* let's run 'make clean-src' when typing 'make clean', since make clean-bin won't be used anyway. The user is informed of this through a message.

* Renamed "Advanced" subcat of "Input / Codecs" into "General" and made all the advanced options within it hidden.

vlccontrol.cpp: fixed a bug when processing target options stored in a safe array, last element in array was never processed

  This is really dirty btw. the OS X GUI module has some serious memory management issues.

(it was not padding properly the end of encoded stream)

* wizard.*: added the display-option to the advanced-transcoding and the advanced-streaming options (-> it's displayed only once, since only one of these pages is displayed at a one run)
* THANKS: added zcot's patch ;)

  "Session Announcement Protocol"

* Thanks to Meuuh for the feedback. threads prioritization should work now, without annoying error messages.
* If an rt-offset is specified, then this offset is not applied to the main thread, because it's value cannot yet be retrieved at that time (same as before, but now without annoying error).

* Simplify something of [12852]

* This patch does what the revert'ed patch from before should have done. Changing priorities of vlc threads with --rt-priotity and --rt-offset. (Note that 'rt' isn't 'realtime'. We should use Mach threading for that on Darwin)
* It also fixes the errors on the non-existent  rt-priority and rt-offset on start, which was caused because no config was loaded yet.

- Run-time check for IDN

* converted it to a scandir system

Please test this heavily on all your files and directories, because these routines are triggered on each opening of a file. If someone would like to review it for leaks and memory messups, I would be eternal grateful.

RTP reordering in module/access/udp.c done by me with help from Marian Durkovic (md _AT_ bts _dot_ sk). Allow src/input/stream.c to handle a linked list of blocks from demuxers.

* Fix an OSX only issue with accents and other weird chars in subtitle filenames when using the "forced" method.
