Sync the EFI headers with version 1.10.14.62 of the Intel sample EFI
implementation. This re-introduces C99 style comments that previously
were replaced by original C comments.

An almost mechanical sweep to replace C++ style comments with C
style comments. This is not an attempt to conform to style(9).
Such has lower priority.

First approximation of an ia64 EFI loader. Not functional.
