When SoftwareIsp stops, input and output buffers queued to it may not
yet be fully processed. They will be eventually returned but stop means
stop, there should be no processing related actions invoked afterwards.
Let's stop forwarding processed output buffers from the SoftwareIsp
slots once SoftwareIsp is stopped. Let's track the queued output
buffers and mark those still pending as cancelled in SoftwareIsp::stop
and return them to the pipeline handler.
Dealing with input buffers is addressed in a separate patch.

Software ISP runs debayering in a separate thread and debayering may
emit statsReady when software ISP (including the IPA) is being stopped.
The signal waits in a queue and gets invoked later, resulting in an
assertion error when attempting to invoke a method on the stopped IPA:
FATAL default soft_ipa_proxy.cpp:456 assertion
"state_ == ProxyRunning" failed in processStatsThread()
Let's prevent this problem by forwarding the ISP stats signal from
software ISP only when the IPA is running. To track this,
SoftwareISP::running_ variable is introduced.
Making processing of the other signals in SoftwareISP more robust is
addressed in the followup patches.

Log categories may be added from any thread, so it is important to
synchronize access to the `Logger::categories_` list between its two
users: category creation (by LogCategory::create(), which calls
Logger::findCategory() and Logger::registerCategory()); and log level
setting (by Logger::logSetLevel()).
The LogCategory::create() function uses a mutex to serialize category
creation, but Logger::logSetLevel() can access `Logger::categories_`
concurrently without any protection. To fix the issue, move the mutex to
the Logger class, and use it to protect all accesses to the categories
list. This requires moving all the logic of LogCategory::create() to a
new Logger::findOrCreateCategory() function that combines both
Logger::findCategory() and Logger::registerCategory() in order to make
the two operations exacute atomically.

The severity of a log category may be changed from a different thread,
so it is important to ensure that the reads and writes happen atomically.
Using `std::memory_order_relaxed` should not introduce any synchronization
overhead, it should only guarantee that the operation itself is atomic.
Secondly, inline `LogCategory::setSeverity()`, as it is merely an
assignment, so going through a DSO call is a big pessimization.
`LogCategory` is not part of the public API, so this change has
no external effects.
Thirdly, assert that the atomic variable is lock free so as to ensure
it won't silently fall back to libatomic (or similar) on any platform.
If this assertion fails, this needs to be revisited.

inputBufferReady ready signal in the simple pipeline is handled in the
pipeline handler thread. outputBufferReady and ispStatsReady signals
should be handled there too.
Rather than relying on the user of the SoftwareIsp instance, let
SoftwareIsp inherits Object. SoftwareIsp serves as a signal proxy, the
signals above are emitted from signal handlers. This means that if
SoftwareIsp inherits Object then the slots are invoked in SoftwareIsp
thread. Which is the camera manager thread because the SoftwareIsp

__nodiscard was introduced for compatibility with C++14.
In C++17, there is an official attribute: [[nodiscard]].
Moreover, some libc implementations (like bionic) already define the
__nodiscard macro [1].
Since:
- libcamera builds with cpp_std=c++17
- [[nodiscard]] is already used in the android HAL (exif)
We should replace all usage __nodiscard of by [[nodiscard]] for
consistency.
Do the replacement and remove the no longer used compiler.h.

Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The Matrix constructor that takes a std::vector is meant and only used
to initialize a Matrix from an initializer list. Using a std::vector is
problematic for two reasons. First, it requires constructing a vector,
copying the data from the initializer list, which is an expensive
operation. Then, the vector size can't be verified at compile time,
making the constructor unsafe.
The first issue could be solved by replacing the vector with a
std::initializer_list or a Span. The second issue would require checking
the initializer list size with a static assertion, or restricting usage
of the constructor to fixed-extent spans. Unfortunately, even if the
size of initializer lists is always known at compile time, the
std::initializer_list::size() function is a compile-time constant only
for constant initializer lists. Using a span would work better, but
construction of a fixed extent span from an initializer list must be
explicit, making the API cumbersome.
We can solve all those issues by passing an std::array to the
constructor. Construction of an array from an initializer list can be
implicit and doesn't involve a copy, and the array size is a template
parameter and therefore guaranteed to be a compile-time constant.

Add properties covering the sensor control application delays to both
the static CameraSensorProperties definitions. The values used are
taken from Raspberry Pi's CamHelper class definitions. Where no more
specific values are known the delay struct is defined as empty and
defaults supplied through the getter function.

The terms "shutter" and "shutter speed" are used through libcamera to
mean "exposure time". This is confusing, both due to "speed" being used
as "time" while it should be the inverse (i.e. a maximum speed should
correspond to the minimum time), and due to "shutter speed" and
"exposure time" being used in different places with the same meaning.
To improve clarity of the code base and the documentation, use "exposure
time" consistently to replace "shutter speed".
This rename highlighted another vocabulary issue in libcamera. The
ExposureModeHelper::splitExposure() function used to document that it
splits "exposure time into shutter time and gain". It has been reworded
to "split exposure into exposure time and gain". That is not entirely
satisfactory, as "exposure" has a defined meaning in photography (see
https://en.wikipedia.org/wiki/Exposure_(photography)) that is not
expressed as a duration. This issue if left to be addressed separately.
