1d333c1547 avcodec/jpegtables: Unavpriv MJPEG-tables
There are seven MJPEG-tables, five small (1x12, 4x17) and two
not small (2x162). These are all avpriv, despite this not being
worthwhile due to the overhead of exporting a symbol: The total
overhead for each symbol consists of two entries in .dynsym (24B each),
one entry in the importing library's .rela.dyn (24B) and one in .got
(8B) as well as 2x2B for symbol versions and 4B for symbol hashes
in the exporting library; in addition to that, the name of the symbol
is included in both exporting and importing libraries, using 2x210 bytes
in this case.
(The above numbers are for a x64 Elf/Linux/GNU system. Other platforms
will give different numbers.)

a501947a84 avcodec/mjpeg2jpeg_bsf: Remove unnecessary header
libavutil/mem.h is unneeded since 33d18982fa,
the commit that introduced the new packet-based bsf API, because with
this switch the allocations were no longer performed directly, but by
av_new_packet().

None of these symbols should be accessed directly, so declare them as
