We have multiple methods which return an error code, mimicking the C++
API. Using exceptions is more natural in the Python API, so change all
those methods to raise an Exception instead.

Commit 66c618f378aa ("android: mm: generic: use
GRALLOC_HARDWARE_MODULE_ID") made libhardware a required dependency for
the Android camera HAL on non-Chrome OS platforms. This isn't an issue
for real devices, as Android provides libhardware, but it prevents
compile-testing the camera HAL on traditional Linux systems.
To restore the compile-test coverage, stub the libhardware function used
by the camera HAL when libhardware isn't found.

PlatformFrameBufferAllocator is an abstraction over gralloc.
Right now hardwareModule_ points towards a CAMERA_HARDWARE_MODULE_ID.
When gralloc_open() is called we observe:
libcamera: DEBUG HAL camera3_hal.cpp:75 Open camera gpu0
libcamera: ERROR Camera camera.cpp:524 Camera in Configured state trying acquire() requiring state Available
01-23 14:14:04.742 370 416 E libcamera: FATAL HAL generic_frame_buffer_allocator.cpp:105 gralloc_open() failed: -87
Which is wrong, gralloc_open() is attempting to re-open the camera HAL,
instead of the gralloc HAL.
Point to a GRALLOC_HARDWARE_MODULE_ID instead so that we can request
buffers from gralloc in android.
Note: this adds new dependencies on android's libhardware [1] and on libdl.

When iterating over enabled pipelines and IPA modules, libcamera
descends into subdirectories in a recursive manner, which involves
nested loops. Both the outer and inner loops use the same loop variable
named 'pipeline'. As the outer loop uses the variable after descending
into the inner directory, it ends up using an incorrect value. Fix it by
moving all use of the variable before the subdir() call, and add a
comment that warns about the issue to avoid reintroducing it.

Files opened internally in libcamera without the O_CLOEXEC file will
remain open upon a call to one of the exec(3) functions. As exec()
doesn't destroy local or global objects, this can lead to various side
effects. Avoid this by opening file descriptors with O_CLOEXEC for all
internal files.
The O_CLOEXEC flag should also be set when obtaining file handles from
the V4L2 VIDIOC_EXPBUF operation, but was missed during the updates to
both d942bdc913c5 ("libcamera: v4l2_device: openat(2) with O_CLOEXEC to

The STM32 contains a camera pipeline known as the DCMIPP (Digital
Camera-Memory Interface Pixel Processor) which receives data from a
parallel interface and dumps the post-processed data to memory. The
pipeline is capable of some processing in the form of downscaling
captured data through cropping or skipping the sensor's output.
The simple pipeline handler is quite capable of handling the DCMIPP
given its operation is handled entirely through configuring the pads
of a media graph, so add support for the driver to the pipeline's
supportedDevices array.

At generateConfiguration() a YUV/RGB pixel format is preferred for the
StillCapture/VideoRecording/Viewfinder roles, but currently there are no
guarantees in place that the sensor provides a non-Bayer bus format from
which YUV/RGB can be generated.
This makes the default configuration generated for those roles not to
work if the sensor is a RAW-only one.
To improve the situation split the configuration generation in two,
one for YUV modes and one for Raw Bayer mode.
StreamRoles assigned to a YUV mode will try to first generate a YUV
configuration and then fallback to RAW if that's what the sensor can
provide.
As an additional requirement, for YUV streams, the generated mode has to
be validated with the sensor to confirm the desired sizes can be
generated as the ISI cannot up-scale. In order to test a format use the
newly introduced CameraSensor::tryFormat().

As per the RAW format selection, the media bus format selection
procedure relies on the direct association of PixelFormat and media

As the ISI can generate YUV and RGB formats from any non-Bayer media
bus format, break out the YUV/RGB media bus format selection to a
separate function.
The newly introduced getYuvMediaBusFormat() tests a list of
known-supported media bus formats against the list of media bus
formats supported by the sensor and tries to prefer media bus
codes with the same encoding as the requested PixelFormat.

The current implementation of the ISI pipeline handler handles
translation of PixelFormat to media bus formats from the sensor
through a centralized map.
As the criteria to select the correct media bus code depends on if the
output PixelFormat is a RAW Bayer format or not, start by splitting
the RAW media bus code procedure selection out by adding a function
for such purpose to the ISICameraData class.
Add the function to the ISICameraData and not to the
ISICameraConfiguration because:
- The sensor is a property of CameraData
- The same function will be re-used by the ISIPipelineHandler
during CameraConfiguration generation.

It's possible to construct a Camera with an unsafe controlInfo_.
This is the case in the Simple pipeline, where the camera controls are
not populated.
With Simple, if we attempt to set a Control, we end up with a segfault
because the default constructor for ControlInfoMap doesn't
intialized idmap_ which is initialized at class declaration time as
const ControlIdMap *idmap_ = nullptr;
Add some safeguards in ControlInfoMap to handle this case.

In `udevNotify()`, constructing an std::string from the device's
associated action is unnecessary as it is only compared against static
strings, and for that purpose an std::string_view works just as well,
while being cheaper to construct.
In the same vein, an std::string_view can be used to store the device's
devnode initially, and the string construction can be deferred until it
is needed.
Furthermore, previously `udev_device_get_devnode()` was called twice.
The extra call is now removed.

Previously, after `addV4L2Device()` had seen all dependecies, it would
remove the `MediaDeviceDeps` object from the `pending_` list, which
would result in it being destroyed. However, there would still be
(dangling) pointers to this object in `devMap_` that were added in
`addUdevDevice()` (line 103). So remove the entry with the given devnum
when it is removed from the corresponding `MediaDeviceDeps` object.

The "shadows" constraint mode actually exists in a number of tuning
files, but had been omitted from the list of supported modes.

Clarify IPA's acronym by specifying what "IPA" stands for as part of the
ipa namespaces' "brief" doxygen-generated description. This allows
visitors to the docs to immediately have an idea of the purpose of the
IPA namespace at a glance. Because of the prevalence and importance of
the IPA namespace and functionality, the fact that it stands for "Image
Processing Algorithm" should be accessible to even casual perusers of
the docs.

Files opened internally in libcamera without the O_CLOEXEC file will
remain open upon a call to one of the exec(3) functions. As exec()
doesn't destroy local or global objects, this can lead to various side
effects. Avoid this by opening file descriptors with O_CLOEXEC for all
internal files.

Use the generalised focus statistics structure to compute the centre
window focus FoM value. This avoids needed to hard-code a specific
grid size.
Remove the focus reporting algorithm as the functionality is duplicated
by this bit of IPA code. Remove focus_status.h as it is no longer needed.

Remove any hard-coded assumptions about the target hardware platform
from the autofocus algorithm. Instead, use the "target" string provided
by the camera tuning config and generalised statistics structures to
determing parameters such as grid and region sizes.
Additionally, PDAF statistics are represented by a generalised region
statistics structure to be device agnostic.
These changes also require the autofocus algorithm to initialise
region weights on the first frame's prepare()/process() call rather
than during initialisation.

This change replaces all hard-coded arrays with equivalent std::vector

Generalise the contrast algorithm code by removing any hard-coded
assumptions about the target hardware platform. Instead, the algorithm
code creates a generic Pwl that gets returned to the IPA, where it gets
converted to the bcm2835 hardware specific lookup table.
As a drive-by, remove an unused mutex.

The algorithm uses the data type std::vector<std::array<double, 4>> to
represent the large sparse matrices that are XY (X, Y being the ALSC
grid size) high but with only 4 non-zero elements on each row.
Replace this slightly long type name by SparseArray<double>.
No functional changes.
