Note, this changes the behavior of visorchannel_read(). The old code would return the channel header, if the offset argument was 0, and the caller tried to read beyond the size of the visorchannel. Note this only worked for offset == 0, but not for (offset > 0) && (offset < header_size), which was inconsistent. The new implementation returns an error if someone tries to read beyond the visorchannel size. Signed-off-by:
