Grrr a library that does exit on its own !

Noticed by courmish.

(X11 has a similar bug, not to how to fix it)

It fixes an assert in vout code when a stream was stopped while paused.

It was created as an integer and set as a boolean...

N.B.: libvlc snapshots remain seriously broken.
Vout is not locked when shooting. Variables are not safely set.
Vout thread does not access request field safely.
Multiple requests are not safe either. I probably missed some other
issues.

C++ is always so much fun ;)

It still does not work because of [2413].

+ Remove this->
+ Remove toNativeSeparators

No functionnality changes yet as the demuxers need to honor it.

 I have add an extra bool to  DEMUX_SET_POSITION/TIME to ask for precise
seeking to the demuxer.
(You cannot have precision and speed when seeking with non intra only codec).

this patch features :
- persistent resizable main windows
- video confined to preexisting window size

The object was typically already killed, so the thread was leaked.
Also, remove vlc_object_kill, since the thread never checks for the
detach of its own object.
