487fef2dcc asf: update seek test reference
This updates the seek test reference to match de11ee9.  Before this
change, most of the seeks requested positions before the supposed
start of the file (the preroll time), resulting in the first packet
being returned.  With the preroll subtracted, some of these seeks
will land within the file and some beyond the end, thus returning
a different set of packets.

dc6fdad5dc Add missed APIchanges and changelog entries
Add an APIchanges entry for the av_pkt_dump2 and av_pkt_dump_log2
functions, and a changelog entry for the apple http live streaming
protocol handler.

Since neither of them got a minor bump at commit time, but were
applied before the jv demuxer, they all can be considered added
in this minor version.

79414257e2 mathops: fix MULL() when the compiler does not inline the function.
If the function is not inlined, an immmediate cannot be used for the

c76374c6db Use AVERROR_EXIT with url_interrupt_cb.
Functions interrupted by url_interrupt_cb should not be restarted.
Therefore using AVERROR(EINTR) was wrong, as it did not allow to distinguish
when the underlying system call was interrupted and actually needed to be
restarted.

This fixes roundup issues 2657 and 2659 (ffplay not exiting for streamed
content).

323e6fead0 ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.
This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.
