Use the postfixed '_' member variable naming style for the
Camera3RequestDescriptor structure, which in turn ensures that variable
shadowing does not occur in the member initializer list of the

Add a CameraWorker class member to the CameraDevice class and
queue capture requests to it to delegate its handling. Start and
stop the CameraWorker when the libcamera::Camera is started or
stopped.
Tie the CaptureRequest lifetime to the Camera3RequestDescriptor's one
by storing it as unique_ptr<> in the descriptor to simplify handling
of request creation and deletion.

Pass the android camera3_stream_t, and a libcamera::StreamConfiguration
to identify the source and destination parameters of this stream.
Pass a CameraDevice pointer to the CameraStream constructor to allow
retrieval of the StreamConfiguration associated with the CameraStream.
Also change the format on which the CameraDevice performs checks to
decide if post-processing is required, as the libcamera facing format is
not meaningful anymore, but the Android requested format should be used
instead.

Make the CameraStream encoder a private unique pointer and require its
initialization at construction time. This ties the encoder lifetime to
the CameraStream it has been created with, allowing to remove the
CameraStream destructor.
This change dis-allow creating a CameraStream and set the Encoder later,
which shall not happen now that we create CameraStream once we have all
the required information in place.

The CameraDevice::streams_ vector of CameraStream instances is
currently mostly accessed by index. The current implementation
creates all the CameraStream during the first loop that inspects the
camera3_stream instances and then update the index of the
StreamConfiguration associated with the CameraStream during a second
loop that inspects MJPEG streams. A third loop creates the JPEG encoder
associated with camera streams that produce MJPEG format.
As the index-based association is hard to follow and rather fragile,
rework the creation and handling of CameraStream:
1) Make the StreamConfiguration index a constructor parameter and a
private struct member. This disallows the creation of CameraStream
without a StreamConfiguration index assigned.
2) Create CameraStream only after the associated StreamConfiguration
has been identified. The first loop creates CameraStream for non-JPEG
streams, the second for the JPEG ones after having identified the
associated StreamConfiguration. Since we have just created the
CameraStream, create the JPEG encoder at the same time instead of
deferring it.
This change removes all accesses by index to the CameraDevice::streams_
vector.
No functional changes intended, but this change aims to make the code
easier to follow and more robust.

The resolutions supported for the RAW formats cannot be tested from
a list of known sizes like the processed ones. This is mainly due to the
fact RAW streams are produced by capturing frames at the CSI-2 receiver
output and their size corresponds to the sensor's native sizes.
In order to obtain the RAW frame size generate a temporary
CameraConfiguration for the Role::StillCaptureRAW role and inspect the
map of StreamFormats returned by the pipeline handler.

The correct stream is obtained from the private data of the camera3_stream
associated with the camera3_buffer.

FrameBuffers have their lifetime tracked in the Camera3RequestDescriptor

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/.

According to the Android camera HALv3 documentation, the request
template metadata pack should not be modified after it is returned to
the camera stack from the HAL.
Currently, the same metadata pack is used for all types of template
request, without updating the capture intent there contained to match
the requested template type, as correctly reported by the
cros_camera_test test application.
In order to avoid modifying the single request template already returned
to the camera stack in order to update the capture intent it contains,
create a map that associates a dedicated template to each supported
capture type.

The CameraProxy is constructed with a Camera instance passed through a
shared pointer. It forwards it to the CameraDevice constructor, which
takes a reference used for the sole purpose of making an internal copy
of the shared pointer. Both constructors can thus take a const reference
instead of a value or a mutable reference. This optimises the
constructors slightly.
