Add the new format describing the Mali C55's Statistics and Parameters
to videodev2. These come from the v8 of the C55 kernel driver series
[1]. Once the kernel driver is merged we can replace these temporary
manual additions with updates to the scripts that merge in the
kernel headers.

The getFormat function takes the aspect ratio and the area of the
requested size into account when choosing the best sensor size. In case
the sensor is connected to an rkisp1 the maximum supported frame size of
the ISP is another constraining factor for the selection of the best
format. Add a maxSize parameter to support such a constraint.

The inputCropBounds_ member of the V4L2M2MConverter::Stream class is
only initialized after a V4L2M2MConverter::configure() call, when the
streams are initialized.
However, the converter has crop limits that do not depend on the
configured Streams, and which are currently not accessible from the
class interface.
Add a new inputCropBounds() function to the V4L2M2MConverter class
that allows to retrieve the converter crop limits before any stream
is configured.
This is particularly useful for pipelines to initialize controls and

Add the new Matrix class to the build.

Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The Matrix constructor that takes a std::vector is meant and only used
to initialize a Matrix from an initializer list. Using a std::vector is
problematic for two reasons. First, it requires constructing a vector,
copying the data from the initializer list, which is an expensive
operation. Then, the vector size can't be verified at compile time,
making the constructor unsafe.
The first issue could be solved by replacing the vector with a
std::initializer_list or a Span. The second issue would require checking
the initializer list size with a static assertion, or restricting usage
of the constructor to fixed-extent spans. Unfortunately, even if the
size of initializer lists is always known at compile time, the
std::initializer_list::size() function is a compile-time constant only
for constant initializer lists. Using a span would work better, but
construction of a fixed extent span from an initializer list must be
explicit, making the API cumbersome.
We can solve all those issues by passing an std::array to the
constructor. Construction of an array from an initializer list can be
implicit and doesn't involve a copy, and the array size is a template
parameter and therefore guaranteed to be a compile-time constant.

The terms "shutter" and "shutter speed" are used through libcamera to
mean "exposure time". This is confusing, both due to "speed" being used
as "time" while it should be the inverse (i.e. a maximum speed should
correspond to the minimum time), and due to "shutter speed" and
"exposure time" being used in different places with the same meaning.
To improve clarity of the code base and the documentation, use "exposure
time" consistently to replace "shutter speed".
This rename highlighted another vocabulary issue in libcamera. The
ExposureModeHelper::splitExposure() function used to document that it
splits "exposure time into shutter time and gain". It has been reworded
to "split exposure into exposure time and gain". That is not entirely
satisfactory, as "exposure" has a defined meaning in photography (see
https://en.wikipedia.org/wiki/Exposure_(photography)) that is not
expressed as a duration. This issue if left to be addressed separately.

std::from_chars(), introduced in C++17, is a fast, locale-independent
string-to-arithmetic conversion function. The C++ standard library
provides overloads for all integer types, making it a prime candidate to
replace the manual handling of integer sizes in the YamlParser string to
integer conversion.
Compared to std::strtol(), std::from_chars() doesn't recognize the '0x'
prefix or '+' prefix, and doesn't ignore leading white space. As the
YamlParser doesn't require those features, std::from_chars() can be used
safely, reducing the amount of code.
C++17 also requires the standard C++ library to provide overloads for
floating-point types, but libc++ does not implement those. The float and
bool implementations of YamlParser::Getter::get() are therefore kept
as-is.

Debug metadata often occurs in places where the metadata control list is
not available e.g. in queueRequest() or processStatsBuffer() or even in
a class far away from the metadata handling code. It is therefore
difficult to add debug metadata without adding lots of boilerplate
code. This can be mitigated by recording the metadata and forwarding it
to the metadata control list when it becomes available. To solve the
issue of code that is far away from the metadata context, add a chaining
mechanism to allow loose coupling at runtime.

The names used by the IPA interface and the names used for buffer
completions handlers in libcamera clash in the use of the term "buffer".
For example video device buffer completion handler is called
"bufferReady" and the IPA event to ask the IPA to compute parameters are
called "fillParamsBuffers". This makes it hard to recognize which
function handles video device completion signals and which ones handle
the IPA interface events.
Rationalize the naming scheme in the IPA interface function and events
and the signal handlers in the pipelines, according to the
following table. Remove the name "buffer" from the IPA interface events
and events handler and reserve it for the buffer completion handlers.
Rename the IPA interface events and function to use the 'params' and
'stats' names as well.
IPA Interface:
- fillParamsBuffer -> computeParams [FUNCTION]
- processStatsBuffer -> processStats [FUNCTION]
- paramFilled -> paramsComputed [EVENT]
Pipeline handler:
- bufferReady -> videoBufferReady [BUFFER HANDLER]
- paramReady -> paramBufferReady [BUFFER HANDLER]
- statReady -> statBufferReady [BUFFER HANDLER]
- paramFilled -> paramsComputed [IPA EVENT HANDLER]
Cosmetic change only, no functional changes intended.

In order to support a default implementation for camera sensors when no
better implementation matches, libcamera needs to try "specialized"
implementations first and pick the default last. Make this possible by
adding a priority value for factories. Newly registered factories are
inserted in the factories list sorted by descending priority, and the
default factory uses a negative priority to be inserted as the last
element.
This mechanism may be a bit overkill in the sense that there is no
expected use cases for priorities other than trying the default last,
but the implementation is simple and easy to understand.

Part of the code is likely worth keeping as common helpers in a base

In many cases a static string literal is used as key. Thus
having the argument type be `const std::string&` is suboptimal
since an `std::string` object needs to be constructed before
the call.
C++17 introduced `std::string_view`, using which the call
can be done with less overhead, as the `std::string_view`
is non-owning and may be passed in registers entirely.
So make `YamlObject::{contains,operator[]}` take the string keys
in `std::string_view`s.
Unfortunately, that is not sufficient yet, because `std::map::find()`
takes an reference to `const key_type`, which would be `const std::string&`
in the case of `YamlParser`. However, with a transparent comparator
such as `std::less<>` `std::map::find()` is able to accept any
object as the argument, and it forwards it to the comparator.
So make `YamlParser::dictionary_` use `std::less<>` as the comparator
to enable the use of `std::map::find()` with any type of argument.

This patch adds Algorithm::prepare call for the defined algorithms.
This is preparation only since there are currently no Algorithm based
algorithms defined.

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.

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.

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.

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.

Software ISP image processing algorithms are currently defined in a
simplified way, different from other libcamera pipelines. This is not
good for several reasons:
- It makes the software ISP code harder to understand due to its
different structuring.
- Adding more algorithms may make the code harder to understand
generally.
- Mass libcamera code changes may not be easily applicable to software
ISP.
- Algorithm sharing with other pipelines is not easily possible.
This patch introduces basic software ISP IPA skeletons structured
similarly to the other pipelines. The newly added files are currently
not used or compiled and the general skeleton structures don't contain
anything particular. It is just a preparation step for a larger
refactoring and the code will be actually used and extended as needed in
followup patches.
