Fix scene filter when using source dimensions as output dimensions. Allow outputing to all image types supported by VLC.

That being noted, I would advocate ditching all RTSP control connection
timeouts from our live555 plugins. Looking at strace, live555 waits
forever in the middle of receiving RTSP messages anyway.

In principle, isalpha() depends on the locale. As for directory
traversal, we should either add a boolean, or fix it manually in the
caller (on a case-by-case basis).

 - remove practically never used encodings (UTF-32, ARMSCII, Latin-4...),
 - remove duplicates and/or subsets (UCS, Latin-1, TIS620...) that I know of,
 - provide human-readable names (fixes #2571).

1/ We have so much of those requests on the forum.
2/ It doesn't change any string.
3/ Change is self-contained.

That happened when seeking during the first second of playback.

Never disable Stop
Disable stop when no input

Don't mix booleans and strings (as non empty strings evaluate to true).

This kills 100 wakeups per seconds.

In principle, this avoids a possible event loss. I am not sure if the
NAV PCI handling is thread-safe here (but it's no worse than before).

We may want to factor some of that marshalling into libvlc later on.

This solves a potential event loss for close events
(especially with the RC interface)
