cc6817e9ce Move current bitstream parser to more appropriate directory.
This CL groups together the code that has to do with parsing H264 bitstreams.
This code logically belongs together, and having it in the same directory not
only simplifies things from a project structure perspective, but also makes it
easier to refactor out common parts incrementally.
An added benefit is that this simplifies modular compilation, where for example
one would like a build of WebRTC without the H264 codec-specific parts.

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.

52033d6ea1 Add H264 bitstream rewriting to limit frame reordering marker in header
The VUI part an SPS may specify max_num_reorder_frames and
max_dec_frame_buffering. These may cause a decoder to buffer a number
of frame prior allowing decode, leading to delays, even if no frames
using such references (ie B-frames) are sent.

Because of this we update any SPS block emitted by the encoder.

Also, a bunch of refactoring of H264-related code to reduce code
duplication.

2c8a2964fd Tune QP-based quality thresholds.
Increases measure time for downscale back to 5 seconds, this is required
to not over-react on hand-waving or quick device rotations.

Also increase max thresholds for QP a bit to not overreact when quality
still looks somewhat OK. Min thresholds for H264 seemed very low and are
increased to be sure that we can go back up again. The window is still
quite big with the increased max QP.

Also changes libvpx thresholds to use the same thresholds as the
encoder, they were excessively low before and wouldn't adapt on bad QPs
at all before (but rely on >60% framedropping based on bitrates to go
down).

00b62b0849 Remove QualityScaler kDefaultLowQpDenominator.
This denominator doesn't make any semantic sense, it's better to use
real thresholds for when things look "good" or "bad" rather than
fractions of a max QP.

Applies to all platforms, not only Android now, 160x90 video looks
awful and there's no real point to going below QVGA.

Regressed behavior is actually desirable (go down to 360p instead of producing super-bad 720p).

7620be8492 Frame dropper improvements & cleanup
1. Fix the case of key frame accumulation being incorrect due to the chunk
    size being computed at the time of leak based on input frame rate. The issue
    is that the count is computed based on key frame ratio and the actual chunk
    size computed from current input frame rate. These can be wildly different
    especially at the beginning of the stream (key frame ratio defaults based
    on 30 fps) resulting in incorrect key frame accumulation causing large frame
    drops when the input frame rate is low.

    2. Add large delta frame compensation. The current code accounts for key frames
    but not large delta frames. This is a common occurence in some application
    (remote desktop as an example)

    3. Fixes an issue identified by the unit tests. The accumulation of
    key frames had an issue in the scenario of a high key frame ratio where
    the full key frame was not being accounted for.

    3. Removes fast mode and other methods that are mostly dead code.

    4. Cleans up variable names as per chromium style.

2557b86e76 modules/video_coding refactorings
The main purpose was the interface-> include rename, but other files
were also moved, eliminating the "main" dir.

To avoid breaking downstream, the "interface" directories were copied
into a new "video_coding/include" dir. The old headers got pragma
warnings added about deprecation (a very short deprecation since I plan
to remove them as soon downstream is updated).

Other files also moved:
video_coding/main/source -> video_coding
video_coding/main/test -> video_coding/test
