3930b94021 libcamera: software_isp: Add contrast control
This patch introduces support for applying runtime controls to software
ISP.  It enables the contrast control as the first control that can be
used.

04d171e6b2 libcamera: software_isp: Call Algorithm::queueRequest
This patch adds Algorithm::queueRequest call for the defined algorithms.
As there are currently no control knobs in software ISP nor the
corresponding queueRequest call chain, the patch also introduces the
queueRequest methods and calls from the pipeline to the IPA.

This is preparation only since there are currently no Algorithm based
algorithms defined and no current software ISP algorithms support
control knobs.

ecbc05c4c5 libcamera: software_isp: Call Algorithm::configure
This patch adds Algorithm::configure call for the defined algorithms.
This is preparation only since there are currently no Algorithm based
algorithms defined.

A part of this change is passing IPAConfigInfo instead of ControlInfoMap
to configure() calls as this is what Algorithm::configure expects.

f06c344bd5 libcamera: software_isp: Track and pass frame ids
A previous preparation patch implemented passing frame ids to stats
processing but without actual meaningful frame id value passed there.
This patch extends that by actually providing the frame id and passing
it through to the stats processor.

The frame id is taken from the request sequence number, the same as in
hardware pipelines.

c64f2f197a libcamera: software_isp: Make stats frame and buffer aware
This patch adds frame and bufferId arguments to stats related calls.
Although the parameters are currently unused, because frame ids are not
tracked and used and the stats buffer is passed around directly rather
than being referred by its id, they bring the internal APIs closer to
their counterparts in hardware pipelines.

It serves as a preparation for followup patches that will introduce:

- Frame number tracking in order to switch to DelayedControls
  (software ISP TODO #11 + #12).
- A ring buffer for stats in order to improve passing the stats
  (software ISP TODO #2).

Frame and buffer ids are unrelated for the given purposes but since they
are passed together at the same places, the change is implemented as a
single patch rather than two, basically the same, patches.

cc3a3c46a5 libcamera: converter: Replace usage of stream index by Stream pointer
The converter interface uses the unsigned int output stream index to map
to the output frame buffers. This is cumbersome to implement new
converters because one has to keep around additional book keeping
to track the streams with their correct indexes.

The v4l2_converter_m2m and simple pipeline handler are adapted to
use the new interface. This work roped in software ISP as well,
which also seems to use indexes (although it doesn't implement converter
interface) because of a common conversionQueue_ queue used for
converter_ and swIsp_.

The logPrefix is no longer able to generate an index from a stream, and
is updated to be more expressive by reporting the stream configuration
instead, for example, reporting "1920x1080-MJPEG" in place of
"stream0".

447da4a11f libcamera: Rename DmaHeap class to DmaBufAllocator
Users of the DmaHeap class really just want some way to allocate
dma-buffers from userspace. This can also be done by using /dev/udmabuf
instead of using /dev/dma_heap/*.

Rename DmaHeap class to DmaBufAllocator in preparation of adding
/dev/udmabuf support.

And update the DmaHeap class docs to match including replacing references
to "dma-heap type" with "dma-buf provider".

This is a pure automated rename on the code ('s/DmaHeap/DmaBufAllocator/')
+ file renames + doc updates. There are no functional changes.

The DmaBufAllocator objects in vc4.cpp and software_isp.cpp are left named
dmaHeap_ to keep the changes to those 2 files to a minimum.

626172a16b libcamera: Drop file name from header comment blocks
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.
