also update the multiple inclusion guards in config.h|mak

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

This removes ff_get_ref_perms_string, ff_dprintf_ref and ff_dprintf_link
fro the interface of libavfilter.

of a filter for setting the output timebase, if there is such a link,
rather than always use AV_TIME_BASE_Q.

This fixes configuration for all the filters which do not use the
default config_props for the output link, and do not set explicitely
the timebase.

This is required for allowing a filter to use a time base different
from AV_TIME_BASE_Q, as it was previously assumed.

link rather than avfilter_default_get_video_buffer().

This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for
example if in filterchain there is a pad filter (like in "fifo,pad").

In that case the pad filter will try to write beyond the data of the
allocated buffer, resulting in a crash.
