RAS: Add CEC collector and deprecate mcelog

From: Borislav Petkov <[email protected]>

Hi,

here's the latest incarnation of the CEC collector. I think I've taken care of all review comments but feel free to correct me here. The introductory comment in cec.c should explain the whole deal - I'm referring to there so that we have that text in the actual source and not spread it around commit messages. So pls have a look there for more info.

The thing has knobs in debugfs now which can control its operation, I hope I've chosen sane default values.

x86/MCE: Rename mce_log()'s argument
x86/MCE: Rename mce_log to mce_log_buffer
