Add V4L2 request support to the V4L2M2MConverter class. Extend the
functions related to buffer queuing with an optional request parameter
that gets passed to the lower layers.

With the upcoming addition of V4L2 requests support, the converters need
to keep a handle to the corresponding media device.
Prepare for that by changing the constructor parameter from a raw
pointer to a shared pointer.

Add to the Converter interface two functions used by pipeline handlers
to validate and adjust the converter input and output configurations
by specifying the desired alignment for the adjustment.
Add the adjustInputSize() and adjustOutputSize() functions that allows
to adjust the converter input/output sizes with the desired alignment.
Add a validateOutput() function meant to be used by the pipeline
handler implementations of validate(). The function adjusts a
StreamConfiguration to a valid configuration produced by the Converter.

Add a isConfigured() function to be able to check if a given stream was
configured in the converter. This is useful in pipelines to either query
device or stream specific crop bounds depending on whether the stream is
configured or not.

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
properties and to implement validation before the Camera gets
configured.

If the converter has cropping capability on its input, the interface
should support it by providing appropriate virtual functions. Provide
Feature::InputCrop in Feature enumeration for the same.
Provide virtual setInputCrop() and inputCropBounds() interfaces so that
the converter can implement its own cropping functionality.
The V4L2M2MConverter implements these interfaces of the Converter
interface. Not all V4L2M2M converters will have cropping ability
on its input, hence it needs to be discovered at construction time.
If the capability to crop is identified successfully, the cropping
bounds are determined during configure() time.

The Doxygen directive only requires qualifying header file names with a
path to differentiate between multiple header files with the same name.
Most file directives that refer to unambiguous files do not have a
libcamera/ and/or internal/ path prefix, but a few do, most likely due
to copy&paste. Drop the prefix in those few files for consistency.

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".

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.

Also make the descriptions of ConverterFactoryBase::compatibles() and

The ConverterFactoryBase::create() function returns a nullptr when no
converter is found. The only caller, SimpleCameraData::init(), checks if
the converter is valid with isValid(), but doesn't check if the pointer
is null, which can lead to a crash.
We could check both pointer validity and converter validity in the
caller, but to limit the complexity in callers, it is better to check
the converter validity in the create() function and return a null
pointer when no valid converter is found.

Declare a converter Abstract Base Class intended to provide generic
interfaces to hardware offering size and format conversion services on
streams. This is mainly based on the public interfaces of the current
converter class implementation found in the simple pipeline handler.
The main change is the introduction of loadConfiguration() function
which can be used by the concrete implementation to load hardware
specific runtime parameters defined by the application.
