Move compiler.h to commonlib

Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.

Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.
