-Make raw bayer header size change from 20 to 16 affect rev072a only, my 2
rev012a cams both have a header size of 20
-While testing this I also tested the new exposure setting (good work on
finding the register JF), and after quite a bit of testing have found out the
exact meaning of the register, this patch modifies setexposure to control
the exposure over a much wider range.

The crash is due to USB exchanges done at interrupt level.
These exchanges, tied to autogain, are now done by the application.
Also, there is a fix about autogain start.
