The LOAS variant seems to have three different subvariants itself,
only one of them is implemented as my two samples happen to be
using that one.
The sample rate is not always reported correctly, as the "main"
sample rate is apparently sometimes half what it should be (both
of my samples report 24000 Hz there), and there are two other
parts of the subvariant with different sampling rates. One of them
is parsed, but not the other, as it's located after some other
large amount of variable data that needs parsing first, and there
seems to be a LOT of it, which is useless for our needs here.
This ends up being rather inconsequential, as ffdec_aac_latm,
which is the only decoder that can decode such streams, does not
need the sample rate on the caps anyway.

Some possible FIXMEs remaining in the audio parser getcaps functions.
Also add a format flag to signal baseparse that subclass/format can provide
(parsed) timestamp rather than an estimated one. In particular, such "strong"
timestamp then allows to e.g. determine duration.
Seekability, like duration, etc is unlikely to change (frequently), and
the default assumption covers most cases, so let subclass set when needed.
At the same time, allow subclass to indicate if it has seek-metadata (table)
available, and possibly have it provide an average bitrate.
This patch adds the get_frame_overhead() vfunc so that baseparse can
accurately calculate the min/avg/max bitrates for aacparse.
Note: The bitrate was being incorrectly calculated for ADTS streams
(it's not in the header as the code suggests).
Because config.h defines __MSVCRT_VERSION__, which should be defined
before inclusion of any system header.
Also fixes mpegdemux Makefile.am LIBADD typo.
Fixes#606665
