Add support to ControlId for querying direction information. This allows
applications to query whether a ControlId is meant for being set in
controls or to be returned in metadata or both. This also has a side
effect of properly encoding this information, as previously it was only
mentioned losely and inconsistently in the control id definition.

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.

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.

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.

Python scripts run as part of the build process need to take a few
actions specific to the environment in which they operate. One of those
is disabling the Python bytecode cache, to avoid writing .pyc files to
the source tree. This is done manually in the IPC generate.py and
parser.py scripts.
The current implementation is not ideal because it hardcodes in the
scripts information related to the environment in which they operate. As
those scripts are part of libcamera this is more of a theoretical issue
than a practical one. A second issue is that future Python scripts will
need to duplicate similar mechanisms, resulting in a higher maintenance
burden.
Address the issue with a different approach, by creating a meson
environment for the Python scripts, and passing it to the
custom_target() functions. The environment only disables the bytecode
cache for now.
The diffstat shows an increase in code size. This is expected to be
offset by usage of the environment for more Python scripts, as well as
support of more variables in the environment.

The ipaCreate() function is the entry point to IPA modules. It is
declared in ipa_interface.h, and defined by each module. As the function
is defined with extern "C" linkage, the namespace in which it is
contained is not very relevant from a caller's point of view. For the
IPA module implementer, however, defining the function in the libcamera
namespace avoids adding an explicit libcamera:: prefix to the symbols
used by the function. This is why all IPA modules define their
ipaCreate() entry point in the libcamera namespace.
The ipa_interface.h file, however, declares the function in the global
namespace. This doesn't cause any issue at runtime, but will cause a
missing declaration warning when we enable them. To prepare for that,
move the function declaration to the libcamera namespace.

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.

In the existing meson scripts, an IPA mojom interface file may not be
built if:
- There are duplicate entries for the mojom file shared by different
pipeline handlers in pipeline_ipa_mojom_mapping, and
- The IPA is not listed first in pipeline_ipa_mojom_mapping, and
- The first listed IPA for the given mojom file is not selected in the
build.
Fix this by using a separate list of already built mojom files
(mojoms_built) instead of overloading use of the existing
ipa_mojom_files list. Now, ipa_mojom_files gets filled in outside of
the IPA list enumeration loop, this also guarantees the IPA
documentation gets built even if the pipeline is not selected.

To support this, add support for the skipHeader attribute for enums.
Like structs, it is only allowed in core.mojom.

For the purpose of testing serializing/deserializing Flags in function
parameters, add an enum class TestFlags and Flags<TestFlags> to some
function parameters, both for input and output and Signals.
While at it, update the ipa_interface_test.

Add Flags<E> as a supported type in the IPA interface.
It is used in mojom with the [flags] attribute. Any field or parameter
type E that is prefixed with the [flags] attribute will direct the code
generator to generate the type name "Flags<E>" and appropriate
serialization/deserialization code for Flags<E> instead of for E.
It is usable and has been tested in struct members, function input and
output parameters, and Signal parameters. This does not add support for
returning Flags as direct return values.
Additionally, the [scopedEnum] attribute can be used on enum
definitions, which will instruct the code generator to convert it to an
enum class instead of a raw enum.

Update CamHelper::getDelays() to return the sensor HBLANK delay. The
HBLANK delay is set to the same value as VBLANK delay for all sensors in
the Raspberry Pi IPA.
Return the HBLANK gain delay from the IPA to the pipeline handler, and
initialise DelayedControls to handle V4L2_CID_HBLANK with this delay
value.
As a drive-by, check that the V4L2_CID_HBLANK control is available when
calling IPARPi::configure().

Add fields for minimum and maximum line length (in units of pixels) to
the IPACameraSensorInfo structure. This replaces the existing lineLength
field.
Update the ipu3, raspberrypi and rkisp1 IPAs to use
IPACameraSensorInfo::minLineLength instead of
IPACameraSensorInfo::lineLength, as logically we will always want to use
the fastest sensor readout by default.
Since the IPAs now use minLineLength for their calculations, set the
starting value of the V4L2_CID_HBLANK control to its minimum in
CameraSensor::init().

Currently the pipeline handler advertises controls handled by the IPA
from a ControlInfoMap it manually constructs. This is wrong, as the IPA
module is the component that knows what controls it supports. Fix this
by moving the ControlInfoMap construction to the IPA module, and pass it
to the pipeline handler as a return value from the IPA init() function.

The ipa currently advertises a static ControlInfoMap to specify the available
controls and their limits. Fix this limitation by having the IPA populate a new
ControlInfoMap with updated limits for ExposureTime, AnalogueGain, and
FrameDurationLimits controls based on the current sensor mode. This new
ControlInfoMap is then returned back to the pipeline handler and available to
the application after a successful Camera::configure() call.
Before the first call to Camera::configure(), this ControlInfoMap provides some
reasonable default limits for ExposureTime, AnalogueGain, and
FrameDurationLimits. However, applications must not rely on these values, but
obtain the correct limits after the call to Camera::configure().

Currently the pipeline handler advertises controls handled by the IPA from a
static ControlInfoMap defined in the raspberrypi.h header. This change removes
this header file, and instead the IPA returns the ControlInfoMap to the pipeline
handler from the ipa::init() function. This is done to allow the IPA to adjust
the limits of the controls based on the sensor mode in a subsequent change.

The C structures used to serialize controls are currently defined in the
root namespace, which places them at the root level in the class list
generated by Doxygen. Move them to the libcamera namespace to fix that.
