Use booleans, not the old empty-string-or-undefined.
This bugfix is a breaking change, but chances are it won't affect many
clients.

Allow callers to get protocol-relative URLs by passing the
PROTO_RELATIVE constant. Since most callers don't pass in $proto, this
shouldn't change very much since the default of non-expanded is
effectively the same, but expanding to a protocol-relative URL when it
is not intended should still be safe.
A few callers that explicitly specified the default in core were also
updated.

I244a66fe19c089df4bcabcf745536d99b2103bc4 splitted RevisionDelete.php in
11 files, but that removed code formatting and produced long lines.
Restored code formatting and added newline at end of files.
