Introduce new small header-only targets in system_wrappers:
:cpu_features_api
:field_trial_api
:metrics_api
to untangle and optimize dependencies but still satisfy GN check.
In webrtc/p2p, previously uncovered header "base/fakecandidatepair.h"
is added to :p2p_test_utils target.
Refactor system_wrappers so 'rtc_p2p' can depend on only
system_wrappers:field_trial_api instead of all of system_wrappers
(which led to a breakage in Chromium that called for the revert of
https://codereview.webrtc.org/2735583002).

Before this CL, we would negotiate:
- No crypto suites for data m= sections.
- A full set for audio m= sections.
- The full set, minus SRTP_AES128_CM_SHA1_32 for video m= sections.
However, this doesn't make sense with BUNDLE, since any DTLS
association could end up being used for any type of media. If
video is "bundled on" the audio transport (which is typical), it
will actually end up using SRTP_AES128_CM_SHA1_32.
So, this CL moves the responsibility of deciding SRTP crypto suites out
of BaseChannel and into DtlsTransport. The only two possibilities are
now "normal set" or "normal set + GCM", if enabled by the PC factory
options.
This fixes an issue (see linked bug) that was occurring when audio/video
were "bundled onto" the data transport. Since the data transport
wasn't negotiating any SRTP crypto suites, none were available to use
for audio/video, so the application would get black video/no audio.
This CL doesn't affect the SDES SRTP crypto suite negotiation;
it only affects the negotiation in the DLTS handshake, through
the use_srtp extension.

When SSRCs aren't signaled, an SSRC of 0 is used internally to mean
"the default receive stream". But this wasn't working with the
implementation of GetRtpReceiveParameters in the audio/video
engines. This was breaking RtpReceiver.GetParameters in this situation,
as well as the new getStats implementation (which relies on
GetParameters).
The new implementation will fail if *no* default receive stream is
configured (meaning no default sink is set), and otherwise will return
a default RtpEncodingParameters (later it will be filled with relevant
SDP parameters as they're implemented).

obvious, WindowCapturerWin should not return Result::SUCCESS with an empty

This issue was original introduced into the code base in change
https://codereview.webrtc.org/1988783003/.
I am also considering whether we should move the
previous_size_ = frame->size();
window_size_map_[window_] = previous_size_;

I would prefer to keep it as small as possible.

Documenting that the observer can safely be destroyed after Close has
been called, because it ensures no more callbacks will be invoked. Just
like in JavaScript land, where no more events will be fired after
"close" is called.
This is already covered by unit tests.

The key change of this CL is to merge ScreenCapturerWinDirectx::frames_ and
contexts_ into a new DxgiFrame class. So consumers of DxgiDuplicateController
does not need to maintain two objects. DxgiDuplicateController::Duplicate*()
functions are also updated to accept DxgiFrame parameter instead of
SharedDesktopFrame + Context. The advantages of this change are,
1. Once the screen resolution changes or an existing monitor has been removed,
DxgiFrame can automatically reset the frame without needing to return a capture
failure.
2. Remove public APIs of DxgiDuplicatorController. Some public APIs are not
needed anymore, i.e. consumers of DxgiDuplicatorController do not need to take
care about these internal states anymore. It also helps to remove several lock
acquiements.
3. Reduce the complexity of ScreenCapturerWinDirectx.
But the disadvantage is, instead of a boolean value,
DxgiDuplicateController::Duplicate*() now return an enumeration. Clients need to
use the enumeration to decide whether the error can be recovered or not.
This change also removes a duplicating logic in ScreenCapturerWinDirectx. i.e.
ResolutionChangeDetector, DxgiDuplicateController now takes care of the screen
resolution changes.
I have verified the scenarios with and without SharedMemoryFactory, also the
Desktop capture API example. So far no regression is detected.

Follow-up CL on https://codereview.webrtc.org/2788883002/ where I add a new
test which has to be enabled manually (will not run by default on bots).
Measures loopback latency and reports the min, max and average values for
a full duplex audio session.
The latency is measured like so:
- Insert impulses periodically on the output side.
- Detect the impulses on the input side.
- Measure the time difference between the transmit time and receive time.
- Store time differences in a vector and calculate min, max and average.
This test needs the '--gtest_also_run_disabled_tests' flag to run and also
some sort of audio feedback loop. E.g. a headset where the mic is placed
close to the speaker to ensure highest possible echo. It is also recommended
to run the test at highest possible output volume.
How to run:
./out/Debug/modules_unittests --gtest_filter=AudioDeviceMeasureLoopbackLatency --gtest_also_run_disabled_tests
Example output (on Linux machine):
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from AudioDeviceTest
[ RUN ] AudioDeviceTest.DISABLED_MeasureLoopbackLatency

There's some code that resets the ICE role on an ICE restart (behavior
that's specified in ICE, but removed from ICEbis). And it wasn't taking
into account that the remote endpoint may be an ICE lite endpoint, in
which case the WebRTC endpoint's role should always be "controlling".

RTCVideoEncoder does not propagate RTP timestamps properly for encoded video frames, and as such whenever switching between simulcast layers there's a large timestamp gap that causes the incoming stream to freeze (timestamps look like they're either too far ahead or too far behind the previous frame).
Ideally RTCVideoEncoder would propagate these timestamps, but even so, when there's a large timestamp gap it would seem reasonable that the receiver resets quickly and consider this to be a new stream.
This CL detects the large jump for timestamps, if that happens, we reset the time extrapolator, which is the class for convertion from RTP timestamp to clock time.

This CL improves the echo cancellation performance on setups where
headsets are used (systems with such low echo path gain
that no correlation between the render and capture signals
can be found) in 4 ways:
1) The echo path gain for systems with headsets is assumed to be
nonzero.
2) The stationary component of the render power is not included
in nonlinear echo power estimate.
3) The behavior after echo path gain changes is made less cautious.
4) The detection of systems with headsets is made more rapid.

It's not possible to enable it for the rtc_base_approved

this CL doesn't attempt to fix that.
Changes made:
* Move webrtc/system_wrappers/include/stringize_macros.h into
webrtc/base:rtc_base_approved_unittests (and corresponding
unit test to rtc_base_approved_unittests).
* Move md5digest.* from rtc_base_approved to rtc_base_test_utils target.
* Move webrtc/system_wrappers/include/stringize_macros.h (+test) into
webrtc/base.
* Remove unused use include of webrtc/base/fileutils.h in
webrtc/base/pathutils.cc
