gralloc.h is a very old API that has been deprecated at least since
Android P (9).
Switch over to a higher level abstraction of gralloc from libui, which
is compatible with Android 11 and up.
Libui:
* is provided in the VNDK (so it's available to vendors).
* is also used in the camera vts test named VtsAidlHalCameraProvider_TargetTest.
Notes:
* GraphicsBufferAllocator being a Singleton, buffer lifecycle
management is easier.
* The imported headers from Android generate the -Wextra-semi warning.
To avoid patching the files, a pragma has been added before inclusion.
* libdl was used for dlclosing() the legacy hal, so the dep has been dropped

The Android HAL has quite some Android-specific dependencies (such as
libhardware) which are not part of regular linux distributions.
To compile-test the HAL on a Linux x86 system, we have added some stubs.
This means that each time we add a new Android specific dependency, we need to
write an associated stub for it, which can get tricky, especially for complex
C++ classes such as GraphicBufferAllocator.
It would be easier if we could import the includes and the required libraries we
need from Android so that we can build-test the HAL.
The Vendor Native Development Kit (VNDK) provides all the libraries
that a vendor service (such as the libcamera HAL) can link against.
Add the VNDK as a subproject of libcamera and add the necessary meson bits so
that we can compile test the Android HAL on linux without having to stub
anything.

When building with custom STLs [1], meson will pass -nostdlib++ to the compiler,
which will conflict with the -stdlib=libc++ flag:

gralloc.h is a very old API that has been deprecated at least since
Android P (9).
Devices are encouraged to switch over to HIDL interface named
android.hardware.graphics.allocator@<VERSION>, where <VERSION> can be
2.0 ,3.0 or 4.0.
This is mandatory since Android Q (10) [1]
Fortunately, Android provides an abstraction on top of
android.hardware.graphics.allocator which is compatible with each
version.
This abstraction is implemented in libui, which is available in the
VNDK.
Import all necessary headers from AOSP and switch over the
generic_frame_buffer_allocator to use GraphicBufferAllocator.
This series has been build-tested on a linux host and functionally
tested on an AM62x SK EVM with Android 13. (preview and capture).

Use the compiler.get_define() function to get the value of

the code, but also guarantees to return the actual value of
_FORTIFY_SOURCE, even if defined through other means than through the

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.

Whenever we run Agc::process(), we store the most recent total

With these values we can apply the channel constraints after

A channel constraint is somewhat similar to the upper/lower bound
constraints that we use elsewhere, but these constraints apply between
multiple AGC channels. For example, it lets you say things like "don't
let the channel 1 total exposure be more than 8x that of channel 0",
and so on. By using both an upper and lower bound constraint, you
could fix one AGC channel always to be a fixed ratio of another.
Also read a vector of them (if present) when loading the tuning file.

The switchMode, prepare and process methods are updated to implement
multi-channel AGC correctly:
* switchMode now invokes switchMode on all the channels (whether
active or not).
* prepare must find what channel the current frame is, and run on
behalf of that channel.
* process updates the most recent DeviceStatus and statistics for the
channel of the frame that has just arrived, but generates updated
values working through the active channels in round-robin fashion.
One minor detail in process is that we don't want to change the
DeviceStatus metadata of the current frame, so we now pass this to the
AgcChannel's process method, rather than letting it find the
DeviceStatus in the metadata.

This commit does the basic reorganisation of the code in order to
implement multi-channel AGC. The main changes are:
* The previous Agc class (in agc.cpp) has become the AgcChannel class
in (agc_channel.cpp).
* A new Agc class is introduced which is a wrapper round a number of
AgcChannels.
* The basic plumbing from ipa_base.cpp to Agc is updated to include a
channel number. All the existing controls are hardwired to talk
directly to channel 0.
There are a couple of limitations which we expect to apply to
multi-channel AGC. We're not allowing different frame durations to be
applied to the channels, nor are we allowing separate metering
modes. To be fair, supporting these things is not impossible, but
there are reasons why it may be tricky so they remain "TBD" for now.
This patch only includes the basic reorganisation and plumbing. It
does not yet update the important methods (switchMode, prepare and
process) to implement multi-channel AGC properly. This will appear in
a subsequent commit. For now, these functions are hard-coded just to
use channel 0, thereby preserving the existing behaviour.

Usage of pip3 to install meson may result in a different meson version
available for the local user and for root. This causes issues when
running `meson install` (directly or through `ninja install`):
Installing to a system location will request elevated privileges and use
the system meson version to install files, which may fail to unpickle
data pickled with the meson version for the local user.
As all major distributions now provide a recent-enough version of meson,
usage of pip3 is not longer needed in most cases, and shouldn't be
recommended. Drop it.
While at it, update the version of meson listed in the documentation to
match the required version.

The Agc::process() function returns an AgcStatus object in the
metadata as before, but Agc::prepare() is changed to return the values
it computes in a separate AgcPrepareStatus object (under the new tag
"agc.prepare_status").
The "digitalGain" and "locked" fields are moved from AgcStatus to

Theme error:

Reason: UndefinedError("'style' is undefined")
The recommended replacement is 'styles[-1]'. However, this resolves to
'_static/css/theme.css', which is part of the 'css_styles' variable, and
results in the stylesheet being included twice. To avoid that and fix
