[PATCH 2/2] maint: update gnulib to latest

[Bernhard Voelker]

Run 'make update-gnulib-to-latest'.

* bootstrap: Sync from gnulib/build-aux/bootstrap.
* gnulib: Update to latest.
* configure.ac (AC_PREREQ): Change from very old 2.59 to current 2.69
to avoid gnulib-tool complaining about "minimum supported autoconf
version is 2.63".
