Add fields for minimum and maximum line length duration to the
CameraMode structure. This replaces the existing lineLength field.
Any use of the existing lineLength field is replaced by the new
minLineLength field, as logically we always want to use the fastest
sensor readout by default.
As a drive-by cosmetic change, split all fields in the CameraMode
structure into separate lines.

The existing tuning file format (version 1.0) requires the controller algorithms
to run in the same order as listed in the JSON structure. The JSON specification
does not mandate any such ordering, but the Boost JSON parser would maintain
this order.
In order to remove this reliance on the parser to provide ordering, introduce a
new version 2.0 format for the camera tuning file. In this version, the
algorithms are specified in a top level list node ("algorithms"), which does
require strict ordering of the elements.
A "version" node is added to distinguish between the version 1.0 and 2.0
formats. The absence of the "version" node implies version 1.0.
A "target" node is also added to specify the target platform for this
configuration.
Update the controller to support either version of the tuning file by looking
at the version node. CreateAlgorithm member function to now load and configure
each algorithm. Additionally, make CreateAlgorithm a private member, it does not
get called externally.
If a version 1.0 format tuning file is used, throw a warning message indicating
it will be soon deprecated.

When encountering errors, the Algorithm::read() function either uses
LOG(Fatal) or throws exceptions from the boost property_tree functions.
To prepare for replacing boost JSON parse with the YamlParser class,
give the Algorithm::read() function the ability to return an error code,
and propagate it all the way to the IPA module init() function.
All algorithm classes return a hardcoded 0 value for now, subsequent
commits will change that.

Under the right circumstances, the alsc calculations could spread the colour
errors across the entire image as lambda remains unbound. This would cause the
corrected image chroma values to slowly drift to incorrect values.
This change adds a config parameter (alsc.lambda_bound) that provides an upper
and lower bound to the lambda value at every stage of the calculation. With this
change, we now adjust the lambda values so that the average across the entire
grid is 1 instead of normalising to the minimum value.

We now handle disabling ("pausing") AWB in the same way as
AEC/AGC. Instead of letting the pause flag be set so that the code
never runs at all, we instead fix the manual settings to the current
values (but continue to be called).
The algorithm does not restart any calculations in this state, but
continues to add AWB metadata to every frame. Therefore certain other
algorithms that want to know it (CCM and ALSC, for example) can still
find it.

Applying the manual_r_ and manual_b_ values is entirely removed from
the asynchronous thread where their use constituted a race hazard. The
main thread now deals with them entirely, involving the following
changes.
1. SetManualGains() applies the new values directly to the
"sync_results", meaning that Prepare() will jump to the new values
immediately (which is a better behaviour).
2. Process() does not restart the asynchronous thread when manual
gains are in force.
3. The asynchronous thread might be running when manual gains are set,
so we ignore the results produced in this case.
