Against further dynamic linker namespace pollution.

Also optimize it away where applicable.

(see comments)

The ES output never calls FrameNext on non-video tracks.

Pruning by time was removed a while ago, but
pruning by segment number only can't work for pruning the whole
playlist as that number can be inconsistent across representations
and streams/adaptation sets.

Pruning by number should only occur merging/at representations level.

was not working with live streams as not starting from zero

And use targetduration hint for scheduling HLS updates

segment could become unavailable before we could fully download it.

In case of memory error, the functions will abort (table macros). Even
if it did not, callback deletion would later abort failing to find the
callback instead. (The API could be redesigned not to require memory
allocation if necessary.)

In case of nonexistent variable, log an error and fail safe as before.
This lead to deadlocks of misbehaviours as before - no changes here.

If the callback does not exist, the program aborts anyway, so the
error value was mostly useless, and indeed always ignored.

The function can only fail if the named variable does not exist. The
only case where the error was actually checked was after another check
that the variable exists (Old RC).

DecoderProcess() can only be used with the decoder, not the packetizer.
Inline DecoderFlush() to fix the issue.

Fixes duplicate menu selector images with some HDMV discs.

If an error occurs on write, set an error flag (all future Play will drop the
block). If an interrupt finish, cancel the error state and try again.

they are ready for the requested modes.
