Renamed for consistency. Also, since print_int() and print_str() are
already defined as macros, the long name version is preferred.

Having a string callback is much more simpler than a variable args
one for writers to deal with, especially when dealing with escaping.

This patch also introduces a local fast_asprintf() function which is
similar to av_asprintf() but avoids reallocating at each print (leading
to a performance issue).

Speed: from 3.9x to 9.6x speed improvement over C, and some small
(up to 15%) speed improvements over existing MMX code (particularly
for bigger filters).

I dont know on which system the prior check failed but an advanced
linker on some platform might have optimized func() out as unreachable.

This fixes overwriting x264 preset settings for flags2 based options.
See https://ffmpeg.org/trac/ffmpeg/ticket/448

This avoid retrying to read ASF index in files for every
attempt to seek. This makes a big difference to protocols
with slow seeking (for example http)

These changes were forgotten in commits:
  lavfi: simplify signature for avfilter_get_audio_buffer() and friends
  (commit 2c031741)
and
  lavfi: consistently use int for sample_rate in AVFilterLink and AVFilterBufferRefAudioProps

This fixes https://ffmpeg.org/trac/ffmpeg/ticket/448 - at least for
rc_lookahead. A similar problem still exists for the flags2 based
options.

Also consistent with AVCodecContext.sample_rate. Simplify/avoid
pointless type checks and conversions.

Breaks audio API/ABI.

The additional parameters were never used and are complicating the
function interface. Also, they were inconsistent with the way the
video API works.

So this assumes that a requested samples buffer will have *always* the
format specified in the requested link.

This breaks audio filtering API and ABI.
