Fix warning:
ffplay.c: At top level:
ffplay.c:3027: warning: missing braces around initializer
ffplay.c:3027: warning: (near initialization for ‘options[53].u’)

Fix crash if ic->pb is NULL and ic->pb->error is evaluated. This
happens for example with: ffplay photo.jpeg.

This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.
The "buf" pointer needs to be overwritten since otherwise the CRC check fails.

draw_slice() checks that the fade factor is < 65536 and only
calculates the fade if so. But the fade factor is clipped in
end_frame() by av_clip_uint16() to 65535, so the fade is calculated
for every frame.  This patch alters the check so that it compares with
< 65535 (UINT16_MAX).

draw_slice() checks that planes 0 and 1 of AVFilterBufferRef's data
are not NULL before manipulating planes 1 and 2. This patch makes the
check against planes 1 and 2. More senseful and possibly more robust.

and use in scale_coefficients() for the floating-point AC-3 encoder.

This updates the seek test reference to match de11ee90.  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.

right now swab is defined in libavfilter/libmpcodecs/mpbswap.h
this breaks mingw32 cross compiles. since it its not used, it should be
removed. alternatively swab has to be added to HAVE_LIST in configure.

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.
