The PipelineHandlerFactoryBase class has a name that is propagated to
the PipelineHandler instance it creates.
In present implementation, this name comes from the
REGISTER_PIPELINE_HANDLER registration macro. It corresponds to the
stringified name of the PipelineHandler derived class. Therefore,
PipelineHandler factories and instances names can be quite long such as
"PipelineHandlerRkISP1".
A libcamera user may have to explicitly refer to a PipelineHandler name
for configuration purpose: one usage of the name can be to define a
pipeline handlers match list and their priorities. It is desired, for
user convenience, to use a short name to designate a pipeline handler.
Reusing the short pipeline names already defined in the meson option
files is an existing and consistent way of naming pipelines.
This change adds an explicit name parameter to the
REGISTER_PIPELINE_HANDLER registration macro. That parameter is used to
define the name of a pipeline handler factory, instead of the current
pipeline handler class name.
Each pipeline registration is updated accordingly. The short name
assigned corresponds to the pipeline directory name in the source tree.
It is consistent with pipelines names used in meson.
Changing the pipeline name has an impact on the IPA modules: each module
defines a IPAModuleInfo structure. This structure has a pipelineName
member defining the pipeline handler name it shall match with.
Therefore, each internal IPA module definition has to be changed to have
its IPAModuleInfo pipelineName name updated with the short pipeline
handler name.
In addition to this pipelineName member, the IPAModuleInfo structure
also has a name member, associated to the IPA module name. Having
renamed the pipelines to a short name, the pipeline name and the IPA
module names of the IPAModuleInfo structure are the same: for in-tree
IPA, they correspond to the respective pipeline and IPA subdirectories
in the source tree. However the IPA name could be different, for
instance with a close source IPA implementation built out-of-tree. Thus,
it makes sense to keep the IPA name in that structure, as the 2
definitions may not always be redundant.

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.

DmaHeap class is useful outside the RPi pipeline handler too.
Move dma_heaps.h and dma_heaps.cpp to common directories. Update
the build files and RPi vc4 pipeline handler accordingly.

The V4L2SubdeviceFormat::mbus_code member doesn't follow the libcamera

When validating a stream, and no valid packed pixel format can be
found, see if an unpacked format can be used instead.
This is particularly helpful for 8 (and 16) bit raw formats, where
asking for a packed format would previously have failed. Now the
configuration will be adjusted to give you a format (in fact, the only
format) that will work.

Vc4CameraData::findMatchBuffers() may return successfully with a null
embedded buffer, in which case the embedded buffer id would be left
uninitialized.
Without this change, libcamera v0.2.0 usually crashes for me with an
assertion error:
ipa_base.cpp:397 assertion "it != buffers_.end()" failed in prepareIsp()

If no ISP output streams are configured, the ISP output count is skipped
for the the low res stream, and causes the drop frame logic to fail
because of a count mismatch. This in-turn stops any requests from
completing correctly.
Fix this by ensuring the low res output is counted correctly when no ISP
output streams are configured.

If the pipeline runs out of embedded data buffers, then it will pass
the frame to the IPA without the metadata. The IPA then has to use the
delayed controls as inputs to the algorithms. This can cause problems
with the subsequent algorithms if the sensor did not action the
controls, especially with the autofocus as that doesn't have controls
which can be passed in lieu of the metadata.
Reduce the likelihood of this by increasing the number of embedded data
buffers, as they are small so a generous number can be allocated.

Move the handling of Bayer order changes due to flips to run before
platformValidate(). This removes the need for this code to be split
between platformValidate() and validate() as it is right now.
Also add some validation to ensure the vc4 pipeline handler only
supports CSI2 packing or no packing.

Add a new RequiresMmap flag to the RPi::Stream class indicating that
buffers handled by the stream must be mmapped after allocation and
cached internally.
Add a new member function getBuffer(id) which can be used to obtain the
mapped buffers for a given buffer id.
Add a new member function acquireBuffer() which can be used to obtain
any mapped buffer that has not already been acquired by the caller.
As a drive-by, add the <algorithm> header to rpi_stream.cpp as it is
needed for the std::find_if() function.

This commit simplifies the validate() and configure() calls in the
pipeline handler in a number of ways:
- Determine the V4L2DeviceFormat structure fields for all streams
in validate(), cache them and reuse in configure() instead of
re-generating this structure multiple times.
- Remove setting a default pixel format in validate(), this code patch
will not be used.
- Use the recently added updateStreamConfig() and toV4L2DeviceFormat()
helpers to populate fields in the V4L2DeviceFormat and StreamConfiguration
structures to reduce code duplication.

Currently, the stream configuration is stored in two vectors, rawStreams
and outStreams for convenience. However, these vectors are constructed
in both platformValidate() and platformConfigure().
This change caches these vectors in the RPiCameraConfiguration class to
construct them only once in platformValidate().
Pass a pointer to the current configuration to platformValidate() and
platformConfigure() so that they can access the streams vectors.

Handle the SensorConfiguration provided by the application in the
pipeline validate() and configure() call chains.
During validation, first make sure SensorConfiguration is valid, then
handle it to compute the sensor format.
For the VC4 platform where the RAW stream follows the sensor's
configuration adjust the RAW stream configuration to match the sensor
configuration.

Create a new PipelineHandlerBase class that handles general purpose
housekeeping duties for the Raspberry Pi pipeline handler. Code the
implementation of new class is essentially pulled from the existing
pipeline/rpi/vc4/raspberrypi.cpp file with a small amount of
refactoring.
Create a derived PipelineHandlerVc4 class from PipelineHandlerBase that
handles the VC4 pipeline specific tasks of the pipeline handler. Again,
code for this class implementation is taken from the existing
pipeline/rpi/vc4/raspberrypi.cpp with a small amount of
refactoring.
The goal of this change is to allow third parties to implement their own
pipeline handlers running on the Raspberry Pi without duplicating all of
the pipeline handler housekeeping tasks.
