parallel.  See http://www106.pair.com/rhp/parallel.html for
