lavc: add frame multithreading capability (currently intra only)
Compared to the decoder side, this code is able to change both the
delay and the number of threads seamlessly during encoding. Also
any idle thread can pick up tasks, the strict round robin in order
limit is gone too.

extend log line buffer sizes
The string passed to av_vlog() from libx264's X264_log overflows the 512
byte part_size, truncating x264 parameter output. Double this size
and put it in a #define so it only needs to be changed in one place.

lavu: add av_usleep() function
This function implements a delay using the first available
of the following functions:
- nanosleep()
- usleep()
- Sleep() (Windows)
The conditional #includes in time.c are simplified by including
unistd.h and windows.h whenever they are available rather than
having these lines triggered by specific functions.

To ensure the full range of values is still used, also adjust all uses of this function to loop from 0

The unistd.h header is only needed for the close() declaration.
If this header is not available, the close() declaration may be
provided by another header, e.g. io.h.

The only symbol this file uses from unistd.h is isatty(). By
including the header only when this function is used, the file
can be built on systems without unistd.h (which presumably also
lack isatty).

Add request_frame() which checks the black duration when the end of the

Note that the reported last black video segment duration is not very
accurate, since we still miss the duration information in the video

It's redundant, since the input buffer is passed as a parameter to the
filter_samples() callback, and can lead to stale pointers remaining on
the link.

lavc: remove stats_in from AVCodecContext options table.
Its documentation states that it is allocated/freed by the caller, but
it is declared as an AV_OPT_TYPE_STRING AVOption. Since 367732832faaf1bac4ece37cf7fef8c911e16312 the AVOptions system frees
strings automatically. This can be considered an API break, since it
won't work when the caller doesn't use av_malloc() to allocate the
memory or wants to use the string after closing the codec.
Since there is not much value in this field being an AVOption, the best
solution is to remove it from the options table.

While these defines are not defined by the C standard they are
standardized as X/Open System Interfaces Extension. We use the
appropiate _XOPEN_SOURCE define to make them available. They
seem to be available on all FATE configs since the constants
are used in files where mathematics.h is not included.
