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.

3e3b6f2805 Remove Chromium Clang warnings only on Windows.
A previous CL (https://codereview.webrtc.org/2281513002) broke Windows, Mac and Linux bots in WebRTC's Chromium FYI, by suppressing these warnings when they hadn't been set.

This CL fixes it suppressing warnings only on Windows.

Move the webrtc/test/test_support/metrics sources into
test_support[_unittests] targets.
This is essentially reverting https://webrtc-codereview.appspot.com/5789004
and moving these sources back to the right target.

Add missing foreman_cif.yuv resource needed for these tests.

For MIPS, a compile error was surfacing for logcat_trace_context.h when
flipping bot to GN, which was fixed.

a6219cc3ef FileWrapper[Impl] modifications and actually remove the "Impl" class.
This is a somewhat involved refactoring of this class. Here's an overview of the changes:

* FileWrapper can now be used as a regular class and instances allocated on the stack.
* The type now has support for move semantics and copy isn't allowed.
* New public ctor with FILE* that can be used instead of OpenFromFileHandle.
* New static Open() method.  The intent of this is to allow opening a file and getting back a FileWrapper instance.  Using this method instead of Create(), will allow us in the future to make the FILE* member pointer, to be const and simplify threading (get rid of the lock).
* Rename the Open() method to is_open() and make it inline.
* The FileWrapper interface is no longer a pure virtual interface.  There's only one implementation so there's no need to go through a vtable for everything.
* Functionality offered by the class, is now reduced.  No support for looping (not clear if that was actually useful to users of that flag), no need to implement the 'read_only_' functionality in the class, since file APIs implement that already, no support for *not* managing the file handle (this wasn't used).  OpenFromFileHandle always "manages" the file.
* Delete the unused WriteText() method and don't support opening files in text mode.  Text mode is only different on Windows and on Windows it translates \n to \r\n, which means that files such as log files, could have a slightly different format on Windows than other platforms.  Besides, tools on Windows can handle UNIX line endings.
* Remove FileName(), change Trace code to manage its own path.
* Rename id_ member variable to file_.
* Removed the open_ member variable since the same functionality can be gotten from just checking the file pointer.
* Don't call CloseFile inside of Write.  Write shouldn't be changing the state of the class beyond just attempting to write.
* Remove concept of looping from FileWrapper and never close inside of Read()
* Changed stream base classes to inherit from a common base class instead of both defining the Rewind method. Ultimately, Id' like to remove these interfaces and just have FileWrapper.
* Remove read_only param from OpenFromFileHandle
* Renamed size_in_bytes_ to position_, since it gets set to 0 when Rewind() is called (and the size actually does not change).
* Switch out rw lock for CriticalSection. The r/w lock was only used for reading when checking the open_ flag.

53cf3463c0 Fix race condition in EventTimerPosix
The intended signalling from StartTimer() to Process() is that
created_at_.tv_sec is set to 0, and timer_event_->Set() is then called
in order to wake the process thread from timer_event_->Wait(). When this
happens the process thread will return early and the run Process()
again. This time it will pick up created_at_.tv_sec = 0 and run a new
Wait() call with the desired end time.

However if the process thread was NOT blocking on timer_event_->Wait()
when timer_event_->Set() was called from StartTimer() it will mean that
the first call to timer_event_->Wait() from Process(), AFTER the new
time has been configured (count_ = 1), will return early.

If the timer is not periodic it means that Set() will never be called,
and any calls will Wait() will block until the time out.

The solution is to always reset the event in timer_event_ on the first
call to timerEvent_->Wait(), after a timer has started.

Also some general cleanup.

"WebRTC.Video.AVSyncOffsetInMs"

The absolute value of the sync offset between a rendered video frame and the latest played audio frame is measured per video frame. The average offset per received video stream is recorded when a stream is removed.

Updated sync tests in call_perf_tests.cc to use this implementation.

c2148a50d2 Integrate helper macros for calling histograms with different names (real-time vs screenshare and rampup metrics).
Sparse macro is replaced and new implementation in metrics.h is used.

040b79ff7e Add helper macros for calling a histogram with different names.
To be used when a metric is used in different modes such as real-time vs screenshare (will be done in https://codereview.webrtc.org/1564923008/).

1c3909899d Use rtc::time for all your timing needs!
Initial step of unifying so that base/timeutils.h and Clock/TimeTime
from system_wrappers use the same implementation.

e791ffd638 Remove non-monotonic clock support
Real time clock may cause problems as they can move (even backwards) if
the clock is changed, eg updated by NTP.

Non-monotonic clocks still in use on some platform (I'm looking at you,
Apple) for timed waits, but that should be less of an issue than actual
timestamps.

rtc::CriticalSection is now lockable from const methods and no longer
need to remain mutable.
