- fixes the test_opus "skip" for stereo
- fixes 6 visual studio compile warnings
- adds several header files to visual studio's include folder

Making sure not to abruptly "de-collapse" the stereo for such transitions

When SILK decided not to use the desired bandwidth, the redundancy
could be encoded at the desired bandwidth rather than at the actual
bandwidth used.

No longer encoding the redundancy flag for SILK since we can infer
redundancy from the length of the frame. Also, we skip encoding the
flag for hybrid mode when we know the decoder will not read it.

Also not fuzzing the mode when it's forced

Adds SILK delay compensation that depends on encode and decode sampling
rate, as well as SILK internal coding rate. This ensures that the SILK
part of Opus is always in sync with the CELT part no matter what the
sampling rates are. It also increases the resampling delay to 1.15 ms
(was previously 0.48 ms).

Simplifies mono/stereo switching in SILK
Fixes a quantization mismatch between encoder and decoder
Constrains the pitch lags in the same way in the encoder and decoder

More assert updates, make the initialization in silk_warped_autocorrelation_FLP more explicit to make tools happy, and allow resetting to auto with OPUS_SET_FORCE_CHANNELS.

We now reset the CELT state when swithing to hybrid and we "drain"
the CELT MDCT overlap when switching away from hybrid.

Add the noreturn attribute on the assert functions to aid static analysis, improve test_repacketizer error handling, and silence 19 clang static analysis errors with additional assertions.

Gets rid of some more glitches caused by the decoder resampler

The redundancy_bytes<0 test always fails because of the ec_tell(&dec)+29 test above.

Delaying stereo->mono switching decisions so that SILK can do a smooth
downmix. Also, wrote proper float/fixed code for the hybrid variable
stereo collapse, including a smooth downmix for stereo<->mono switching

Fix bug in the OPUS_GET_APPLICATION_REQUEST ctl and also add a bunch of set ctl range checking and improve encoder/decoder error code consistency.

Also some MSVC build fixes

The parameters for public API calls are already documented
in opus_multistream.h. It's better not to have separate
copies of those comments in the implementation.

Correct member comments copied from the non-multistream api,
and document the remaining undocumented members. Still very
rough.
