Otherwise, the user requested priority of packet side data will be ignored.
For this, move the relevant functions to decode.c, as they need access to an
AVCodecContext.

This commit will cause TIFF files to store their tags in the EXIF
struct so tags such as orientation can be transfered to other formats
(such as PNG) in a way that doesn't corrupt the IFD.

This makes the enum TiffTypes public by moving it to the public header
exif.h and renaming it to AVTiffDataType, as well as adding an AV_
prefix in front of each of the entry names. This allows callers to use
enum AVTiffDataType without pulling in all of tiff_common.h, as that
header is not public.

This is simpler than calling avcodec_find_decoder().
Notice that av_codec_init_static() has already been called
by the time we reach these decoders' init functions,
so it is not necessary to call avcodec_find_decoder()
for it (which doesn't do anything for the mjpeg decoder
anyway).

There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.

Instead store all the strings in one continugous string
(with internal \0) and use offsets to access the actual
substrings. This replaces the pointers to the strings
and therefore avoids relocations (and on x64, it actually
shrinks TiffGeoTagNameType by reusing padding to store
the offset field).
This saves 720B of .data.rel.ro and 1080B of .rela.dyn
(containing the relocation records) here while increasing
.rodata by 384B.

For unknown geokey values, get_geokey_val() returns
"Unknown-%d" with val being used for %d. This string
is allocated and therefore all the known geokey values
(static strings) are strdup'ed. In case this fails
it is either ignored or treated as "Unknown-%d".
(Furthermore it is possible to call av_strdup(NULL),
although this is not documented to be legal.)
This commit changes this by only returning the static strings
in get_geokey_val(); the unknown handling and strdup'ing
is moved out of it.

The function signature for bytestream2_seek is (gb, offset, whence);
Before this patch, the code passed (gb, SEEK_SET, offset), which is
incorrect.

Codecs that can read/write ICC profiles deserve a special capability so
the common logic in encode.c/decode.c can decide whether or not there
needs to be any special handling for ICC profiles. The motivation here
is to be able to use it to decide whether or not an ICC profile needs to
be generated in the encode path, but it might as well get added to
decoders as well for purely informative reasons.
It's not entirely clear to me whether the "thp" and "smvjpeg" variants
of "mjpeg" should have this capability set or not, given that the code
technically supports it but I somehow doubt these files may contain
them. In either case, this cap is purely informative for decoders so it
doesn't matter too much either way.
It's also not entirely clear whether the "amv" encoder should signal ICC
profile support, but again erring on the side of caution, we probably
*shouldn't* be generating (and encoding!) ICC profiles for this type of
media file.

and remove FF_CODEC_CAP_INIT_THREADSAFE
All our native codecs are already init-threadsafe
(only wrappers for external libraries and hwaccels
are typically not marked as init-threadsafe yet),
so it is only natural for this to also be the default state.

This is possible, because every given FFCodec has to implement
exactly one of these. Doing so decreases sizeof(FFCodec) and
therefore decreases the size of the binary.
Notice that in case of position-independent code the decrease
is in .data.rel.ro, so that this translates to decreased
memory consumption.
