There is a possibility that an out-of-order completion of capture
request happens by calling process_capture_result() directly on error
paths. The framework expects that errors should be notified as soon as
possible, but the request completion order should remain intact.
An existing instance of this is abortRequest(), which sends the capture
results on flushing state, without considering order-of-completion.
Since we have a queue of Camera3RequestDescriptor tracking each
capture request placed by framework to libcamera HAL, we should be only
sending back capture results from a single location, by inspecting
the queue. As per the patch, this now happens in
CameraDevice::sendCaptureResults().
Each descriptor is now equipped with its own status to denote whether
the capture request is complete and ready to be send back to the
framework or needs to be waited upon. This ensures that the order of
completion is respected for the requests.
Since we are fixing out-of-order request completion in abortRequest(),
change the function to read from the Camera3RequestDescriptor directly,
instead of camera3_capture_request_t. The descriptor should have all the
information necessary to set the request buffers' state to error.

The descriptors_ map holds Camera3RequestDescriptor(s) which are
per-capture requests placed by the framework to libcamera HAL.
CameraDevice::requestComplete() looks for the descriptor for which the
camera request has been completed and removes it from the map.
Since the requests are placed in form of FIFO and the framework expects
the order of completion to be FIFO as well, this calls for a need of
a queue rather than a std::map.
This patch still keeps the same lifetime of Camera3RequestDescriptor as
before i.e. in the requestComplete(). Previously, a descriptor was
extracted from the map and its lifetime was bound to requestComplete().
The lifetime is kept the same by manually calling .pop_front() on the
queue. In the subsequent commit, this is likely to change with a
centralized location of dropping descriptors from the queue for request
completion.

Acquire fences for streams of type Mapped generated by
post-processing are not correctly handled and are currently
ignored by the camera HAL.
Fix this by adding CameraStream::waitFence(), executed before
starting the post-processing in CameraStream::process().
The change applies to all streams generated by post-processing (Mapped
and Internal) but currently acquire fences of Internal streams are
handled by the camera worker. Postpone that to post-processing time by
passing -1 to the Worker for Internal streams.
Also correct the release_fence handling for failed captures, as the
framework requires the release fences to be set to the acquire fence
value if the acquire fence has not been waited on.

All libcamera headers are meant to be installed in
${prefix}/include/libcamera/libcamera, with pkgconfig specifying the
include directory as `-I ${prefix}/include/libcamera`. Applications then
include the headers with `#include <libcamera/camera.h>`.
The base and ipa headers are meant to be installed in subdirectories of
the libcamera headers directory, but are mistakenly installed one level
too high, in ${prefix}/include/libcamera. This leads to compilation
failures when including the base or ipa header.
Fix this by setting the meson libcamera_include_dir variable to the
libcamera headers directory. All other header paths are derived from
that variable and are now correct.

The libcamera and libcamera-base libraries are currently unversioned, but
donwstream users expect these to have a proper SONAME version in order to
package them.
A stable release has not yet happened because the project is still under
development and the API/ABI might change. But having a versioned SONAME
would allow distributions to package libcamera, without the need to add
any downstream patch to set the version.
Since the "0.0.0" version is already used in different places, let's also
use that as the library version. The meson build system will use the first
part of the version ("0") as the SONAME version, which is aligned with the
convention used by other projects:
$ ls /lib64/libcamera*so* -1
/lib64/libcamera-base.so
/lib64/libcamera-base.so.0
/lib64/libcamera-base.so.0.0.0

The Camera3RequestDescriptor containing the capture request is added to
the descriptors_ map after a call to CameraWorker::queueRequest(). This
is a race condition since CameraWorker::queueRequest() queues requests
to libcamera::Camera asynchronously. The requests may thus complete
before they get added to descriptors_, in which case requestComplete()

Two independent instances of the ControlSerializer class are in use at
the IPC boundaries, one in the Proxy class that serializes data from the
pipeline handler to the IPA, and one in the ProxyWorker which serializes
data in the opposite direction.
Each instance operates autonomously, without any centralized point of
control, and each one assigns a numerical handle to each ControlInfoMap
it serializes. This creates a risk of potential collision on the handle
values, as both instances will use the same numerical space and
are not aware of what handles has been already used by the instance "on
the other side".
To fix that, partition the handles numerical space by initializing the
control serializer with a seed according to the role of the component
that creates the serializer and increment the handle number by 2, to
avoid any collision risk.
While this is temporary and rather hacky solution, it solves an issue
with isolated IPA modules without too much complexity added.

The ControlInfo class was originally designed to only transport
the control's minimum and maximum values which represent the control's
valid limits.
Later the default value of the control has been added to the ControlInfo
class, but the control serializer implementation has not been updated
accordingly.
This causes issues in IPA modules making use of ControlInfo::def() as,
when running in isolation, they would receive 0.
Fix that by serializing and deserializing the additional ControlValue
and update the protocol description accordingly.

When a ControlList is deserialized, the code searches for a valid
ControlInfoMap in the local cache and use its id map to initialize the
list. If no valid ControlInfoMap is found, as it's usually the case
for lists transporting libcamera controls and properties, the globally
defined controls::controls id map is used unconditionally.
This breaks the deserialization of libcamera properties, for which a
wrong idmap is used at construction time.
As the serialization header now transports an id_map_type field, store
the idmap type at serialization time, and re-use it at
deserialization time to identify the correct id map.
Also make the validation stricter by imposing to list of V4L2 controls to
have an associated ControlInfoMap available, as there is no globally
defined idmap for such controls.
To be able to retrieve the idmap associated with a ControlList, add an
accessor function to the ControlList class.
It might be worth in future using a ControlInfoMap to initialize the
deserialized ControlList to implement controls validation against their
limit. As such validation is not implemented at the moment, maintain the
current behaviour and initialize the control list with an idmap.

When running the IPA in isolated mode, each side of the IPC boundary
has an instance of the ControlSerializer class which is used to
serializer/deserialize controls before transmitting them on the wire.
The IPAProxyWorker, which creates and manages the process the IPA runs in,
does not reset its ControlSerializer upon an IPA::configure() call, while
the IPAProxy does, effectively creating a misalignment between the
two sides of the fence.
This obviously creates issues as one side of the IPC runs with a
populated and possibly stale cache of ControlInfoMap references, while the
other side gets reset every time a new configuration is applied to the
Camera.
Fix that by resetting the IPAProxyWorker ControlSerializer on an
IPA configure() call.
This change fixes an issue which is easily triggered by running two
consecutive capture sessions with the IPA running in isolated mode:

The IPA::configure() function has an IPAConfigInfo parameters which
contains a map of numerical indexes to ControlInfoMap instances.
This is a leftover of the old IPA protocol, where it was not possible to
specify a rich interface as it is possible today and each entity
ControlInfoMap was indexed by a numerical id and stored in a map.
Now that the IPA interface allows to specify parameters by name, drop the
map and send the sensor's control info map only.
If we'll need more ControlInfoMap to be shared with the IPA, a new parameter
can be added to IPAConfigInfo.

In gstreamer, when elements are created, usually a floating [1]
reference is returned which simply means, there is no ownership
transfer (yet). Once can simply check for NULL and return through
an error path, without bothering to clean up. Hence, g_autoptr is
not much of help here.
If the NULL checks have been passed successfully, elements are ready
to use. However, we must claim ownership/reference it before using
them via g_object_ref_sink().
This patch build upon this principle and removes the g_autoptr
from gstreamer test base class (gstreamer_test.cpp) whereever
necessary to tide up the code.

Add libatomic dependency which is needed since the addition of the base
support library in commit 27aff949fbc1 ("libcamera/base: Move extended
base functionality") to avoid the following build failure:

The V4L2 compatibility layer test includes a list of supported devices,
as V4L2 compatibility isn't officially supported with all devices yet.
If no supported device is present, the test reports success, while it
actually hasn't run. Report it being skipped in that case.

The ipa_data_serializer_test is configured to be able to run in parallel
with other tests.
If the test tries to acquire the VIMC sensor B while it is in use, it
would skip require skipping the test.
Instead, inform meson that it can not be run in parallel to ensure that
the test is able to obtain the resources it requires for execution.

A kernel bug can lead to unexpected buffers being dequeued where we
haven't entered the buffer in our queuedBuffers_ list.
This causes invalid accesses if not handled correctly within libcamera,
and while it is a kernel issue, we can protect against unpatched
kernels to provide a more suitable error message.
This is fixed in the kernel by commit c592b46907ad ("media:
videobuf2-core: dequeue if start_streaming fails") [0]
[0] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c592b46907ad
Handle unexpected buffers by returning a nullptr, and move cache
management after the validation of the buffer.

The incoming params buffer may contain uninitialised data, or the
parameters of previously queued frames. Clearing the entire buffer
may be an expensive operation, and the kernel will only read from
structures which have their associated use-flag set.
It is the responsibility of the algorithms to set the use flags
accordingly for any data structure they update during prepare().
Clear the use flags of the parameter buffer before passing the buffer
to the algorithms during their prepare() operations.

While the distribution is unspecified, The README.rst gives
debian/ubuntu named dependencies for all except the android
requirements.
Update the android dependencies to match the others, by showing that the
-dev package is required.

The current parsing takes the last result of split, which works for the
former, but not the latter. Take the second result of split instead, and
strip away any commas.
