adcb8392c9 mjpeg: Split off bits shared by MJPEG and LJPEG encoders
This obviates a dependency of the LJPEG encoder on mpegvideo.

253d0be6a1 pgssubdec: handle more complex PGS scenarios
Add ability to handle multiple palettes and objects simultaneously.
Each simultaneous object is given its own AVSubtitleRect.
Note that there can be up to 64 currently valid objects, but only
2 at any one time can be "presented".

7b0c7c9163 arm: Detect 32 bit cpu features on ARMv8 when running on a 64 bit kernel
When running on a 64 bit kernel, /proc/cpuinfo lists different
optional features than on 32 bit kernels (because some of them
are mandatory in the 64 bit implemenations).

The kernel does list the old features properly if they are queried
via /proc/self/auxv though - however this file is not always readable
(e.g. on most android systems). The getauxval function could also
provide the same info as /proc/self/auxv even if this file isn't
readable, but this function is not always available (and thus would
need to be loaded with dlsym for compatibility with older android
versions).

The android cpufeatures library does this slightly differently,
by assuming that these are available if the "CPU architecture"
line is >= 8, see [1] for details.

It has been suggested to include the old, non-optional features in
/proc/cpuinfo as well, but that suggested patch never was merged.
See [2] for the discussion around this suggestion.

3f4edf0125 dump_stream: print the timebase as is, do not reduce it
It makes more sense to print the timebase exactly as it is set. Also,
this avoids a divide by zero when av_dump_format() is called on a format
context before writing the header.
