* Makefile.am: New file version.c, generated at each 'make' command.

 * toolbox: New --update-version switch, which builds the version.c file
   from current date, user/hostname/domainname, compiler version and
   svn changeset.
 * src/libvlc.c: Exported API to access data from version.c.
 * modules/control/http.c: New variables vlc_compile_time, vlc_compile_by,
   vlc_compile_host, vlc_compile_domain, vlc_compiler and vlc_changeset.
