Use abs(sweep_bps) instead of fabs(). "sweep_bps" is an integer,
and on some compilers this line generates a warning.

In addition to its decoding use, it is the value used for
OPUS_SET_PACKET_LOSS_PERC.

Also makes the CTL bad argument handling more consistent to avoid mistakes
 like that in the future.  Also updates the variable duration docs.

This left FEC disabled on the decoder side for all cases except concatenated
packets. Also fixes a FEC bug in opus_demo (wrong output buffer size
calculation).

Variable duration option renamed to OPUS_SET_EXPERT_FRAME_DURATION,
with new API.
Also moves up the analysis to avoid having to do int->float conversion
on large buffers.

The search is based on minimizing the bitrate increase due to transients
by considering we can reduce the "transient boost" by reducing the frame
size, at the cost of increasing the normal overhead.

Also, the encode+decode mode now produces an output of the same size
as the original.

While this is not making a huge difference it still makes the code
more consistent.

This implements an API used in future encoders to avoid dynalloc doing silly things
on periodic LSB patterns and to reduce the bitrate on near-silence.

This reverts commit 9f407afa.

Also added 3rd clause to "master" COPYING file

- Draft updates
- Updated code to produce and check test vectors
- Making sure that the test vectors pass at all rates as well as for mono and stereo

Undocumented for now

Newly introduced check_encoder_option failed unconditionally instead of only when you used the wrong options.

And vice versa

Also reformat some, but by no means all, of the opus
code for line length and three-character indents.

Renames test_opus to opus_demo and adds the test_opus_api, test_opus_encode, test_opus_decode test programs.

This is achieved by running the encoding process in a loop and
padding when we don't reach the exact rate. It also implements
VBR-with-cap, which means we no longer need to artificially decrease
the SILK bandwidth when it's close to the cap.
