musl does not implement GNU basename extention and with latest musl
the prototype from string.h is also removed [1] which now results in
compile errors e.g.
../git/utils/ipu3/ipu3-pack.c:21:47: error: call to undeclared function 'basename'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
These utilities are using this function in usage() which is used just
before program exit. Always use the basename APIs from libgen.h which is
posix implementation

Black may not be represented as 0 pixel value for given hardware, it may
be higher. If this is not compensated then various problems may occur
such as low contrast or suboptimal exposure.
The black pixel value can be either retrieved from a tuning file for the
given hardware, or automatically on the fly. The former is the right
and correct method, while the latter can be used when a tuning file is
not available for the given hardware. Since there is currently no
support for tuning files in software ISP, the automatic, hardware
independent way, is always used. Support for tuning files should be
added in future but it will require more work than this patch.
The patch looks at the image histogram and assumes that black starts
when pixel values start occurring on the left. A certain amount of the
darkest pixels is ignored; it doesn't matter whether they represent
various kinds of noise or are real, they are better to omit in any case
to make the image looking better. It also doesn't matter whether the
darkest pixels occur around the supposed black level or are spread
between 0 and the black level, the difference is not important.
An arbitrary threshold of 2% darkest pixels is applied; there is no
magic about that value.
The patch assumes that the black values for different colors are the
same and doesn't attempt any other non-primitive enhancements. It
cannot completely replace tuning files and simplicity, while providing
visible benefit, is its goal. Anything more sophisticated is left for
future patches.
A possible cheap enhancement, if needed, could be setting exposure +
gain to minimum values temporarily, before setting the black level. In
theory, the black level should be fixed but it may not be reached in all
images. For this reason, the patch updates black level only if the
observed value is lower than the current one; it should be never
increased.
The purpose of the patch is to compensate for hardware properties.
General image contrast enhancements are out of scope of this patch.
Stats are still gathered as an uncorrected histogram, to avoid any
confusion and to represent the raw image data. Exposure must be
determined after the black level correction -- it has no influence on
the sub-black area and must be correct after applying the black level
correction. The granularity of the histogram is increased from 16 to 64
to provide a better precision (there is no theory behind either of those
numbers).

The current src/ipa/meson.build assumes the IPA name to match the
pipeline name. For this reason "-Dipas=simple" is used for the
Soft IPA module.
Auto exposure/gain and AWB implementation by Dennis, Toon and Martti.
Auto exposure/gain targets a Mean Sample Value of 2.5 following
the MSV calculation algorithm from:
https://www.araa.asn.au/acra/acra2007/papers/paper84final.pdf
Use CameraSensorHelper to convert the analogue gain code read from the
camera sensor into real analogue gain value. In the future this makes
it possible to use faster AE/AGC algorithm. Right now the CameraSensorHelper
lets us use the full range of analogue gain values.
If there is no CameraSensorHelper for the camera sensor in use, a
warning log message is printed.

This implementation offers a configure function + functions to gather
statistics on a line by line basis. This allows CPU based software
debayering to call into interleave debayering and statistics gathering

This implementation also allows specifying a window over which to gather

SharedMemObject class
The SharedMemObject class template contains a fair amount of inline code
that does not depend on the template types T. To avoid duplicating it in
every template specialization, split that code to a separate base
SharedMem class.
We don't define copy semantics for the classes (we don't need one at the
moment) and we make them non-copyable since the default copy constructor
would lead to use-after-unmap.

When file output is requested from cam app, it simply dumps the
processed data and it must be converted to a readable image format
manually. Let's add support for PPM output file format to make files
produced by cam directly readable by image display and processing
software.
For now, only BGR888 output format, which is the simplest one to use, is
supported but nothing prevents adding support for other output formats
if needed. Nevertheless, they would typically need byte reordering or
other conversions for PPM file format. It may be better to find a way to
dump the image data in other output formats directly using some of the
already existing file formats or raw file format converters.

When a valid 'camera3Request->settings' is provided, it gets saved to

The V4L2Subdevice class deals with streams in two places:
- In routing tables, streams as expressed as a pad number and a stream
number in a v4l2_subdev_route instance.
- In the format and selection get and set functions, streams as
expressed using the Stream structure, which binds the pad number and
stream number.
Expressing streams in different ways requires pipeline handlers and
other helpers to convert between the two representations. This isn't
much of an issue yet as libcamera has little stream-aware code, but it
is expected to increasingly become a burden.
To simplify the API, introduce a V4L2Subdevice::Route structure that
mimicks the kernel v4l2_subdev_route structure but represents streams as
V4L2Subdevice::Stream instances. This will improve seamless integration
of routes, formats and selection rectangles.

The main (and only at the moment) use case for the Routing::toString()
function is to print a representation of the routing table in a log
message. The function is implemented using an std::stringstream, and the
returned std::string is then inserted into an std::ostream. This is
inefficient. Replace the function with a specialization of the
operator<<() and use it in the caller.

Extend the V4L2Subdevice API with stream support for the functions that
get and set formats and selection rectangles. Add a Stream structure to
identify a subdev pad and stream, and use it to extend the V4L2Subdevice
functions that get and set formats and selection rectangles with stream
support.
To preserve the existing pad-based API, implement overloaded functions
that wrap the new stream-based API. This allows callers that are not
stream-aware to use a simpler pad-based API, instead of having to
explicitly set the stream number to 0 in all API calls.

The V4L2SubdeviceFormat::mbus_code member doesn't follow the libcamera
coding style as it should use camelCase. Fix it by renaming it to just
'code', to shorten lines in addition to fixing the coding style.

The V4L2SubdeviceFormat::bitsPerPixel() function is just a wrapper
around a MediaBusFormatInfo lookup. It made sense when the
MediaBusFormatInfo class was not exposed outside of the compilation
unit, but is now redundant. Drop it and use MediaBusFormatInfo in the
only caller.

Not all media bus formats describe image formats. Extend the
MediaBusFormatInfo class with a type member to indicate if the format
corresponds to image data or metadata, and add the (only) metatdata
format supported by the kernel to the known mediaBusFormatInfo.
The kernel doesn't (yet) have any metadata format specific to sensor
embedded data. This is being addressed in the V4L2 API. In preparation
for embedded data support, already introduce the EmbeddedData type here.
Corresponding formats will be added when available.

The V4L2SubdeviceFormatInfo structure, internal to the
v4l2_subdevice.cpp compilation unit, contains information about media
bus formats that will be useful in other parts of libcamera. To prepare
for this, expose the structure in the v4l2_subdevice.h header and turn
it into a class with a similar design as PixelFormatInfo.

To prepare for exposing the MediaBusFormatInfo structure as an internal
API, add a code member to the structure to store the media bus code.
This makes MediaBusFormatInfo usable standalone, without having to
externally associate the code related to the info.
The entries in the mediaBusFormatInfo map are becoming too long, so
split them on multiple lines.
While at it, swap the order of the members to match the PixelFormatInfo
class for consistency.

parseRectangles currently always parses Rectangle controls as an array
of Rectangles. This causes non-array Rectangle controls to not be parsed
correctly, as when the ControlValue is get()ed, the non-array assertion
will fail.
Set the ControlValue with a single Rectangle in case a single Rectangle
has been specified in the yaml capture script to fix that.
