  avserver: do not use a static string as a default for a string option

See: 19c41c6dMerged-by: Michael Niedermayer <michaelni@gmx.at>

Changes since v1 of the patch:
- enable option by default
- add documentation
- move up PTS override code after PES header parsing, to ensure we use the
  last PCR before the first packet of the teletext PES packet.

The option overrides teletext packet PTS and DTS values with the timestamps
calculated from the PCR of the first program which the teletext stream is part
of and is not discarded.

Using the same teletext PID for multiple programs is possible, therefore we
need some kind of heuristics to know which program PCR we should synchronize
to. Using the first non-discarded PCR pid among the programs of the teletext
stream seemed like a good choice.

The patch does not do PCR interpolation to estimate the PCR of the teltetext
packet, it just uses the last PCR of the program, which may cause a slight
error (0.1 sec) in the teletext packet pts-es.

Based on a patch by Reimar Döffinger.

Simplifies check and should fix lumi+vari warning
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This will allow using the same code when one filter can be inserted both
on input and output.

If any samples are still buffered when request_frame returns EOF, they
won't be returned currently.

Incidentally also remove a warning.

Some code paths can call it with invalid length.

CC: libav-stable@libav.org

'filter' is too generic, since the functions in question deal with
several filters.

Also add const qualifiers to those variables.

This function should never modify the filter.
