This patch series splits the algorithms in IPU3 into a modular form.
When the Metadata class was discussed a proposal from Kieran was to have
a fully-defined structure which would be used to pass the context
between algorithms and the IPAIPU3 class, as well as between the
algorithms themselves.
The algorithms are statically emplaced in a list for the moment, and a
registration system may be used later.
In order to demonstrate how to add a new algorithm, patch 3/5
demonstrates how the gamma table is calculated.
Patch 4/5 and 5/5 move the AWB and AGC algorithms currently used.
