This commit switches avidec to use the new metadata API exposed by
the previous commit instead of relying on the existing avipriv_ function
exposed by lavc.

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.

avio_seek() never supported SEEK_END and returned AVERROR(EINVAL) when
specified, so the later check "(whence != SEEK_END || force)" was always true.
This also means that AVSEEK_FORCE had no effect since 7a6fe01f99, that is 15
years ago. Rather than changing behaviour, let's document instead that the flag
has no effect.
Also fixed other commit 41ed7ab45f which confused ORing / passing AVSEEK_FORCE
and AVSEEK_SIZE in the docs.

The array is only ever needed for streams where each sample entry may have a
different value. Given that for non animated HEIF there's a single value that
applies to the image, use the field defined for that.

Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.

In general, a provider code corresponds to a company/organization, and
the name should be that of the company, not of a given feature.
The feature is signalled in the "provider oriented code".
The exception is HDR Vivid, where the code 0x0004 indicates the HDR Vivid
feature itself rather than CUVA (China UHD Video Industry Alliance),
according to the UHD World Associations 'HDR Video Technology Part 2-1
Application Guide to System Integration' document.

The check to return on EOF should not be inside a block that will not be entered after reaching EOF.

- proper pts for packets. leaving it blank leaves it up for guessing,
but the guess doesn't take seeking into account, causing weirdness.
- clamp to 0 when seeking to negative ts. libopenmpt docs are unclear on
this but not doing this causes an immediate EOF when seeking backwards
to the beginning in mpv.
- only set song duration and packet pts when they are non-negative and
in int64 range. NaNs count as out of range. this isn't a fix for any
specific issue but might be helpful still, and shouldn't break
anything.
Allows to output LRC with more precision than standard centiseconds.
Time base is determined by number of requested digits.

Apparently files with milliseconds exist in the wild. And since it cost
nothing to support arbitrary number of digits, extend format to support
that.
Depending on number of digits, the time base of fractional part is
changing. Most LRCs use 2 digits and centiseconds base, but subs with 3
digits and miliseconds exist too.
Set internal time base to AV_TIME_BASE, which in parcitice allows to
hold microseconds with 6 digits. Totally artificial, but who knows maybe
someone wants that.
