Ongoing fixes and improvements, transient suppressor is gone. Also,
dropping isac because it doesn't seem to be useful, and is just build
system deadweight now.
Upstream references:
Version: 131.0.6778.200
WebRTC: 79aff54b0fa9238ce3518dd9eaf9610cd6f22e82
Chromium: 2a19506ad24af755f2a215a4c61f775393e0db42
Some API deprecation -- ExperimentalAgc and ExperimentalNs are gone.
We're continuing to carry iSAC even though it's gone upstream, but maybe
we'll want to drop that soon.
Since we cannot rely on the API to be stable upstream, let's start
making the pkg-config, library, and include dir have a version suffix.
This will allow different downstream projects depending on us to
independently switch versions without packagers having to jump through
hoops.
Corresponds to upstream commit 524e9b043e7e86fd72353b987c9d5f6a1ebf83e1
