The simple pipeline handler uses frame start events to apply sensor
controls through the DelayedControls class. The setSensorControls()
function applies the controls directly, which would result in controls
being applied twice, if it wasn't for the fact that the pipeline handler
forgot to enable the frame start events in the first place. Those two
issues cancel each other, but cause controls to always be applied
directly.
Fix the issue by only applying controls directly in setSensorControls()
if no frame start event emitter is available, and by enabling the frame
start events in startDevice() otherwise. Disable them in stopDevice()
for symmetry.

Furthermore, since `values.back()` is used, only the last element of

This patch applies color correction matrix (CCM) in debayering if the
CCM is specified. Not using CCM must still be supported for performance
reasons.
The CCM is applied as follows:
[r1 g1 b1] [r]
[r2 g2 b2] * [g]
[r3 g3 b3] [b]
The CCM matrix (the left side of the multiplication) is constant during
single frame processing, while the input pixel (the right side) changes.
Because each of the color channels is only 8-bit in software ISP, we can
make 9 lookup tables with 256 input values for multiplications of each
of the r_i, g_i, b_i values. This way we don't have to multiply each
pixel, we can use table lookups and additions instead. Gamma (which is
non-linear and thus cannot be a part of the 9 lookup tables values) is
applied on the final values rounded to integers using another lookup
table.
Because the changing part is the pixel value with three color elements,
only three dynamic table lookups are needed. We use three lookup tables
to represent the multiplied matrix values, each of the tables
corresponding to the given matrix column and pixel color.
We use int16_t to store the precomputed multiplications. This seems to
be noticeably (>10%) faster than `float' for the price of slightly less
accuracy and it covers the range of values that sane CCMs produce. The
selection and structure of data is performance critical, for example
using bytes would add significant (>10%) speedup but would be too short
to cover the value range.
The color lookup tables can be represented either as unions,
accommodating tables for both the CCM and non-CCM cases, or as separate
tables for each of the cases, leaving the tables for the other case
unused. The latter is selected as a matter of preference.
The tables are copied (as before), which is not elegant but also not a
big problem. There are patches posted that use shared buffers for
parameters passing in software ISP (see software ISP TODO #5) and they
can be adjusted for the new parameter format.
Color gains from white balance are supposed not to be a part of the
specified CCM. They are applied on it using matrix multiplication,
which is simple and in correspondence with future additions in the form
of matrix multiplication, like saturation adjustment.
With this patch, the reported per-frame slowdown when applying CCM is
about 45% on Debix Model A and about 75% on TI AM69 SK.
Using std::clamp in debayering adds some performance penalty (a few
percent). The clamping is necessary to eliminate out of range values
possibly produced by the CCM. If it could be avoided by adjusting the
precomputed tables some way then performance could be improved a bit.

Applying color correction matrix (CCM) in software ISP is optional due
to performance reasons. CCM is applied if and only if `Ccm' algorithm
is present in the tuning file.
Software ISP debayering is a performance critical piece of code and we
do not want to use dynamic conditionals there. Therefore we pass
information about CCM application to debayering configuration and let it
select the right versions of debayering functions using templates. This
is a trick similar to the previously used one for adding or not adding
an alpha channel to the output.
Debayering gets this information but it ignores it in this patch.
Actual processing with CCM is added in the followup patch.

Extend the `Camera::Private` constructor to initialize the control id map
of both properly.
Multiple pipeline handlers copy the sensor's property list and
set that as camera properties, and since the `CameraSensor{Legacy,Raw}`
classes set the proper id map, the camera properties will have it too.
However, some pipelines, e.g. `uvcvideo` or `virtual`, do not do so,
and thus there will be no id map set. To fix this, extend the
`Camera::Private` constructor to set `properties::properties`.
As for `controlInfo_`, all pipeline handlers overwrite it during
camera initialization (and thus it will have the correct id map),
but still initialize the id map so that it is set at all times.
