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 RGB to YCbCr conversion matrix mentioned in a comment, coming from
the hardware documentation, does not match any of the canonical matrices
specified by any standard. While researching where the values came from,
it became apparent they are likely Bt.601 limited range coefficients
rounded to 6 bits of decimal precision. Record this in comments.

The x(), y() and z() functions of the Vector class are convenience
accessors for the first, second and third element of the vector
respectively, meant to improve readability of class users when a vector
represents coordinates in 1D, 2D or 3D space. Those accessors are
limited to immutable access to the vector elements, as they return a
copy. Extend the API with mutable accessors.
The immutable accessors are modified to return a reference to the vector
elements instead of a copy for consistency. As they are inline
functions, this should make no difference in terms of performance as the
compiler can perform the same optimizations in their case.
While at it, reorder functions to declare operators before other member
functions, to be consistent with the usual coding style.

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.

Before commit eeaa7de21b8c ("libcamera: pipeline: Add test pattern for
VirtualPipelineHandler") the libyuv dependency was only needed for the
Android adaptation layer. As libyuv isn't packaged by most distribution,
meson fell back to using a meson wrap if the Android adaptation layer
was enabled and the library wasn't found.
With commit eeaa7de21b8c, libyuv is also used by the virtual pipeline
handler, and the meson wrap fallback handling got centralized and became
unconditional, so the wrap is downloaded even if the components
depending on libyuv are all disabled. This causes unnecessary downloads
at setup time, which can be problematic on build systems without an
internet connection.
Fix this by making the wrap fallback conditional on the components that
use libyuv.

Some IPA modules, like the RkISP1 one, call FCQueue::get(0) at
IPA::start() time, before any frame context has been allocated with
FCQueue::alloc() called at queueRequest() time.
The FCQueue implementation aims to detect when a FrameContext is get()
before it is alloc()-ated, Warns about it, and initializes the
FrameContext before returning it.
In case of frame#0, a get() preceding an alloc() call is not detected
as the "frame == frameContext.frame" test returns success, as
FrameContexts are zeroed by default.
As a result, the first returned FrameContext is not initialized.
Explicitly test for frame#0 to make sure the FrameContext is initialized
if get(0) is called before alloc(0). To avoid re-initializing a frame
context, in case alloc() has been called correctly before get(),
introduce an "initialised" state variable that tracks the FrameContext
initialisation state.

The Fatal check of having at least one MediaDevice was to prevent
pipeline handler implementations searching and owning media devices with
custom conventions, instead of using the base function

Now that the assumption will be broken by the virtual pipeline handler

std::from_chars(), introduced in C++17, is a fast, locale-independent
string-to-arithmetic conversion function. The C++ standard library
provides overloads for all integer types, making it a prime candidate to
replace the manual handling of integer sizes in the YamlParser string to
integer conversion.
Compared to std::strtol(), std::from_chars() doesn't recognize the '0x'
prefix or '+' prefix, and doesn't ignore leading white space. As the
YamlParser doesn't require those features, std::from_chars() can be used
safely, reducing the amount of code.
C++17 also requires the standard C++ library to provide overloads for
floating-point types, but libc++ does not implement those. The float and
bool implementations of YamlParser::Getter::get() are therefore kept
as-is.

Debug metadata often occurs in places where the metadata control list is
not available e.g. in queueRequest() or processStatsBuffer() or even in
a class far away from the metadata handling code. It is therefore
difficult to add debug metadata without adding lots of boilerplate

to the metadata control list when it becomes available. To solve the
issue of code that is far away from the metadata context, add a chaining

If the CameraManager fails to initialise at startup during

thread for operations, but the thread will immediately close without
executing any cleanup.
This can leave instantiated objects such as the EventNotifier registered
by the udev enumerator constructed in a thread which no longer exists.
The destructor of those objects can then fire an assertion that they are
being executed from an incorrect thread while performing their cleanup.
Ensure that the failure path does not result in reporting thread

The names used by the IPA interface and the names used for buffer
completions handlers in libcamera clash in the use of the term "buffer".
For example video device buffer completion handler is called
"bufferReady" and the IPA event to ask the IPA to compute parameters are
called "fillParamsBuffers". This makes it hard to recognize which
function handles video device completion signals and which ones handle
the IPA interface events.
Rationalize the naming scheme in the IPA interface function and events
and the signal handlers in the pipelines, according to the
following table. Remove the name "buffer" from the IPA interface events
and events handler and reserve it for the buffer completion handlers.
Rename the IPA interface events and function to use the 'params' and
'stats' names as well.
IPA Interface:
- fillParamsBuffer -> computeParams [FUNCTION]
- processStatsBuffer -> processStats [FUNCTION]
- paramFilled -> paramsComputed [EVENT]
Pipeline handler:
- bufferReady -> videoBufferReady [BUFFER HANDLER]
- paramReady -> paramBufferReady [BUFFER HANDLER]
- statReady -> statBufferReady [BUFFER HANDLER]
- paramFilled -> paramsComputed [IPA EVENT HANDLER]
Cosmetic change only, no functional changes intended.

PipelineHandler::stop() calls stopDevice() method to perform pipeline
specific cleanup and then completes waiting requests. If any queued
requests remain, an assertion error is raised.
Software ISP stores request buffers in
SimpleCameraData::conversionQueue_ and queues them as V4L2 signals
bufferReady. stopDevice() cleanup forgets to clean up the buffers and
their requests from conversionQueue_, possibly resulting in the
assertion error. This patch fixes the omission.
The problem wasn't very visible when
SimplePipelineHandler::kNumInternalBuffers (the number of buffers
allocated in V4L2) was equal to the number of buffers exported from
software ISP. But when the number of the exported buffers was increased
by one in commit abe2ec64f9e4e97bbdfe3a50372611bd7b5315c2, the assertion
error started pop up in some environments. Increasing the number of the
buffers much more, e.g. to 9, makes the problem very reproducible.
Each pipeline uses its own mechanism to track the requests to clean up
and it can't be excluded that similar omissions are present in other
places. But there is no obvious way to make a common cleanup for all
the pipelines (except for doing it instead of raising the assertion
error, which is probably undesirable, in order not to hide incomplete
pipeline specific cleanups).
