The Raspberry Pi IPA module depends on boost only to parse the JSON
tuning data files. As libcamera depends on libyaml, use the YamlParser
class to parse those files and drop the dependency on boost.

When encountering errors, the Algorithm::read() function either uses
LOG(Fatal) or throws exceptions from the boost property_tree functions.
To prepare for replacing boost JSON parse with the YamlParser class,
give the Algorithm::read() function the ability to return an error code,
and propagate it all the way to the IPA module init() function.
All algorithm classes return a hardcoded 0 value for now, subsequent
commits will change that.

The std::map container used to store dictionary items in YamlObject
doesn't preserve the YAML data order, as maps are ordered by key, not by
insertion order. While this is compliant with the YAML specification
which doesn't guarantee ordering of mappings, the Raspberry Pi IPA
relies on elements being ordered as in the YAML data. To replace the
dependency on boost with the YamlParser class, we thus need to guarantee
that the order is preserved.
Preserve the order by storing items in list_ unconditionally. Turn the
list_ vector from storing YamlObject unique pointers to storing
key-value pairs, with the key being absent when the object is a list,
not a dictionary.
The YamlObject implementation is updated to preserve the existing API,
with the only difference being that YamlObject::memberNames() now
returns member names in the same order as in the YAML file.
The ordering is an implementation detail, so changing it doesn't violate
the YAML specification. The documentation is not updated to reflect
this, as we don't want any new user to rely on a particular ordering.
This commit could be reverted if desired when the Raspberry Pi IPA
updates to a new tuning data format and drops support for the old
format.

The YamlObject::get() function takes a default value and an optional
bool ok flag to handle parsing errors. This ad-hoc mechanism complicates
error handling in callers.
A better API is possible by dropping the default value and ok flag and
returning an std::optional. Not only does it simplify the calls, it also
lets callers handle errors through the standard std::optional class
instead of the current ad-hoc mechanism.
Provide a get() wrapper around std::optional::value_or() to further
simplify callers that don't need any specific error handling.

The logic used to match asynchronous image and embedded buffers was being overly
aggressive by possibly allowing an unmatched image buffer to be sent to the IPA
if the matching embedded buffer had not yet been dequeued. This condition only
occurs when the system is heavily loaded and dropping frames.
Fix this by holding image buffer in the queue during these conditions until the
next embedded buffer dequeue event.

Previously, ControlList::get<T>() would use default constructed objects to
indicate that a ControlList does not have the requested Control. This has
several disadvantages: 1) It requires types to be default constructible,
2) it does not differentiate between a default constructed object and an
object that happens to have the same state as a default constructed object.
std::optional<T> additionally stores the information if the object is valid
or not, and therefore is more expressive than a default constructed object.

Support the X variants of the RGB pixel formats alongside the

The QImage::Format_RGB32 and QImage::Format_RGBX8888 formats only
specify that the alpha component must be 0xff. While the Qt
documentation doesn't guarantee that the alpha value will be ignored by
consumers, this seems to be the implemented behaviour, at least when
rendering with QPainter::drawImage().

The task run function races with two other threads that want to resume
the task: the requestCompleted() handler and the buffer-notify signal
handler. If the former queues completed requests or the latter queues
back buffers to the pool, and then resume the task, after the task run
handler checks the queues but before it attemps to pause the task, then
the task may be paused without noticing that more work is available.
The most immediate way to fix this is to take the stream_lock in the
requestCompleted() and buffer-notify signal handlers, or cover the whole
task run handler with the GstLibcameraSrcState lock. This could cause
long delays in the requestCompleted() handler, so that's not a good
option.
Instead, pause the task unconditionally at the beginning of its run
function, and track while processing buffers and requests if the task
needs to be resumed. It may also get resumed externally by the
buffer-notify signal handler or the request completion handler, which
are guaranteed not to race due to the lock taken by the gst_task_pause()
and gst_task_resume() functions.
