The macro can be used to define consistently the internal class of a
filter, save some typing and factorize.

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.

This reduces the dependency on unistd.h which is not available
on all systems.

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.

This reverts commit a2b186a1.

The defines were present for several years, removing
them without a version bump may break API.
(Fixes MPlayer compilation.)

To ensure the full range of values is still used, also adjust all uses of this function to loop from 0
instead of 1. This way only 60.00 is added and nothing lost.

-same_quant is not designed to convert between quantizer scales, AFAIK.

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).

and CODEC_ID_TEXT with the timestamps in the packet fields.

The list was set to avfilter_all_channel_layouts,
which is really all common channel layouts.
Not setting it leaves an empty list,
which now means really all.
