As the Android framework sends to the camera device settings
incrementally (only the ones that change are updated), the CameraDevice
class in the Android camera HAL keeps a copy of the last received
settings to be able to apply controls to the libcamera Camera and to
populate metadata correctly.
When a valid 'camera3Request->settings' is provided, it gets saved to
'lastSettings_' but 'descriptor->settings_' is not initialized until
the next frame (assuming it does not contain more settings).
Fix this by assigning to 'descriptor->settings_' the last saved
settings unconditionally.

The Android CameraDevice class adds a sourceStream for each Mapped
stream requested by the framework.
When mapping multiple framework streams to the same sourceStream, the
implementation of CameraDevice::processCaptureRequest wrongly erases the
just added sourceStream from the list of streams to request to
libcamera.
Fix this by adding the stream instead of erasing it.

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.

Private members of the FrameBuffer class are split between FrameBuffer
and FrameBuffer::Private. There was no real justification for this
split, and keeping some members private in the FrameBuffer class causes
multiple issues:
- Future modifications of the FrameBuffer class without breaking the ABI
may be more difficult.
- Mutable access to members that should not be modified by applications
require a friend statement, or going through the Private class.
Move all remaining private members to the Private class to address the
first issue, and add a Private::metadata() function to address the

When a request completes, a debug message is generated to help

The printed number of streams is however the number of output buffers
requested by the camera framework, not the number of streams generated
by libcamera. In facts, some output buffers are generated by
post-processing, and not directly from the camera.
As the debug message prints the libcamera identifier for the Request, it
is more logical to print the number of streams generated by the camera
instead of the total number of streams.

Note that updateEntry() will fail if the entry was not yet added, and
addEntry() will fail is the entry was already added. They are silent
failures that cause unexpected values to find their way into the android
metadata instance.
Previously this helper was not necessary, as (with respect to the
current use case) the preview template generator would always add a key
so the other template generators that used the preview template as
boilerplate could reliably use updateEntry(). The preview template
generator will soon decide based on capabilities whether or not to add
keys, so the other template generators need a helper to decide whether
to use updateEntry() or addEntry().
For now only implement it for enums and arithmetic values, as they will

Both are less than capped minFrameDuration 1/30 fps (33333333.33ns).
