The PipelineHandler::generateConfiguration() function allocates a
CameraConfiguration instance and returns it. The ownership of the
instance is transferred to the caller. This is a perfect match for a
std::unique_ptr<>, which the Camera::generateConfiguration() function
already returns. Update PipelineHandler::generateConfiguration() to
match it. This fixes a memory leak in one of the error return paths in
the IPU3 pipeline handler.
While at it, update the Camera::generateConfiguration() function
documentation to drop the sentence that describes the ownership
transfer, as that is implied by usage of std::unique_ptr<>.

The limits for the shutter speed and analogue gain are stored in
IPASessionConfiguration::agc. While they're related to the AGC, they are
properties of the sensor, and are stored in the session configuration by
the IPA module, not the AGC algorithm. Move them to the

releaseBuffers() unconditionally calls ioctl(REQBUFS, 0) to release device
buffer allocations through the close() and class destructor functions. If
another libcamera process is running concurrently with a different sensor, it
would cause the ioctl to fail in the kernel because the buffer queue is owned
owned by the other process. This in turn would cause libcamera to generate an
error log message.
Fix this by ensuring the releaseBuffers() only calls ioctl(REQBUFS, 0) if there
have been buffers previously allocated by the device. This is done by testing
the presense of the V4L2BufferCache in the object.

Meson introduces a .replace() method in version 0.58.0. However we aim
to restrict ourselves to 0.56 meson features, as released by Debian
stable.
The recent introduction of release management infrastructure makes use
of the .replace() method to fix up the version string when there is a
mis-match between the release version and any (lack) of tags in the git
version description. This breaks when built on systems with only meson
0.56.
Refactor this to use a concatenation of the project version and a
stripped git version to regenerate the full source version string that
will be reported by libcamera.

Android 11's toolchain does not support std::filesystem, but
camera_hal_config.cpp currently uses it. Remove references to
std::filesystem in order to support Android <= 11.
This adds a very small difference in behaviour, as File::exist() will
return true for special files (pipes, character or block devices, ...)
while std::filesystem::is_regular_file() doesn't, but I consider this
to be a corner case that doesn't matter much.

Each declaration of a LogCategory will create a new LogCategory, and
will be stored in an unordered_set Logger::categories_. This means that
when a plugin .so is unloaded and loaded, as happens when destructing
and creating a CamereManager, we'll get duplicate categories.
The Logger::registerCategory docs say "Log categories must have unique
names. If a category with the same name already exists this function
performs no operation.". The code does not comply with this.
We solve the issue with two changes:
Change the unordered_set to a vector for simplicity, as there's no need
for an unordered_set.
Instead of using the LogCategory constructor to create new categories in
_LOG_CATEGORY() macro, use a factory method. The factory method will
return either an existing LogCategory if one exists with the given name,
or a newly created one.

LogCategory just stores the char * that was given to it in the
constructor, i.e. it refers to memory "outside" LogCategory. If the
LogCategory is defined in a .so that is unloaded, then it leads to the
LogCategory pointing to freed memory, causing a crash.
Fix this by taking a copy of the name by using a std::string instead of
just storing the pointer.
