Ensure that the ring buffer does not return a pointer into the buffer if
no data is available to read.
The ring buffer fix is not directly applicable to issue webrtc:7845, but may cause related memory errors.

Prior to https://codereview.webrtc.org/2750783004/ Reset() intentionally
did not zero out the buffer. After that change, callers calling Reset()
and then mutable_data() were performing a wasteful zeroing.
This change adds ResetWithoutMuting() to match the old behavior and
switches the sole non-test caller of Reset() to use ResetWithoutMuting()
instead.

Initial CL for this effort, with a working RTCVideoEncoder/Decoder for H264
(wrapping the VideoToolbox codec).
Some notes / things left to do:
- There are some hard-coded references to codec types that are supported by
webrtc::VideoCodec, cricket::VideoCodec, webrtc::CodecSpecificInfo etc
since we need to convert to/from these types in ObjCVideoEncoder/Decoder.
These types would need to be more codec agnostic to avoid this.
- Most interfaces are borrowed from the design document for injectable
codecs in Android. Some data in the corresponding C++ classes is discarded
when converting to the Obj-C version, since it has fewer fields. I have not
verified whether all data that we do keep is needed, or whether we might be
losing anything useful in these conversions.
- Implement the VideoToolbox codec code directly in the RTCVideoEncoderH264
classes, instead of wrapping webrtc::H264VideoToolboxEncoder / decoder.
Eliminates converting between ObjC/C++ types outside the ObjCVideoEncoder/
Decoder wrapper classes.
- List the injected codec factory's supported codecs in the list of codecs in
AppRTCMobile.

On Windows8/10, we prefer cropping desired window out from a whole screen
capture due to some reasons. The problem is Win10 has an invisible border
around the window. If we leave the border, it will expose background a bit.
This cl is about to always remove the border of desired window on Win8/10.
This will help a lot to capturing still windows during window sharing.
This cl still can't handle the background exposure issue when you move the
target window around during capturing. More investigation is needed.

Some frames are already marked as 'timing frames' via video-timing RTP header extension. Timestamps along full WebRTC pipeline are gathered for these frames. This CL implements reporting of these timestamps for a single
timing frame since the last GetStats(). The frame with the longest end-to-end delay between two consecutive GetStats calls is reported.
The purpose of this timing information is not to provide a realtime statistics but to provide debugging information as it will help identify problematic places in video pipeline for outliers (frames which took longest to process).

* Remove the ReleaseDecoder and Release methods that were used in combination with deleting the decoder object. Now simply deleting the object does the right thing.
* Remove 'friend' relationship between the two classes since they don't need to touch each other's state directly anymore.
* Use std::unique_ptr for holding pointers and transferring ownership.

The implementation of this method did not follow the description in
the method comment. It was supposed to delete all packets in a range
[A, B], but if at least one packet in the buffer had a timestamp lower
than A, then no packets at all were discarded. This is now fixed.
