Qt4 - Media Info. Re-add some info for DVB. Clean the in_Edit state that was stored two times in different classes.

and fix a few minor leaks

This saves:
 - one malloc() per packet per client } due to
 - one memcpy() per packet per client } block_Duplicate()
 - one mwait() per packet per client, and
 - one thread per client per track

So it should really help scale RTSP broadcast up.
However, in its current state, it removes the pts synchronization,
which might not be such a great idea. I will re-add it later.

ADD a $STRIP option to bootstrap because x264 needs it

with numbers to be solved.

(I haven't checked whether the UI labels need updating)

Qt4 - Define a TOGGLEV to toggleVisible on QWidgets, and use it instead of rewriting the code n times.

Qt4 - Sout: hide SAP options and ttl options when you don't stream. Adapt the label on the okButton according...

Qt4 - Main Interface: hiding menus does hide the controls and the statusBar. Still a lot of problems with that code, but at least it can be reverted.

Only basics options are done ( AVCodec + Muxer mainly ).
Two profiles are done. If you want to add more, then search "ADD HERE" in sout.cpp.
Reindentation of older code.
