As the camera sensor helper now has the ability to provide the black
level, use it. Black levels can still be overwritten by the tuning
file, but the direction is to remove them from the tuning files and move
them into the sensor helpers.
Additionally interpret all values based on 16bits. The conversion to the
scale required by the hardware is done in process(). It ensures all the
values inside libcamera are the same scale and is in preparation for the
i.MX8MP where black levels are based on a 20bit scale. Note that this
breaks existing tuning files. The tuning files distributed with
libcamera will be fixed in a later patch.

Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.
The change was generated with the following script:
----------------------------------------
dirs="include/libcamera src test utils"
declare -rA patterns=(
['c']=' \* '
['cpp']=' \* '
['h']=' \* '
['py']='# '
['sh']='# '
)
for ext in ${!patterns[@]} ; do
files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done
done
----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

Now that the Algorithm::prepare() function takes a frame number, we can
use it to replace the IPAActiveState::frameCount member.

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.

In order to have the proper pixel levels, apply a fixed black level
correction, based on the imx219 tuning file in RPi. The value is 4096 on
16 bits, and the pipeline for RkISP1 is on 12 bits, scale it.
