The ipu3_agc.h forward-declares the IPACameraSensorInfo structure, but
incorrectly declares it as a class. This causes a compilation error with
clang:
include/libcamera/ipa/core_ipa_interface.h:24:1: error: 'IPACameraSensorInfo' defined as a struct here but previously declared as a class; this is valid, but may result in linker errors under the Microsoft C++ ABI [-Werror,-Wmismatched-tags]

class IPACameraSensorInfo;

A new utils::Duration class is defined to represent a std::chrono::duration type
with double precision nanosecond timebase. Using a double minimises the loss of
precision when converting timebases. This helper class may be used by IPAs to
represent variables such as frame durations and exposure times.
An operator << overload is defined to help with displaying utils::Duration value
in stream objects. Currently, this will display the duration value in
microseconds.

Frame duration is hard-coded for CTS as per [1]. Ideally, to accurately
calculate the frame duration, it needs the VBLANK value from every
frame's exposure. However, this particular bit is yet to be implemented
in IPAIPU3.
Meanwhile, we can at least head in the right direction by not hard
coding the value, instead using the default VBLANK value as reported
by the sensor. Update the existing \todo, to use the derived VBLANK
value as and when it's available from each frame exposure.

Squash \todo by calculating line duration from IPACameraSensorInfo,
now passed in, to IPU3Agc::initialise().
Since line duration is now calculated from real values, store it as a
private member in IPU3Agc class. As a further step, replace the
associated global constant, kMaxExposureTime, with a private IPU3Agc
class member as well, and assign its value correspondingly in
IPU3Agc::initialise(), similar to previous precedence.

The return value from generateConfiguration() was not checked. Only assert
was added as a guard which checked if the size of the generated camera
config was equal to size of roles passed to it.
If the roles variable has an invalid/unsupported role, it will return
a nullptr and then trying to access a member on a nullptr for size comparison
will result in a segmentation fault. So, if the function returns a nullptr,
simply push an error message on GstBus and gracefully exit.

When compiling with optimization, gcc 9 and newer throw an unitialized

172 | unsigned int bdsIntHeight = static_cast<unsigned int>(bdsHeight);
Neither clang not gcc versions older than 9 complain. This seems to be
a false positive.
However, there's an obvious error in the code. The second while () loop
in the first part of calculateBDSHeight() modifies the bdsHeight
variable set by the first loop even if the second loop doesn't find a
suitable height. This can result in an incorrect bdsHeight value. Fix
this, which also gets rid of the compiler warning.

365 | return (guint8 *) g_memdup (data, size);
GLib has a mechanism to silence warnings introduced in newer versions,
to allow compilation without warnings on multiple versions of the
library. This is done by setting the GLIB_VERSION_MIN_REQUIRED macro to
the minimum GLib version required.
As we depend on GStreamer >= 1.14, set the minimum GLib version to 2.40.

This reverts commit 5b015e96ccdbcd87b4ba6484199652fec5cdb38a.
The ImgU pipe configuration debug is useful to test the correctness
of the parameters computation against the Intel Python script.
However, the number of debug messages which is printed out by the
configuration procedure is so high it floods the logs, up to the point
that starting the Android camera3 HAL, which tests several configurations
at startup, becomes so slow it is barely usable.
Revert the patch that adds the excessive debug statements, which are mostly
useful only when testing the configuration procedure.

On gcc versions older than 9, the file system library, used by the
Android camera HAL configuration file parser, is implemented in a
separate static library. Furthermore, on gcc 7, it's provided in the
std::experimental namespace. This breaks compilation of the HAL on gcc
7, and linking on gcc 8.
Fix the compilation issue by conditionally including
<experimental/filesystem> and creating a namespace alias in std, and the
link issue by linking to libstdc++fs on gcc versions older than 9.
The inclusion of <experimental/filesystem> is a bit of a hack, and when
we'll start using the file system library in another compilation unit,
we should then move all this to an internal helper to abstract the
compiler version.

The HAL layer was getting the min and max frame durations from the
camera, then rounding it to fps to report as available fps ranges. The
same min and max frame durations were then being reported as min and max
frame durations. Since the fps are integer values while the frame
durations are in ns, this caused a rounding error making it seem like we
were reporting an available max fps that was higher than what was
allowed by the minimum frame duration.
An example is if the minimum frame duration is reported as 33366700ns.
The HAL layer would then convert it to fps, which is 29.97, but it would
be rounded and reported as 30 fps. When 30 fps is converted to a frame
duration it is 33333333ns, which is less than the minimum frame duration
that we report. Thus the minimum frame duration that we report
contradicts the fps range that we report.
Fix this by recalculating the frame durations based on the rounded fps
values.
This allows the following CTS test to pass:

When stopping the camera worker, queuedRequest() calls may have queued
asynchronous function invocation messages to the worker thread, and some
of those messages may not have been processed yet. The messages will
stay in the thread's queue until the camera worker is restarted (when
the camera service will start a new capture session). At that point,
they will be dispatched, which will cause a crash due to the
CaptureRequest passed to processRequest() having been deleted by
CameraDevice::stop() calling descriptors_.clear().
Fix this by forcing dispatching of all function invocation messages when
stopping the camera worker thread. Note that this is inherently racy, as
more queueRequest() calls may arrive from the camera service while we're
stopping. This race condition will be addressed by a subsequent patch
series.

In the case of IPAs being external, building in-tree IPAs might be

CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).
As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.
Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

(core_ipa_interface.cpp). This will allow Doxygen to generate the
documentation for IPABuffer, IPASettings and IPAStream structures.
Since the .mojom files are placed in include/ directory, the .cpp file
will live in $sourcedir/src/libcamera/ipa/ - which can also contain
documentation for other mojom generated IPA interfaces in subsequent
commit.
Also hide the constructors in generated IPA interface from doxygen,
via #ifndef __DOXYGEN__. These constructors provide no major value in
documenting them, instead will spew out doxygen warnings during the
build.

When a thread stops, messages may be left in its message queue. Document
this in details, with a way to force processing of pending messages when
the thread is stopped.

The asynchronous signal delivery mechanism can't be used by application,
as it requires libcamera to be aware of the application event loop,
which has been dropped a long time ago. Drop the corresponding
documentation paragraph.

The Thread::dispatchMessages() function is meant to be called from
within the thread only. Catch incorrect usage with an ASSERT().

The Thread class is incorrectly documented as thread-safe, as the
dispatchMessages() function isn't thread-safe. Fix the documentation by
tagging individual functions as thread-safe as appropriate.

V4L2ControlId and V4L2ControlInfo are just convenience classes to
create ControlId and ControlInfo from v4l2_query_ext_control.
Therefore, there is no need of being a class. It is used only
from V4L2Device. This removes the classes and put the equivalent
functions of creating ControlId and ControlInfo in
v4l2_device.cpp.
