8b19ae0761 crc: fix signed overflow 
This fixes a signed overflow from i << 24 when i == 255 by
making i unsigned.  The result of the shift is already
assigned to an variable of unsigned type.

f5646a325b avconv: always print stats with AV_LOG_INFO 
It's now possible to disable printing stats during encoding with
-nostats, so there's no reason to print them differently depending on
whether it's last report or not.

a31e9f68a4 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.

bb59156606 vp8: fix signed overflows 
In addition to avoiding undefined behaviour, an unsigned type
makes more sense for packing multiple 8-bit values.

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.

2c6cf13940 wavpack: Reset internal state on corrupted blocks 
wavpack_decode_block() supposes that it is called back with the exact
same buffer unless it has returned with an error. With multi-channels
files, wavpack_decode_frame() was breaking this assumption.

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.
