for "rate-faster" and "rate-slower". input_ControlPush will handle it. This
fixes a race condition when "rate" ends up at a different value than
p_input->i_rate

+ code cleaning

* fix to the hotkeys on OSX: RECORD start/stop is cmd-shift-r, HISTORY_BACK/_FORWARD ctrl-v/ctrl-b now, as '[' and ']' are unaccessible on German keyboards

* modules/video_output/x11/xcommon.c, modules/video_output/directx/events.c: added support for insert/delete hotkeys.

* include/vlc_playlist.h, src/playlist/playlist.c, src/video_output/video_output.c: added a lock to the playlist garbage collector to avoid a race condition with the vout creation/destruction.

* modules/codec/x264.c: crop the video if its size isn't a multiple of 16 (will have to be changed to use the visible size values).

 recording (simple dumping). (Usefull for dvb/udp/mp3 radio stream).

 * mpjpeg.c: use sout_CfgParse !

 * ts: - set BLOCK_FLAG_CORRUPTED on transport_error_indicator.
       - better support of EIT + VLC_META_NOW_PLAYING.

 * input: allow chaining of access_filter (like filter1:filter2 ...)
 * es_out: support VLC_META_NOW_PLAYING for multi-program stream.

(fix a 302 message...)
