Move aom source to a sub-directory under media/libaom

There is no damned reason to treat this differently than any other media lib given its license and there never was.

-// Scalable Encoder
-// ==============
-//
-// This is an example of a scalable encoder loop. It takes two input files in
-// YV12 format, passes it through the encoder, and writes the compressed
-// frames to disk in OBU format.
-//
-// Getting The Default Configuration
-// ---------------------------------
-// Encoders have the notion of "usage profiles." For example, an encoder
-// may want to publish default configurations for both a video
-// conferencing application and a best quality offline encoder. These
-// obviously have very different default settings. Consult the
-// documentation for your codec to see if it provides any default
-// configurations. All codecs provide a default configuration, number 0,
-// which is valid for material in the vacinity of QCIF/QVGA.
-//
-// Updating The Configuration
-// ---------------------------------
-// Almost all applications will want to update the default configuration
-// with settings specific to their usage. Here we set the width and height
-// of the video file to that specified on the command line. We also scale
-// the default bitrate based on the ratio between the default resolution
-// and the resolution specified on the command line.
-//
-// Encoding A Frame
-// ----------------
-// The frame is read as a continuous block (size = width * height * 3 / 2)
-// from the input file. If a frame was read (the input file has not hit
-// EOF) then the frame is passed to the encoder. Otherwise, a NULL
-// is passed, indicating the End-Of-Stream condition to the encoder. The
-// `frame_cnt` is reused as the presentation time stamp (PTS) and each
-// frame is shown for one frame-time in duration. The flags parameter is
-// unused in this example.
-
-// Forced Keyframes
-// ----------------
-// Keyframes can be forced by setting the AOM_EFLAG_FORCE_KF bit of the
-// flags passed to `aom_codec_control()`. In this example, we force a
-// keyframe every <keyframe-interval> frames. Note, the output stream can
-// contain additional keyframes beyond those that have been forced using the
-// AOM_EFLAG_FORCE_KF flag because of automatic keyframe placement by the
-// encoder.
-//
-// Processing The Encoded Data
-// ---------------------------
-// Each packet of type `AOM_CODEC_CX_FRAME_PKT` contains the encoded data
-// for this frame. We write a IVF frame header, followed by the raw data.
-//
-// Cleanup
-// -------
-// The `aom_codec_destroy` call frees any memory allocated by the codec.
-//
-// Error Handling
-// --------------
-// This example does not special case any error return codes. If there was
-// an error, a descriptive message is printed and the program exits. With
-// few exeptions, aom_codec functions return an enumerated error status,
-// with the value `0` indicating success.
