7f969c0eff Ensure that an RTP audio level of 127 represents digital silence. 
To quote rfc6464:
  The audio level for digital silence -- for a muted audio source, for
  example -- MUST be represented as 127 (-127 dBov), regardless of the
  dynamic range of the encoded audio format.

The behavior in webrtc is correct that digital silence is represented
with 127, but it is also possible to get a value of 127 for not quite
digitally silent audio buffer (as in, not strictly 0s).

928146f546 Removing all external access to the integer sample data in AudioBuffer 
This CL removes all external access to the integer sample data in the
AudioBuffer class. It also removes the API in AudioBuffer that provides this.

The purpose of this is to pave the way for removing the sample
duplicating and implicit conversions between integer and floating point
sample formats which is done inside the AudioBuffer.

a4d873786f Format almost everything. 
This CL was generated by running

git ls-files | grep -P "(\.h|\.cc)$" | grep -v 'sdk/' | grep -v 'rtc_base/ssl_' | \

grep -v 'spl_inl_mips.h' | grep -v 'data_size_unittest.cc' | grep -v 'timestamp_unittest.cc' \
| xargs clang-format -i ; git cl format

Most of these changes are clang-format grouping and reordering includes
differently.

14696c23d9 [Cleanup] Remove our own definition of M_PI. 
* This is too brittle and might clash with MSVC's M_PI. See [1].
* We only used it once (in a unit test).
* We shouldn't use PI anyway [2].

Instead, pull it from <cmath> with _USE_MATH_DEFINES,
like it's already done in the code base.

65c392265f Move some more numeric utility code from rtc_base/ to rtc_base/numerics/ 
Specifically, I'm moving

  histogram_percentile_counter.h
  mathutils.h
  mod_ops.h
  moving_max_counter.h

They shouldn't be part of the API, and moving them to an appropriate
subdirectory of rtc_base/ is a good way to keep track of that.

92ea95e34a Fixing WebRTC after moving from src/webrtc to src/ 
In https://webrtc-review.googlesource.com/c/src/+/1560 we moved WebRTC
from src/webrtc to src/ (in order to preserve an healthy git history).
This CL takes care of fixing header guards, #include paths, etc...
