ac6eab1496 put_bits: fix invalid shift by 32 in flush_put_bits() 
If flush_put_bits() is called when the 32-bit buffer is empty,
e.g. after writing a multiple of 32 bits, and invalid shift by
32 is performed.  Since flush_put_bits() is called infrequently,
this additional check should have negligible performance impact.

14c21c1ff5 H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock 
This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.

eaa21b6870 H264: hotfix for speedloss on frame threading and h264 files with slices. 
This fix is not ideal as it still limits the multithreading on field pictures
to the 2nd field only.
Ill try to fix it properly to allow both fields to decode concurrently but this
needs more work.
