fc22e03eb8 Add AVFoundation video capture support to Mac objc SDK (based on iOS)
The AppRTCDemo app on Mac OSX does not show or send local video streams,
as ACFoundation capture session is not compiled in or implemented in
the appropriate places.  This is the first part of a two-part patch
that implements local capture on the Mac for AppRTCDemo

P.S. This is my first patch to WebRTC.   I didn't see any relevant tests, but I could write some if you can point me at a location. Also, I don't have access to the automated tests (I don't think)

f2a1c89241 Add r-value constructor for RefCountedObject.
Previously RefCountedObject was passing all parameters by value.
This meant that it was hard to use it with movable types, such
as unique_ptr<>. Now there is a constructor that takes r-value,
which means that RefCountedObject<std::unique_ptr<foo>> can be
initialized by passing std::unique_ptr<foo> to the constructor.

73fbcf9237 Don't re-determine ICE role on an ICE restart.
This only causes an increased likelihood of role conflicts as each peer
is picking a new role. It also means that if ICE is restarted for only
one media stream, roles can be different across media streams (which isn't
even allowed).

For more explanation of why this is unnecessary and should be changed,
see this discussion:

a10740239d Fix UBSan errors (signed integer overflow)
WebRtcSpl_CrossCorrelation and WebRtcSpl_DotProductWithScale compute
the int32 sum of pairwise products from two int16 arrays. So as to
avoid overflow (which could otherwise happen when as little as two
products were summed), the products are right-shifted by an amount
specified by the caller.

This CL changes WebRtcIlbcfix_MyCorr and WebRtcIlbcfix_Smooth to give
sufficient right-shift amounts, instead of ones that may be too small
and cause overflow.

3bcedd3595 GN: Add SDK tests to rtc_unittests.
In https://codereview.webrtc.org/2034923003 it was discovered
that a test binary rtc_sdk_peerconnection_objc_tests was
a dependency to rtc_unittests. Unfortunately gtest doesn't
include dependent executables into the same test executable;
only libraries (so theses tests weren't run).

This CL incorporates those tests into rtc_unittests and
does the same changes to the GN build.

6b4b5f3770 Add sender controlled playout delay limits
This CL adds support for an extension on RTP frames to allow the sender
to specify the minimum and maximum playout delay limits.

The receiver makes a best-effort attempt to keep the capture-to-render delay
within this range. This allows different types of application to specify
different end-to-end delay goals. For example gaming can support rendering
of frames as soon as received on receiver to minimize delay. A movie playback
application can specify a minimum playout delay to allow fixed buffering
in presence of network jitter.

There are no tests at this time and most of testing is done with chromium
webrtc prototype.

On chromoting performance tests, this extension helps bring down end-to-end
delay by about 150 ms on small frames.

a601f5c863 Separating internal and external methods of RtpSender/RtpReceiver.
This moves the implementation specific methods to separate classes
(RtpSenderInternal/RtpReceiverInternal) so that the interface classes
represent the interface that external applications can rely on.

The reason this wasn't done earlier was that PeerConnection needed
to store proxy pointers, but also needed to access implementation-
specific methods on the underlying objects. This is now possible
by using "RtpSenderProxyWithInternal<RtpSenderInternal>", which is a proxy
that implements RtpSenderInterface but also provides direct access
to an RtpSenderInternal.

f5f03e823c Reland of: Improving the fake clock and using it to fix a flaky STUN timeout test.
When the fake clock's time is advanced, it now ensures all pending
queued messages have been dispatched. This allows us to write a
"SIMULATED_WAIT" macro that ticks the simulated clock by milliseconds up
until the target time.

Useful in this case, where we know the STUN timeout should take a total
of 9500ms, but it would be overly complex to write test code that waits
for each individual timeout, ensures a STUN packet has been
retransmited, etc.

(The test described above *should* be written, but it belongs in
p2ptransportchannel_unittest.cc, not webrtcsession_unittest.cc).

Apparently a thread is still alive even after destroying WebRTCSession. Need to think of a way to fix this, without adding a critical section around g_clock (since that would hurt performance).

3ee5614650 GN: Add rtc_unittests
Everything except the dependency on
sdk/sdk_tests.gyp:rtc_sdk_peerconnection_objc_tests is included.
That one actually doesn't make those tests run as part of rtc_unittests
(by design). Fixing that + add them will done in aseparate CL.

BUG=webrtc:5949
TESTED=Built and ran rtc_unittests on Mac.
Verified the number of tests matched a run on the bot (1213 tests executed).

4a627a8c13 Use std::unique_ptr<> to pass frame ownership in DesktopCapturer impls.
Previously raw pointers were used for owned DesktopFrame instances.
Updated all screen and window capturer implementations to use
std::unique_ptr<>.

Also includes some other cleanups in the capturers:
 - s/NULL/nullptr
 - moved default initializers to class definition.

Per
47183ba60b Handle Android stop capturer race.
With the current order of stop capture processing on Android,
OnMemoryBufferFrame and OnTextureFrame may be called halfway through
Stop(). They must therefore check for the case of a null capturer_.

There used to be such checks, but they were accidantally removed in
commit #12895, cl https://codereview.webrtc.org/1973873003.
