cb668476ab motion_est: make MotionExtContext.map_generation unsigned 
The way this value is used, it should be an unsigned type.

is relied upon.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

2d603902f3 Reduce the size of the bidir refine hashtable from 4096 to 256 and 
change the hash function to something more sane and simple.
about 1/3 faster, no meassureable change in psnr or size and i gues
its even same md5 with my test file but i forgot testing that.

2f16af0667 skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome)
