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.)

6eae9c1d39 avcodec/jpegtables: Move ff_mjpeg_build_huffman_codes to mjpegenc_common
Since g2meet.c doesn't use it any more, only encoders use it and
the place for their common code is mjpegenc_common.c.

abf1c058d1 msvc: Properly specify dllexport for data symbols shared across dll boundaries
We currently only have exported data symbols within libavcodec, but
the concept is easy to extend to other libraries if necessary.
The attribute declaration needs to be in a private header though,
since we can't use CONFIG_SHARED in public installed headers.
