osd_libass: allocate separate ASS_Library for OSD

osd_libass.c used the same ASS_Library object as the player core. This
caused a problem: when playing a new file, all fonts loaded by the
ASS_Library object were unloaded, including the OSD font. Parts of the
OSD would stop being rendered correctly.

Solve this by creating a separate ASS_Library, with its own set of
fonts.
