It is a bit ridiculous to have 34 translations needed for such a small
module...

This ensures we use the installed libvlc(core) run-time, and might
fix some obscure crashes.

Fix #4822 and #4823.

There was only release() before.

As far as I understand, this breaks C++ object scoping. qtu() creates
a temporary anonymous QByteArray from its QString parameter. That array
is destroyed at the end of the expression, thus the return value of
qtu() becomes a dangling pointer.

* Development layer / Image processing / Color space conversion

CFLAGS and LIBS must be tweaked manually to use this.

Not used yet. It should also support H.263

As per the updated specification of December 2010

also fix a memleak in an error path

darwin relied on argv[0] as a fallback to retrieve executable name,
but this can't work anymore as:
- libvlc_new() can be given anything as argc/argv
- libvlc_new() inserts "libvlc" at position 0 anyway

Also use a static boolean if the condition has been signaled
before we start waiting on it: libvlc_MediaPlayerSnapshotTaken event
is serialized with libvlc_video_take_snapshot() so when the function
returns the event already happened.
