[libcamera-devel] [PATCH 01/15] libcamera: control_ids: Add 'internal' argument

[Jacopo Mondi]

Add to the gen-controls.py script an optional argument '--internal'
that allows to specify if the generated file targets public or internal
controls.

Add two new tags to the .cpp.in and .h.in templates to specify the
correct inclusion path and the correct namespace.

Internal controls will be introduced in the next patch.
