build: check if AS supports the '.func' directive

Not supported by Clang's integrated assembler. Since it just adds
debug information it can safely omitted.
oggenc: Support flushing the muxer

This allows the caller to write all buffered data to disk, allowing
the caller to know at what byte position in the file a certain
packet starts (any packet written after the flush will be located
after that byte position).

huffyuvdec: implement trick

When the joint table does not contain a valid entry, the decoding restarts
from scratch. By implementing the trick of jumping to the 2nd level of the
individual table (and inlining the whole), a speed improvement of 5-10%
is possible.

On a 1000-frames YUV4:2:0 video, before:
362851 decicycles in 422, 262094 runs, 50 skips
182488 decicycles in gray, 262087 runs, 57 skips
Object size: 23584
Overall time: 8.377

After:
346800 decicycles in 422, 262079 runs, 65 skips
168197 decicycles in gray, 262077 runs, 67 skips
Object size: 23188

avfilter/bufferqueue: Increase buffer queue size

Avoid buffer overruns when processing some MOV files with the amerge
filter. Files produced by Adobe Premiere Pro CC have up to one second of audio
not interleaved. With common settings (<= 48kHz) that makes up to 47 frames so
a queue length of 64 makes sense.

Fixes ticket #3510.
