The H.264 does not contain picture IDs and are not sufficient to
determine that a packet may be skipped. This causes retransmission
requests for FEC that are currently dropped by the sender (since they
should be redundant).
The receiver is then unable to continue without having the packet gap
filled (unlike VP8/VP9 which moves on since it has a consecutive stream
of picture IDs).
Even if FEC retransmission did work it's a huge waste of bandwidth,
since it just adds additional overhead that has to be unconditionally
transmitted. This bandwidth is better used to send higher-quality
frames.

We'd like to completely replace rtc::scoped_ptr with std::unique_ptr.
This is a first trial CL to see if using unique_ptr causes any
problems.
(As a side effect of removing the scoped_ptr.h include in buffer.h,
I had to fix broken includes in no less than three files.)

This reverts "iOS: Add mb_type config for GYP builders."
and also removes Goma from these builders, as it will not work for WebRTC
since MB's GYP mode is hardcoded to use gyp_chromium.
MB should be working for GN since it's a stand-alone tool.
Goma doesn't work since $(goma_dir) in the JSON throws an error during
compile. So let's turn off Goma for these bots for now.

This makes sense since the buffered data is only used by
the echo subtraction method. Furthermore, it simplifies the
upcoming modifications to the echo subtraction method since
the way the buffering is done can then be specific for the
echo subtraction implementation used.
The change is bitexact and this was verified using a fairly
extensive bitexactness suite.

In some rare occations (very low energy signal), a shift value happened
to be negative. This is now fixed by using the WEBRTC_SPL_SHIFT_W32,
which in essence checks the sign of the number of shifts and performs a
right or left shift accordingly.
The fix reverts to how the code was written in old NetEq; see
4d363ae305/webrtc/modules/audio_coding/neteq/normal.c (165).

The previously disabled warnings that were inherited from
talk/build/common.gypi are now replaced by target-specific disabling
of only the failing warnings. Additional disabling was needed since the stricter
compilation warnings that applies to code in webrtc/.
License headers will be updated in a follow-up CL.
Other modifications:
* Updated the header guards.
* Sorted the includes using chromium/src/tools/sort-headers.py
except for these files:
talk/app/webrtc/peerconnectionendtoend_unittest.cc
talk/app/webrtc/java/jni/androidmediadecoder_jni.cc
talk/app/webrtc/java/jni/androidmediaencoder_jni.cc
webrtc/media/devices/win32devicemanager.cc
The HAVE_SCTP define was added for the peerconnection_unittests target
in api_tests.gyp.
I also checked that none of
SRTP_RELATIVE_PATH
HAVE_SRTP
HAVE_WEBRTC_VIDEO
HAVE_WEBRTC_VOICE
were used by the talk/app/webrtc code.

Previously shared memory buffers for DesktopCapturer were created
using DesktopCapturer::Callback::CreateSharedBuffer(). That made it
difficult to proxy DesktopCapturer interface from one thread to another.
This CL adds SharedBufferFactory interface that's allowed to be called
on a background thread. This also simplifies clients that don't
need to use shared memory, as they no longer need to override
CreateSharedBuffer().
