Emmanuele Bassi 0e325404aa build: Allow using gettext 0.17
This requires some autotools magic when setting up the environment
through autogen.sh, because autoreconf does not do the right thing
by default.

The correct order for setting up localization is:

  ‣ autopoint
  ‣ aclocal
  ‣ ...

otherwise aclocal will copy the system's gettext.m4 instead of honouring
the version we specified with AM_GNU_GETTEXT_VERSION in configure.ac.

# clutter package version number, (as distinct from shared library version)

# Making a point release:
# - increase clutter_micro_version to the next even number
# - increase clutter_interface_age to the next even number
# UNLESS there was an API addition/deprecation, in which case
# - set clutter_interface_age to 0
# After the release:
# - increase clutter_micro_version to the next odd number
# - increase clutter_interface_version to the next odd number
