* modules/codec/libmpeg2.c: make sure there are no more linked pictures

* modules/audio_filter/converter/s16tofloat32swab.c:
   added an #ifdef HAVE_ALLOCA.

* gtk2_api.cpp: made valgrind happy ;)

 * modules/gui/beos/*: added _()s so the whole interface is translated
 * src/libvlc.c: ask gettext for UTF-8 strings (under BeOS only for now)
   FIXME: currently, untranslated strings are not converted to UTF-8

* modules/codec/libmpeg2.c: fixed aspect ratio problem.

*All: fixed unwanted fileinfo window refresh under windows.

* modules/misc/network/ipv4.c: a bit of cleanup.

* a bit of code cleaning

* configure.ac.in: print an error message if libmpeg2 is not found or too old.

* configure.ac.in: the libmpeg2 plugin is now enabled by default when the right version of libmpeg2 is detected (0.3.2 aka cvs).
