Done. At the moment, AC_PREREQ is 2.50, so 2.13 will fail. Even the
changes between 2.52 and 2.53 in the generated configure are huge, so
2.53 should be the "official" version.

This could be done in two ways:
- allow people to continue to use, say, 2.52, and just ask that 2.53
  is used when committing; or
- bump AC_PREREQ to 2.53; 2.52 (and earlier) will then refuse to work.
It's your choice.

The other issue is caching: autoconf 2.50 will, by default, not
generate a config.cache, since that has caused too many problems.
Again, two options:
- leave it as-is, and suggest that people who want caching use the -C
  option of configure (new in 2.5x), or
- hack configure to create a cache file by default (I'm not sure how
  to do this)
