Improve motion compensation for ARM: * Use less registers in the simple copy routines -> less stack usage. * Save a few instructions in constants + jumptable handling. * ARM6 optimisations. Unfortunately we can't just use uhadd8 because that rounds down, while we have to round up.

Bring libmpeg2 portions that we use up to date with the latest libmpeg2 CVS. Fix up some file headers and add a revision history to the libmpeg2 files detailing to which CVS file revisions things were synced. This makes it easier to start in the right place by hand in the future. Hopefully no mistakes and everything works. :-)

mpeg2dec in mpegplayer: Do a little code slashing and organizing. Much more to come I think.

optimized motion compensation for ARM from the mplayer-w100 project. Elefants Dream plays back 2.3fps faster on the Gigabeat
