Upgrade to Automake 1.13.2 and Gnulib 20130529.

* .bzrignore: Add gnulib/lib/locale.h, man/**/*.log, man/**/*.trs,
  src/tests/*.log, and src/tests/*.trs.
* autogen.sh: Drop gnulib/gets.patch backport.
* gnulib/gets.patch: Remove.
* configure.ac (AM_INIT_AUTOMAKE): Set minimum Automake version to
  1.11.  Add parallel-tests option for compatibility with 1.11.
* man/Rules.man (TESTS_ENVIRONMENT): Move to ...
  (LOG_COMPILER): ... this.
* src/tests/Makefile.am (TESTS_ENVIRONMENT): Rewrite as a list of
  variable exports rather than as a command prefix, for
  compatibility with parallel-tests.
