Remove the global and Add a corresponding field to the vo struct, plus
another which tells whether the LAST config call was successful.The
latter value which tells whether the VO should be properly configured
at the moment seems a better match for the semantics actually needed
in most places where the old value was used. The 'count' field with
the old semantics is not currently used by anything, but I'm leaving
it there for vo drivers which would need those semantics if converted
to use the struct.
Existing uses of the global outside old vo drivers are either converted
to use the struct field or moved inside the vo_xyz() calls (instead of
"if (vo_config_count) vo_flip_page(..." just call vo_flip_page which
will now do nothing if not configured). The removal of the check in
mpcommon.c/update_subtitles() is less trivial than the others, but I
think it shouldn't cause problems.
Add a 'struct vo *vo' argument to the x11_common.c functions that
access the variable so it's available as vo->opts->vo_ontop. To keep
VOs using the old API working create a global vo variable that is set
to the currently used old vo. "vo_ontop" will be #defined to
"global_vo->opts->vo_ontop", and x11_common.h will add defines like
the following when it is included by old VOs:
#define vo_x11_ontop() vo_x11_ontop(global_vo)
so that they will call the function according to the new declaration.
