edc942202b lavf: fix signed overflow in avformat_find_stream_info() 
On the first iteration through this code, last_dts is always
INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in
an invalid manner.  Although the result is only used if the
input values are valid, performing the subtraction is still
not allowed in a strict environment.

f7be632cbd vp8: fix signed overflows 
In addition to avoiding undefined behaviour, an unsigned type
makes more sense for packing multiple 8-bit values.

4c5cdb493c 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.

09a288476f 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.
