Emmanuele Bassi 02b69e4d76 Move header inclusion guard at the top 
GCC has some optimization for the inclusion guard, but they only work if
the check is the outermost one.

We're fairly inconsistent because of historical reasons, so we should
ensure that we follow the same pattern in every public header.
