This is pretty straightforward, although there are two weird issues.
The current encoder has two bugs in the yuv conversion. First of all
it switches red and blue, due to something of an endianness issue. We
keep this behavior by switching red and blue. Maybe we want to
change this in the new protocol version since switching this may
cause jpeg compression to be worse.
Secondly, the old coder/decoder did rgb to/from yuv420 wrongly for
jpeg, not using the "full scale" version of Y that is used in jpeg,
but the other one where y goes from 16 to 235. (See jpeg/jfif
reference on http://en.wikipedia.org/wiki/YCbCr for details.)
The new decoder uses the full range in order to get better quality,
which means old encoders will show slightly darker images.
This completely removes all ffmpeg usage in the client
Now we can send commands from the server to the client
to destroy surfaces (right now just the primary surface)
Needed for offscreens support)
Another patch`s on the way.

Screen now have to modes locked and unlocked.
In unlocked mode, the application can change screen size and so
reduce resolution changing. The application can also choose to
change window size while not in full screen mode.
In locked mode the application must ewtain locker screen size
setting.
The process loop is responsible for: 1) waiting for events 2) timers 3) events queue for
actions that should be performed in the context of the thread and are pushed from other threads.
The benefits:
1) remove duplicity: till now, there was one implementaion of events loop for the channels and
another one for the main thread.
2) timers can be executed on each thread and not only on the main thread.
3) events can be pushed to each thread and not only to the main thread.
In this commit, only the main thread was modified to use the new process loop.
