This is an x86-specific module and would benefit from being
closer to the arch code. Move it there. Update copyright while
at it.

Implement a new debugfs interface for RAS susbsystem.
A file named daemon_active is added there accordingly.
This file is used to track if user space daemon accesses
perf/trace interface or not. One can track which daemon
opens it via "lsof /path/to/debugfs/ras/daemon_active".

To avoid confuision and conflict of usage for RAS related trace event,
add an unified RAS trace event stub.
Start a RAS subsystem menu which will be fleshed out in time, when more
features get added to it.
