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.

Fix GCC warning:
asrc_abuffer.c: In function ‘init’:
asrc_abuffer.c:258: warning: passing argument 1 of ‘strtok_r’ discards qualifiers from pointer target type

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.

Also drop obfuscating CHROMA_WIDTH/HEIGHT macros.

More consistent with the original libmpcodecs code, and the name
"unsharpen" was confusing.

The source was natively integrated into libavfilter, with the name
mptestsrc.

This way it's easier for the programmer to look-up for a specific
symbols (e.g. for checking if it's unused).

Fix NULL pointer dereference in case of failed initialization.

The gradfun filter was already integrated natively in libavfilter.
Both filters issue the same output, and have a comparable performance.

Previously both the buffer and buffersink elements were associated to
the "BUFFER" symbol in allfilters.c, so it was not possible to enable
one without the other.

void* pointer arithmetic semantics is undefined, use uint8_t* instead.

Also fix GCC warnings:
defaults.c: In function ‘set_common_formats’:
defaults.c:184: warning: pointer of type ‘void *’ used in arithmetic
defaults.c:189: warning: pointer of type ‘void *’ used in arithmetic
