Currently the function `createPipelineHandlers` connects itself to the
`devicesAdded` signal at the end of each call. As the Signal object
supports multiple non-unique listeners connected to it, the former
function would be called exponentially often with each new emitted event
on `devicesAdded` (i.e. with udev plugging in a new camera)
Fix it by connecting the createPipelineHandlers() slot to `devicesAdded`
signal in CameraManager::Private::init() instead. This will prevent the
slot getting connected multiple times to the `devicesAdded` signal.

Currently it is not possible to display debug output from an isolated IPA
module. The standard descriptors are all closed and any specified log
file is explicitly deactivated for the IPA module. Since libcamera and the
isolated IPA module are separate processes, they cannot write to the same

If syslog is specified as a log file, then this is left as it is for the

The supported pipelines are listed in three places: the
meson_options.txt file, the defined array when a user selects
-Dpipelines="all", and arrays defined when the default
-Dpipelines="auto" is selected.
This can be hard to maintain and error prone.
Rework the definition of pipeline selection to a single table which
specifies the architecture(s) that the pipeline handler supports and
iterate it to handle the special cases for 'all', 'auto' and 'test'.
The current behaviour such that 'all' takes precedence over 'auto' is
maintained, and 'test' is now extended such that additional test
pipeline handlers can easily be introduced.
The existing implementation defines the i.MX8-ISI and RKISP1 pipeline
handlers as only supported by 'aarch64'. This conversion changes the
behaviour such that those pipeline handlers are now supported on both
'arm' and 'aarch64' as each of those platforms could support a 32-bit
ARM build.
