Setting the standard deviation to 0 is valid and should be interpreted
as directly using the sample value at the coordinates without weighting.
This is made explicit in the documentation for the Corruption Detection
extension:
http://www.webrtc.org/experiments/rtp-hdrext/corruption-detection
Also, change stddev to std_dev in halton_frame_sampler files.

For key frames: increase the sequence index until the last 7 bits are
all zeroes. If this results in an overflow, wraparound to 0.
Also:
* Allow setting and getting the sequence index
* Allow getting LayerId

This is to make it clear that this field indicate whether the upper bits
of the sequence number should be communicated. However, the current
implementation only sets the field if it is a key frame.

The functions will be used to map a frame's QP to its optimal standard
deviation for the Gaussian kernel for the filter applied in the
automatic corruption detection algorithm.
