add --snapshot-prefix and --snapshot-sequential options. --snapshot-prefix lets you choose the filename's prefix (default it "vlcsnap-"). --snapshot-sequential numbers the snapshot starting with 1 and incrementing every time.

* another patch for ffmpeg, so make up a new ffmpeg patch-file and ditch the previous configure-specific one

It would be nice if someone with more x264-knowledge could review this.

* yet another patch for ffmpeg: its configure script doesn't recognise that (at least on OSX) variables' names are case-sensitive

No need for a separate directory for 1 file

include/vlc/mediacontrol.h, src/control/mediacontrol_audio_video.c: implement get_/set_rate and get_/set_fullscreen

linux also (I do no quite know the current status, but it works for me this way at the moment).

* add "make nice" in modules to call ./compile

* malloc with NULL check
* file extension check
* check if a demux was forced
* try peeking, and check what we poke
* init standard demuxer fields
* create packetizers

bindings/mediacontrol-python/vlcwrapper.py: make the tree() method return a string rather than print it.
