baseparse: Update min/max bitrate before first posting them
...
This avoids posting an initial min-bitrate of G_UINTMAX and max-bitrate
of 0.

baseparse: tune default duration estimate update interval
...
Rather than a fixed default frame count, estimate frame count to aim for
an interval duration depending on fps if available, otherwise use old
fixed default.

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.

audioparsers: baseparse: Be careful to not lose the event ref
...
Don't unref the event if it hasn't been handled, because the caller
assumes it is still valid and might reuse it.
I ran into this problem when transcoding an AVI (with mp3 inside)
to gpp.

baseparse: enhancements for timestamp marked framed formats
...
That is, as such formats allow subclass to extract position from frame,
it is possible to extract duration (if not otherwise provided)
from (near) last frame, and a seek can fairly accurately target the required
position.
Fixes #631389 .

Revert "baseparse: add skip property"
...
This reverts commit b5a3d60363
.
Reverting this for now, since no one really seems to remember why this
property exists or what it could possibly be good for. It seems to have
been in the original mp3parse since the beginning of time and was back-
ported from there.
