Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
Extensions in AAC USAC can be stored across multiple frames (mainly to keep CBR compliance).
This means that we need to reallocate a buffer when new data is received, accumulate the bitstream data,
and so on until the end of extension flag is signalled and the extension can be decoded.
This is made more complicated by the way in which the AAC channel layout switching is performed.
After decades of evolution, our AAC decoder evolved to double-buffer its entire configuration.
All changes are buffered, verified, and applied, on a per-frame basis if required, in often
random order.
Since we allocate the extension data on heap, this means that if configuration is applied,
in order to avoid double-freeing, we have to keep track of what we've allocated.
It should be noted that extensions which are spread in multiple frames are generally rare,
so an optimization to introduce av_refstruct_realloc() wouldn't generally be useful across the codebase.
Therefore, a copy is good enough for now.
Thanks to Michael Niedermayer for additional fixing.

- 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.

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.
