The CameraSensor class is noisy enough in reporting the missing
sensor driver features.
Demote an error message about defaulting the active sensor area when
retrieving the camera sensor info to a warning.

Replace the __FILE__ and __LINE__ values passed to the _log() function
with default parameters, taking their values from the __builtin_FILE()
and __builtin_LINE() functions. This moves handling of the file and line
from the preprocessor to the compiler, which is generally preferred as
it increases type safety.

The _log() functions, as well as the LogMessage constructor, exist in
two versions, one that takes a log category, and one that doesn't. The
latter uses the default log category. This can be simplified by passing
a LogCategory pointer to _log(), which can then be null for the default
category, and moving the retrieval of the default log category from the
LogMessage constructor to the _log() function.

Previously when a frame got cancelled, the frameInfo flags
metadataProcessed and paramDequeued wouldn't get set, meaning that the
request wasn't able to be completed and cancelled.
Make sure that these flags are set when the frame gets cancelled so that
the request can be cancelled.
This issue happened while running lc-compliance.

Add a compliance tool to ease testing of cameras. In contrast to the
unit-tests under test/ that aims to test the internal components of
libcamera the compliance tool aims to test application use-cases and to
some extent the public API.
This change adds the boilerplate code of a simple framework for the
creation of tests. The tests aim both to demonstrate the tool and to
catch real problems. The tests added are:
- Test that if one queues exactly N requests to a camera exactly N
requests are eventually completed.
- Test that a configured camera can be started and stopped multiple
times in an attempt to exercise cleanup code paths otherwise not
often tested with 'cam' for example.

path issues, build.ninja can't be located by ninja. meson generates
ninja files fine, but then when you run ninja, it is unable to find
meson's build.ninja python module due to path issues.
It gives the following error on ninja -C build install:
ninja: Entering directory `build'
ninja: error: loading 'build.ninja': No such file or directory
After uninstalling meson using pip3 and installing it again using pip
without --user argument solved the issue.

cros::CameraBufferManager::Register() fails if a buffer handle
is invalid. We should mark CameraBuffer as invalid on the failure
of Register().
While the cros::CameraBufferManager Unlock() and Deregister() functions
should be able to handle buffers that haven't been locked and
registered, this isn't an API guarantee, and errors will be logged.
Avoid this by skipping unlocking and unregistration of buffers that
haven't been locked or registered.

When the camera is being stop()ped, active requests will complete. These
may trigger an application to re-queue those requests to the camera but
that is not permitted, and is an error in the application.
Extend the camera state to include a stopping state which is entered as
soon as a call to stop() is made. At this point, any request queued will
be rejected with a warning, while any pending requests are either
successfully completed or cancelled.
When the pipeline handler has finished stopping, the camera state will
transition to the CameraConfigured state where it can begin to accept
requests again, and be restarted.

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 &)
