avisynth: Exit gracefully when trying to serve video from v2.5.8.

'Fixes' ticket #2526 insofar as it stops 2.5.8 from crashing and
tells the user to upgrade to 2.6 if they want to make video input
work. A real solution to #2526 would be to get video input from
2.5.8 to work right.

avcodec/options: Drop deprecation warning suppression macros

The options table is used in tools built by the host compiler and the
deprecation macros pull in bits that are not safe to use if host and
target compiler differ.

mpegts: add fix_teletext_pts mpegts demuxer option

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.

mpegts: Make discard_pid() faster for single-program streams

When a stream contains a single program, there's no point in doing a
PID -> program lookup. Normally the one and only program isn't disabled,
so no packets should be discarded.

mpegts: Remove one memcpy per packet

This was being performed to ensure that a complete packet was held in
contiguous memory, prior to parsing the packet. However, the source buffer
is typically large enough that the packet was already contiguous, so it is
beneficial to return the packet by reference in most cases.

avio: Add an internal function for reading without copying

As long as there is enough contiguous data in the avio buffer,

vdpau: deprecate bitstream buffers within the hardware context

The bitstream buffers are now private and freed by libavcodec. For

avconv: support -t as an input option.

It limits the duration of the data read from a given input.

avconv: make input -ss accurate when transcoding

Insert (a)trim filters on the corresponding inputs, so the extra frames
are decoded and discarded.

avconv: distinguish between -ss 0 and -ss not being used

Using -ss 0 to drop frames with negative timestamps is a perfectly valid
use case.

avconv: insert extra filters in the same way for both graph inputs and outputs

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

lavfi/fifo: fix flushing when using request_samples

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