Remove stringref::c_str()

The expected semantics of c_str() (a null-terminated string) cannot
be satisfied with a string reference, so remove the function entirely
to prevent people from using it in buggy ways.

Replaces c_str() with data() in places where it is presumed safe,
otherwise constructs temporary string instances. Certain callsites
have been de-stringref'd in favor of regular strings, in particular
where C APIs have been transitively called. The vast majority of
these were called with string parameters anyway, so should not
cause much extra allocation.
