Ensure that when we check for existence with File() it will only return
if the path leads to a file, and not a directory.
Device nodes which could still be opened by this class are still
supported.

Directories can not be opened as a file, so the exists() check should
not return true for a path which points to a directory.
Directories are not handled by the File class.

The existing implementation of the BayerFormat class supports
converting a V4L2PixelFormat to a BayerFormat and vice-versa.
Expand the class by adding support for converting a media bus code
to a BayerFormat instance, by providing a conversion table and a
dedicated static methods.
Do not provide support for converting a BayerFormat to a media bus code
as there's no 1-to-1 mapping between the two.

Add a commit checker that ensures that all header files added to the
libcamera includes (public or internal) are accompanied by a
corresponding update of the meson.build file in the same directory.
Here's the output of the new checker when run against a commit that
forgot to update meson.build.
$ ./utils/checkstyle.py b3383da79f1d
---------------------------------------------------------------------------------
b3383da79f1d513b0d76db220a7104e1c1035e30 libcamera: buffer: Create a MappedBuffer
---------------------------------------------------------------------------------
Header include/libcamera/internal/buffer.h added without corresponding update to include/libcamera/internal/meson.build
---
1 potential issue detected, please review
In theory we could extend the checker to cover .cpp files too, but the
issue will be quite noticeable as meson won't build the file if
meson.build isn't updated. Header files are more tricky as problems
would only occur at when installing the headers (for public headers), or
would result in race conditions in the build. Both of those issues are
harder to catch.

The details namespaces in libcamera are used to hide implementation
details, and should thus be excluded from documentation generation. This
is done incorrectly by specifying the exclusion pattern "*::details::*"
which will ignore all namespaces and types in any details namespace, but
won't ignore functions. Fix it by removing the trailing "::*", causing
Doxygen to ignore the namespace itself, and thus all its contents.

Previously the CamHelper was returning the number of frames to drop
(on account of AGC/AWB converging). This wasn't really appropriate,
it's better for the algorithms to do it as they know how many frames
they might need.
The CamHelper::HideFramesStartup method should now just be returning
the number of frames to hide because they're bad/invalid in some way,
not worrying about the AGC/AWB. For many sensors, the correct value
for this is zero. But the ov5647 needs updating as it must return 2.

colour gains
When the AWB is started from "cold" with fixed colour gains, we try to
estimate the colour temperature this corresponds to (if a calibrated
CT curve was supplied). When fixed colour gains are set after the AWB
has been running, we leave the CT estimate alone, as the one we have
is probably sensible.
This estimated colour is passed out in the metadata for other
algorithms - notably ALSC - to use.

configure
The number of frames to drop (not display) is passed back now from the
start method, not configure. This means applications have a chance to
set fixed exposure/gain before starting the camera and this can affect
the frame drop count that is returned.
Note how we need to be able to tell the very first time we start the
camera from subsequent restarts, hence addition of the "firstStart_"
flag.
