Extend the debug message in Awb::process() to log the means and color
temperature in addition to the gains. This is useful for debugging the
algorithm behaviour. While at it, set the showpoint flag to print a
fixed number of digits after the decimal point, making logs more
readable.

RkISP actually supports two modes for color means, RGB and YCbCr. The
variables where the means are stored are identically named regardless of
the color means mode that's been selected.
Since the gains are computed in RGB mode, a conversion needs to be done
when the mode is YCbCr, which is unnecessary when RGB mode is selected.
This adds support for RGB means mode too, by checking at runtime which
mode is selected at a given time. The default is still set to YCbCr mode
for now.

The AWB statistics are computed after the ISP applies the colour gains.
This means that the red, green and blue means do not match the data
coming directly from the sensor, but are multiplied by the colour gains
that were used for the frame on which the statistics have been computed.
The AWB algorithm needs to take this into account when calculating the
colour gains for the next frame. Do so by dividing the means by the
gains that were applied to the frame, retrieved from the frame context.

Rework the algorithm's usage of the active state and frame context to
store data in the right place.
The active state stores two distinct categories of information:
- The consolidated value of all algorithm controls. Requests passed to
the queueRequest() function store values for controls that the
application wants to modify for that particular frame, and the
queueRequest() function updates the active state with those values.
The active state thus contains a consolidated view of the value of all
controls handled by the algorithm.
- The value of parameters computed by the algorithm when running in auto
mode. Algorithms running in auto mode compute new parameters every
time statistics buffers are received (either synchronously, or
possibly in a background thread). The latest computed value of those
parameters is stored in the active state in the process() function.
The frame context also stores two categories of information:
- The value of the controls to be applied to the frame. These values are
typically set in the queueRequest() function, from the consolidated
control values stored in the active state. The frame context thus
stores values for all controls related to the algorithm, not limited
to the controls specified in the corresponding request, but
consolidated from all requests that have been queued so far.
For controls that can be specified manually or computed by the
algorithm depending on the operation mode (such as the colour gains),
the control value will be stored in the frame context in
queueRequest() only when operating in manual mode. When operating in
auto mode, the values are computed by the algorithm and stored in the
frame context in prepare(), just before being stored in the ISP
parameters buffer.
The queueRequest() function can also store ancillary data in the frame
context, such as flags to indicate if (and what) control values have
changed compared to the previous request.
- Status information computed by the algorithm for a frame. For
instance, the colour temperature estimated by the algorithm from ISP
statistics calculated on a frame is stored in the frame context for
that frame in the process() function.
The active state and frame context thus both contain identical members
for most control values, but store values that have a different meaning.

The RkISP1 IPA module creates a single instance of its IPAFrameContext
structure, effectively using it more as an active state than a per-frame
context. To prepare for the introduction of a real per-frame context,
move all the members of the IPAFrameContext structure to a new
IPAActiveState structure. The IPAFrameContext becomes effectively
unused at runtime, and will be populated back with per-frame data after
converting the RkISP1 IPA module to using a frame context queue.
The IPAActiveState structure will slowly morph into a different entity
as individual algorithm get later ported to the frame context API.
While at it, fix a typo in the documentation of the
Agc::computeExposure() function that incorrectly refers to the frame
context instead of the global context.

libipa defines an abstract Algorithm class template that is specialized
by IPA modules. IPA modules then instantiate and manage algorithms
internally, without help from libipa. With ongoing work on tuning data
support for the RkISP1, and future similar work for the IPU3, more code
duplication for algorithms management is expected.
To address this and share code between multiple IPA modules, introduce a
new Module class template that will define and manage top-level concepts
for the IPA module.
The Module class template needs to be specialized with the same types as
the Algorithm class. To avoid manual specialization of both classes,
store the types in the Module class, and replace the template arguments
of the Algorithm class with a single Module argument from which the
other types are retrieved.
