Provide a sequence number on Requests which are added by the pipeline
handler.
Each pipeline handler keeps a requestSequence per CameraData and
increments everytime a request is queued on that camera.
The sequence number is associated with the Request and can be utilised
for assisting with debugging, and printing the queueing sequence of in
flight requests.

The FrameBuffer class is only friends with Request so that the request
can be associated with the buffers.
FrameBuffer already has a helper to setRequest(), so let's use that
directly instead.

Asynchronous tasks can only be submitted while the IPA is running.
Further more, the shutdown sequence can not be tracked with a simple
running flag. We can also be in the state 'Stopping' where we have not
yet completed all events, but we must not commence anything new.
Refactor the running_ boolean into a stateful enum to track this.

A range-based for loop whose range expression is an array of char
pointers and range variable declaration is a const reference to a
std::string creates a temporary string from the char pointer and binds
the range variable reference to it. This creates a const reference to a
temporary, which is valid in C++, and extends the lifetime of the
temporary to the lifetime of the reference.
However, lifetime extension in range-based for loops is considered as a
sign of a potential issue, as a temporary is created for every
iteration, which can be costly, and the usage of a reference in the
range declaration doesn't make it obvious that the code isn't simply
binding a reference to an existing object. gcc 11, with the
-Wrange-loop-construct option, flags this:
uvcvideo.cpp:432:33: error: loop variable 'name' of type 'const string&' {aka 'const std::__cxx11::basic_string<cha
r>&'} binds to a temporary constructed from type 'const char* const' [-Werror=range-loop-construct]
| 432 | for (const std::string &name : { "idVendor", "idProduct" }) {
| | ^~~~
To please the compiler, make the range variable a const char *. This may
bring a tiny performance improvement, as the name is only used once, in
a location where the compiler can use
operator+(const std::string &, const char *)
instead of
operator+(const std::string &, const std::string &)

CameraDevice::camera() originally returns shared_ptr. It is
mandatory to make a copy by calling camera() in this way. There
is no need of copying if a caller needs the reference of the
camera like const shared_ptr<Camera> &cam = camera(). That is, it
is a caller that copying is required. This changes the return
type of camera() to const shared_ptr&, so that we are able to
reduce one redundant copy in the above case.

The V4l2 buffer cache allows us to map incoming buffers to an instance
of the V4L2 buffer required to actually queue.
If the cache_ is not available, then the buffers required to allow
queuing to a device have been released, and this indicates an issue at
the pipeline handler.
This could be a common mistake, as it could happen if a pipeline handler
always requeues buffers to the device after they complete, without
checking if they are cancelled.
Catch any invalid queueing of buffers to the V4L2 video device when
resources have been released by adding a Fatal log message to highlight
the error during development.

When the imguOutputBufferReady() detects a cancelled frame, it is
reporting that the metadata has been processed in order to be able to
complete the cancelled request.
This causes the FrameInfo to be completed and deleted early, but then an
active buffer on the IMGU can complete and be unable to find the
FrameInfo for it to complete correctly.
Do not mark metadataProcessed early on the event that a single buffer is
detected as cancelled. The stopping of the V4L2 devices will ensure
that all queued buffers are returned to us and we can follow the normal
and expected shutdown sequence.
