- Remove an useless variable

- Add support for RTP padding

By the way, the MPEG-Video parser seems to ignore the MP2V specific
extra header (i.e. it passes it onto the demux instead of removing it).
Not sure if this is intended (any MPEG expert?)

Mac OS X gui: Revert [19198] (add items to the playlist in the finder's order). The finder provides elements that may be shuffled.

Mac OS X gui: Fix a rare bug of non-update of the vout's title. The manage-ing thread can't be trust on input change.

Mac OS X gui: Don't try to change the interface from a non-main thread. (Should fix a remanence bug in the controller scroll field)

May need a few more vertical spacer, after the last tab (Capture) will be added.

- control APIs: do not crash if exception parameter is null, that means caller is not interested in exceptions

Mac OS X gui: Don't yield input more than needed. (End of the set of changes that makes quitting really fast.)

- Warn that WxWidgets is deprecated.
- Fix a few Wx error messages.

Comment out a few non-thread-safe functions from embedded vout
handling. Fixes a crash when playlist item changes. refs #955

* modules/codec/x264.c: Add support for multipass encoding. Slightly alter stats behaviour to reflect same usage as x264 cli (only one stats file). Needs testing..

should be increased. Fixes a few crashes when input changes.

Mac OS X gui: Make sure libvlc exit properly. Don't forward the closeVout: if the interface is dead.
