This fixes a crash

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

These changes were forgotten in commits:
  lavfi: simplify signature for avfilter_get_audio_buffer() and friends
  (commit 2c0317419b)
and
  lavfi: consistently use int for sample_rate in AVFilterLink and AVFilterBufferRefAudioProps
  (commit 4381bddc9f)

Also consistent with AVCodecContext.sample_rate. Simplify/avoid
pointless type checks and conversions.

Breaks audio API/ABI.

The additional parameters were never used and are complicating the
function interface. Also, they were inconsistent with the way the
video API works.

So this assumes that a requested samples buffer will have *always* the
format specified in the requested link.

This breaks audio filtering API and ABI.

Some fixes by Stefano.

It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.

This is done in order to clarify the non-video-specific nature of the
buffersink code, as the result of the video/audio API unification of
the previous commit, and for improving overall consistency.

The new API is more generic (no distinction between audio/video for
pulling frames), and avoids code duplication.

A backward compatibility layer is kept for avoiding tools ABI breaks
(only for the video binary interface, audio interface was never used
in the tools).

the basetime argument also enables useage of pts instead of time()

This makes it easier to refer to filters where things are seperated by spaces.

The file is going to contain the amovie source, so give it a less
specific name.

Reduce code duplication.

This is required for the pending lavfi indev extension, also
consistent with the video buffer sink.

Allow factorization for the pending work on the audio movie source.

Add the sar option. Useful for debugging/testing purposes.

strsep() is not POSIX compliant, and thus not supported on some platform.

The previous default value 0x0 was not good, since it is not even
valid.

In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.

The delogo filter has been natively integrated into libavfilter,
simplify.

The ported filter supports named option parsing and more YUV formats.

Allow to cache more than one frame (e.g. for filters which return
more than one frame when avfilter_request_frame() is called on them),
and do not discard previously cached frames when a new one is added.
