Reland "Fixes to the the activity flag that is passed to Silk so it represents the final activity flag used in the DTX decision"

This flag was modified after calling the Silk encoder function. This commit corrects that behavior by introducing those modifications before calling the Silk encoder.

The data pointer could be null in the case of DTX or packet loss.

Copy the previous analysis data instead of flagging as invalid

The previous code would go out of sync in those cases.

logE[b] can end up slightly larger than tonal->highE[b] due to rounding

Thanks to Dmitriy for reporting this.

frame diration is only handled at the Opus layer. There's no change
in behaviour, just less puzzling code.

Thanks to Dmitriy <dmilvdv@gmail.com> for reporting this.

Without that change, a very long (> 682 ms) illegal packet could trigger
a wrap-around in the test and be accepted as valid.

Only 16-bit architectures (e.g. TI C5x) were affected.

clang -Wcast-align warnings with ambisonics enabled
clang -Wnull-pointer-arithmetic warnings in test_opus_api.c
gcc -Wimplicit-fallthrough warnings on arm
msvc warning C4244 in celt_encoder.c with fixed point

Causes a warning with -Wnull-pointer-arithmetic and the code wasn't doing
anything anyway (the ctl call ignores NULLs)

This gets rid of false positives in static analysis
(see https://trac.webkit.org/changeset/232236/webkit)

Fixes test_opus_projection failure under ubsan, due to clz(0).

Don't assume that frames larger than 20 ms save any overhead compared to 20 ms.

The bug was triggered because f982b84d started using prefill for
SILK bandwidth changes, which reinitialized the encoder state and
prevented the variable lowpass from working properly. To fix the problem,
we preserve the sampling rate and variable low-pass when prefilling.
