Change the parameter type of `generateConfiguration()` from `const std::vector&`
to `libcamera::Span`. A span is almost always preferable to a const vector ref
because it does not force dynamic allocation when none are needed, and it allows
any contiguous container to be used.
A new overload is added that accepts an initializer list so that
cam->generateConfiguration({ ... })
keeps working.
There is no API break since a span can be constructed from a vector
and the initializer list overload takes care of the initializer lists,
but this change causes an ABI break.

Add a new helper function PipelineHandler::configurationFile() that returns
the full path of a named configuration file. This configuration file may be read
by pipeline handlers for platform specific configuration parameters on
initialisation.
The mechanism for searching for the configuration file is similar to the IPA
configuration file:
- In the source tree if libcamera is not installed
- Otherwise in standard system locations (etc and share directories).
When stored in the source tree, configuration files shall be located in a 'data'
subdirectory of their respective pipeline handler directory.

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<>.

libcamera implements a pipeline handler locking mechanism based on
advisory locks on media devices, to prevent concurrent access to cameras
from the same pipeline handler from different processes (this only works
between multiple libcamera instances, as other processes won't use
advisory locks on media devices).
A side effect of the implementation prevents multiple cameras created by
the same pipeline handler from being used concurrently. Fix this by
turning the PipelineHandler lock() and unlock() functions into acquire()
and release(), with a use count to replace the boolean lock flag. The
Camera class is updated accordingly.
As a consequence of this change, the IPU3 pipeline handler will fail to
operate properly when the cameras it exposes are operated concurrently.
The android.hardware.camera2.cts.MultiViewTest#testDualCameraPreview
test fails as a result. This should be fixed in the IPU3 pipeline
handler to implement mutual exclusion between cameras.

Provide a call allowing requests to be registered and associated with
the pipeline handler after being constructed by the camera.
This provides an opportunity for the PipelineHandler to connect any
signals it may be interested in receiving for the request such as
getting notifications when the request is ready for processing when
using a fence.
While here, update the existing usage of the d pointer in
Camera::createRequest() to match the style of other functions.

The MediaDevice lock is meant to prevent concurrent usage of multiple
cameras from the same pipeline handlers. As media devices are acquired
by pipeline handlers, we can't have multiple pipeline handlers trying to
lock the same media device. The recursive locking detection can thus be
moved to the pipeline handler. This simplifies the media device
implementation that now implements true lock semantics, and prepares for
support of concurrent camera usage.

libcamera: IPAProxy, IPAManager: Switch to one-proxy-per-pipeline scheme
IPAProxy is changed in two major ways:
- Every pipeline has its own proxy, to support each pipeline's IPA
interface
- IPAProxy implementations always encapsulate IPA modules, and switch
internally for isolation or threaded
The IPAProxy registration mechanism is removed, as each pipeline will
have its own proxy, so the pipeline can pass the specialized class name
of the IPAProxy to the IPAManager for construction.
IPAManager is changed accordingly to support these changes:
- createIPA is a template function that takes an IPAProxy class, and
always returns an IPAProxy
- IPAManager no longer decides on isolation, and simply creates an
IPAProxy instance while passing the isolation flag
Consequently, the old IPAProxy classes (IPAProxyThread and
IPAProxyLinux) are removed. The IPAInterfaceTest is updated to use
the new IPAManager interface, and to construct a ProcessManager as no
single global instance is created anymore.

The V4L2 compatibility layer uses devnum to match video device nodes to
libcamera Cameras. Some pipeline handlers don't report a devnum for
their camera, which prevents the V4L2 compatibility layer from matching
video device nodes to these cameras. To fix this, we first allow the
camera manager to map multiple devnums to a camera. Next, we walk the
media device and entity list and tell the camera manager to map every
one of these devnums that is a video capture node to the camera.
Since we decided that all video capture nodes that belong to a camera
can be opened via the V4L2 compatibility layer to map to that camera, it
would cause confusion for users if some pipeline handlers decided that
only specific device nodes would map to the camera. To prevent this
confusion, remove the ability for pipeline handlers to declare their own
devnum-to-camera mapping. The only pipeline handler that declares the
devnum mapping is the UVC pipeline handler, so remove the devnum there.
We considered walking the media entity list and taking the devnum from
just the one with the default flag set, but we found that some drivers
(eg. vimc) don't set this flag for any entity. Instead, we take all the
video capture nodes (entities with the sink pad flag set).

guards would clash. Rename the header guards of internal headers to
prevent any issue.

The libcamera internal headers are located in src/libcamera/include/.
The directory is added to the compiler headers search path with a meson
include_directories() directive, and internal headers are included with
(e.g. for the internal semaphore.h header)
#include "semaphore.h"
All was well, until libcxx decided to implement the C++20
synchronization library. The __threading_support header gained a
#include <semaphore.h>
to include the pthread's semaphore support. As include_directories()
adds src/libcamera/include/ to the compiler search path with -I, the
internal semaphore.h is included instead of the pthread version.
Needless to say, the compiler isn't happy.
Three options have been considered to fix this issue:
- Use -iquote instead of -I. The -iquote option instructs gcc to only
consider the header search path for headers included with the ""
version. Meson unfortunately doesn't support this option.
- Rename the internal semaphore.h header. This was deemed to be the
beginning of a long whack-a-mole game, where namespace clashes with
system libraries would appear over time (possibly dependent on
particular system configurations) and would need to be constantly
fixed.
- Move the internal headers to another directory to create a unique
namespace through path components. This causes lots of churn in all
the existing source files through the all project.
The first option would be best, but isn't available to us due to missing
support in meson. Even if -iquote support was added, we would need to
fix the problem before a new version of meson containing the required
support would be released.
The third option is thus the only practical solution available. Bite the
bullet, and do it, moving headers to include/libcamera/internal/.
