* SAP : coding style fixes
* Some fogotten playlist_*Info

* Fix deadlock with preparse

* Each module can declare a "human-readable short name" with set_name
* Modules are sorted by category (set_category, set_subcategory).
  Modules configs can be separated by set_section()
* Separated audio-filter and audio-visual
* Separated extraintf and control
* New command and widget : add_module_list() for comma-separated modules
* Vfilters now use "," as separator

* src/misc/vlm.c, modules/demux/playlist/m3u.c, modules/services_discovery/sap.c: portability fixes.

some more size verifications

* fix bug in SDP parser

wx: really commit last commit

 * support incorrect announces that does not include parameters we don't
   parse anyway, change the corresponding msesage from Warn to Dbg.
 * convert UDP to udp, to get the right icon in the playlist
 * fixed a potential crash given away by gcc's warnings

* Fix playlist release bug
* Add sdp and rtp as network type items

* Autodelete items played by the SDP demuxer
* Added playlist_CopyParents facility, for modules that use ItemToNode

  - added a demuxer for SDP files. this is a temporary submodule to handle SDP files with UDP streams for so long as liveMedia doesn't support these yet.

* modules/demux/avi/avi.c: Look a bit further into the file for the avi tag.
  this allows you to play avi in uncompressed .rar (only first part of course).

  - some code cleanup. Please watch coding style people.
* demux/sgimb.c: fix an alloc

  - The SAP handler now runs in a separate thread.
  - RTP sessions can be announced with sap (sdp=sap://,name=...)
	TODO: Make this more configurable
  - Better SDP generation (the timestamp problem is not resolved)
	About this, there is a problem : as, for a RTP session, the URI
        is the complete SDP, if the session is recreated, as the URI has 
        changed, a new item is added to the playlist
  - Experimental flow control algorithm :
       It does not follow the "Recommended" implementation, as it needs
       to count the sessions (to achieve this, we should make this work
       together with the SAP listener)
       It is disabled by default (use --sap-flow-control to enable).
       When it is disabled, sap announcement interval is set by --sap-interval

* src/misc/net.c : created net_ReadNonBlock
* sap.c : Fixed memory problem
