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.

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.
