This patch moves the formerly internal classes of the report-ROM service
to the public location os/include/report_rom/ so that they can be reused
by other components such as the upcoming clipboard.
If a requested report already exists the request is denied with
Invalid_args.
Further, I dusted the report_rom test and added it to the
autopilot list.
This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
Issue #1082
