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".

Rename the private Stream class from V4L2M2MConverter::Stream to
V4L2M2MConverter::V4L2M2MStream. This is done to improve readability
of the code when we drop the handling of stream by indexes in a
subsequent patch.

The streams sanity check tries to determine if all the stream indexes
passed in outputs std::map<> are unique. However, since the data
container is std::map<>, all its keys (stream indexes in this case),
are already unique.
Instead, rectify the sanity check to ensure all the framebuffers passed
in the outputs std::map<> are unique to each index. Hence, no two stream
indexes should have same framebuffer. Update the comment to reflect
the change.

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.

The camera pipeline for MediaTek MT8365 consists of the following:
Raw sensor (+ external ISP) --> SENINF --> CAMSV30 --> DRAM
SENINF (SENsor INterFace) is a CSI-2 receiver.
CAMSV30 (Camera Simple Version) is a DMA Engine which bypasses
ISP3.0 and writes directly to DRAM.
Both SENINF and CAMSV30 are supported by V4L2 drivers.
MT8365 platform consists of a hardware converter called MDP which
supports up to three streams.

Move the simple converter implementation to a generic V4L2 M2M class
derived from the converter interface. This latter could be used by
other pipeline implementations and as base class for customized V4L2 M2M
converters.
