Double the bitrate to see if we can reduce the blockiness.

Working on depth data processing.
Merge branch 'master' of https://github.com/worklist/hifi into pointy
Use only valid values to compute mean, and use the post-warp data to avoid
breaking on head tilt (because we were using the bounds of the rotated rect,
which included too much background).
Ignore maximum values when computing the depth.
When we have a mean face depth, use that rather than the face size to
estimate the z coordinate.
Use the V channel to provide masking information, indicating invalid depths.
Send color and depth as separate streams (rather than one on top of the other)
so that we can control their bitrates separately.
Removed the magic from a number.
Masking tweak.
Merge pull request #731 from ey6es/pointy

Various tweaks to depth streaming: send depth in separate stream from video (rather than one on top of the other); better computation of mean face depth; use mean face depth to calculate forward/backward lean; send valid mask in V channel.
