A module that is meant to make up the userspace experience of the driver
is no longer referred to as AIM. Instead it is denoted as a component of
the core. Further, it is understood as an integral part of the core, the
purpose of which is to meaningfully enhance the core with new features
(interface the userspace in a certain way). Therefore, this patch renames
aim with component or its abbreviation comp.
