I_PL_REPEAT/I_PL_LOOP/I_PL_RANDOM etc. strings as done after
toggleRepeat usage etc.
Patch by Ilkka Ollakka

Patch from Hannes Domani.

control/media_instance.c: Ignore the exception raised by libvlc_get_input_thread in libvlc_media_instance_play.

include/vlc_arrays.h: Transform the dictionary macro to static inline, and publish a vlc_dictionary_t type.

Subsdec: Split the decoder for subsdec / SSA / USF in three files, since the code has grown a bit too much in order to improve readability.
Some functions may still need to be renamed and moved from a file to another.
I hope it is done in the correct way, if not, tell me or revert.

control/media_instance.c: Support libvlc_MediaInstanceReachedEnd event for upcoming media_list_player.
