Alexander Larsson 5ef114ba42 Switch from sending png frames to our own encoding
This is based on the rolling hashes code from
http://cgit.freedesktop.org/~krh/weston/log/?h=remote

It works by incrementally calculating hashes for every 32x32 block
in each frame sent, and then refering back to such blocks when
encoding the next frame. This means we detect when a block matches
an existing block in the previous frame in a different position.
This is great for detecting scrolling, which we need now that
the gdk level scrolling is neutered.
