	Disable the split function. This should end the mpeg1/2 global header issues.
The split function is essential for -ss to work
Fixes issue1226
If this breaks something please tell me, also if someoen remembers what problem
this originally caused tell me too, i searched but couldnt find it.

3d05c1fbec Make the jump-table section-relative for x86_64 with PIC enabled. 
This allows to get rid of the macho64 specific hack that moves them
to rodata (with worse cache behaviour) and avoids textrels which
e.g. Gentoo does not allow for x86_64 libraries.

e814817b74 Factor mv/ref compare code out. 
This is a hair slower (0.15% maybe) but i really dont want to have the
identical code duplicated 3 times because gcc adds odd threaded jumps with
register reshuffling and register safe/restore.

980bcc554d Unroll main loop so the edge==0 case is seperate. 
This allows many things to be simplified away.
h264 decoder is overall 1% faster with a mbaff sample and
0.1% slower with the cathedral sample, probably because the slow loop
filter code must be loaded into the code cache for each first MB of each
row but isnt used for the following MBs.
