This allows encoders to set pts and/or duration even if they do not use
CODEC_CAP_DELAY.

The AVOptions based default to threads auto in 2473a45c
works only if avplay does not use custom option handling
for -threads.

For video, mark the first sample in a trun which doesn't have the
sample-is-non-sync-sample flag set as a keyframe.

In particular, the "sample does not depend on other samples" flag
isn't enough to make it a keyframe, since later frames still can
reference frames prior to that one (the flag only says that that
particular frame doesn't depend on other frames).

This fixes bug 215.

This prevents having to sign-extend on 64-bit systems with 32-bit ints,
such as x86-64. Also fixes crashes on systems where we don't do it and
arguments are not in registers, such as Win64 for all weight functions.

Output packet size should match avctx->block_align. The target output packet
size is 1024 bytes.
Before:
mono   - 1024 samples -> 512 bytes
stereo - 2048 samples -> 2048 bytes
After:
mono   - 2048 samples -> 1024 bytes
stereo - 1024 samples -> 1024 bytes

This will allow parsers to export the duration of the current frame being
output, if known, instead of using AVCodecContext.frame_size.

Also, only set bit rate for CBR.

also remove unneeded commented-out full frame data debugging

We now require at least libmp3lame 3.98.3.
lame_encode_buffer_interleaved() still doesn't work for mono, but it does not
"die"; it just expects a stereo interleaved buffer.

it is already set in avcodec_alloc_frame()
