705ecc5dda GN: Change group deps to public_deps.
During GN vs GYP auditing it was discovered that some
GN targets that had public_configs were not exposing them
to dependents where the dependent depended on a group, which
in turn included that target as a dependency. Instead of
changing those public_configs to all_dependent_configs
(which would be a change from GYP), it's better to just change
those group targets to use public_deps instead.

TESTED=Generated GYP and GN project files on Mac and ran the
tools/gyp_flag_compare.py script before and after this patch was
applied. The file in question used for inspection was the
webrtc/api/webrtcsessiondescriptionfactory.cc
which is a part of the libjingle_peerconnection target.

fdafab84bc Fix issues with rtc_stats_unittests tests so that they can run on bots.
This target is not run on bots so a couple of issues went under the
radar. If we expose the tests and run them on the bots[1] two issues are
surfaced which this CL fixes. After this CL lands we can enable this
target on the bots without it going red.

rtcstats_unittest.cc: Fix const char* string comparison issue by
comparing with strcmp instead of equality check.

rtcstatscollector_unittest.cc: Fix TSAN issue by constructing
ScopedFakeClock before spawning Threads.

c82f2e1613 RTCStatsCollector collecting stats on multiple threads.
Changes GetStatsReport to a callback-based function. Stats collection
is dispatched to three different stats collecting methods, being
invoked asynchronously on the signaling, worker and network threads.
The three resulting stats reports are merged into one before returned.

The only current stats being collected is on the signaling thread, but
a FakeRTCStatsCollector is able to test the multi-threaded and
stats-merging behaviors. Future CLs simply have to put their stats
collecting code in the appropriate ProducePartialResultsOnFooThread
method.

38a2132b02 GN: Introduce templates.
Defines the rtc_executable, rtc_source_set, rtc_test and
rtc_static_library templates.

These templates provide no functionality yet, but will enable common
configuration to be introduced, avoiding repetition in every target

Changes summary:
- Prepend rtc_ to test, source_set, executable and static_library targets
- Change "configs -= [" to "suppressed_configs += ["
- Include webrtc/build/webrtc.gni where it wasn't included yet
- Delete import("//testing/test.gni"), since rtc_test makes it unnecessary.

0e6758d7ef RTCStatsCollector: timestamps updated.
Using a timestamp based on a timer that is monotonically increasing for
the cache, so that cache's freshness can be checked regardless of if
system clock is modified.

Using a system clock for the stats' timestamp, which needs to be
relative to UNIX epoch (Jan 1, 1970, UTC).

This CL removes the dependency on faketiming.h.

d565b73121 RTCStatsCollector and RTCPeerConnectionStats added.
This is the stats collector for the new stats types, RTCStats[1] and
RTCStatsReport[2]. It so far only produces RTCPeerConnectionStats[3] as
an example of how it would collect stats. Each RTCStats subclass will
get a corresponding RTCStatsCollector::ProduceFooStats().

Stats reports are cached and returned as const references (ref
counting). This allows stats to be inspected by multiple observers and
across multiple threads. No copies will have to be made when surfacing
this to Blink or other places.

The current implementation of ProducePeerConnectionStats() only look at
existing DataChannels. This might be incorret if data channels can be
removed? Will investigate in a follow-up, crbug.com/636818.

6d183ac27a RTCStatsReport: Take ownership of other's stats with TakeMembersFrom
This would make it possible to gather stats on multiple threads, store
the results in multiple reports and to merge the results.

Added rtcstatsreport_unittest.cc, moving a RTCStatsReport-related test
from rtcstats_unittest.cc. Added more unittests covering the order of
stats and TakeMembersFrom.

Also changed RTCStatsReport[] to RTCStatsReport::Get to avoid
confusion with other usages of the [] operator.

615d3013de RTCStats and RTCStatsReport added (webrtc/stats).
The old and new getStats are very different. This CL proposes rewriting
the new getStats from scratch with a bottom-up approach, starting with
the fundamental stats classes. This will allow cleaner and more
efficient code that is more aligned with the spec.

RTCStats and subclasses are the equivalent to RTCStats and RTCStats-
-derived dictionaries from the specs[1][2]. The dictionary members are
public member variables of type RTCStatsMember<T>, where T is one of the
supported types. All members derive from RTCStatsMemberInterface and
iteration of members is possible with RTCStats::Members().
The members are not stored in a map for performance and readability.
Type checking is supported with static class variables, kType.

Only the supported member types T are specialized and may be
instantiated, and sequences are supported with std::vector<...>. Type
checking is again supported with static class variables, kType.

RTCStatsReport is the equivalent from the spec[3], and maps RTCStats::id
to RTCStats-objects. RTCStatsReport is reference counted. It and its
contained stats may be destroyed on any thread. When the
RTCStatsCollector is added in a follow-up CL, it will return const
references to the RTCStatsReports. This means copies don't have to be
made for multiple stats observers or when jumping threads. In fact, no
copies of any stats will have to be made in surfacing stats to Blink.

This adds the new folder webrtc/stats/, with target rtc_stats and binary
rtc_stats_unittests. Public api headers are placed in webrtc/api/ and
.cc files are placed in webrtc/stats/.
