Fixes a warning from PVS-Studio. This was a cut-and-paste error
from the stanza above and had no effect.

Put the colon ':' before the continuation dots like all the

The regression was introduced in 783ad767
by changes to celt_fir() that make it no longer in-place.

The masking term was previously completely broken (even in 1.1). The
bandwidth detection relies mostly on the noise floor and can only use
masking to cut one extra band. The 12-24 kHz energy is now normalized properly
but uses a higher noise floor due to the leakage in the resampler. Bandwidth
detection is still mostly useless at identifying SWB speech (it usually says
FB).

Based on two dense layers with a GRU layer in the middle

SILK was being allocated too few bits for stereo hybrid, often resulting
in forced narrowing of the width. We now allocate more bits to SILK
and reduce the threshold for narrowing. This improves quality enough that
the bitrate threshold for switching to SILK can be increased to 44 kb/s.

Make these consistent with the other optimization file
sets which use a suffix to indicate the extension they
use.

Distinguish source files for the SSE 4.1 instruction
set extension consistently by their filename. This makes
it easier to check the correct flags are being set at
build time.

some SSE optimizations were using an instruction sequence that required
128-bit alignment, even though this is not always guaranteed. The error
was in handling a 64-bit entity; made the same macro changes that had
been done previously for 32-bit entities.

|frame_size_enum| in tests/test_opus_encode.cl:117 is flagged as potentially
uninitialized but get_frame_size_enum() will fail anyway if a valid value is
not found.

Migrating opus-codec.org to a static site generator inserted
a redirect into the download path, which the actual testvectors
at https://opus-codec.org/static/testvectors/opus_testvectors.tar.gz.

Add the -L option to the suggested curl invocation so the redirect
is followed to download the actual resource. Without this one
gets the html redirection fallback page.

The new detector for SWB vs FB is unreliable due to the hack
that was required to get 24 kHz analysis working. We're now err
on the side of FB just to make sure.

Uniform layout is easier for external tools to parse,
especially maintaining one source file per line.

Both versions of silk/tables_NLSF_CB had symbols
named silk_NLSF_CB1_Wght_Q9 which causes problems
if both files are build as part of the same
compilation unit. Rename the wideband version
to include a 'WB' string to avoid the conflict.
