Make external/firebird work with C++14 sized deallocation

...where firebird's replacements of global new/delete would still be called for
"new" but not for "delete".  Lets hope that always adding the C++14 size_t
overloads of operator delete is harmless in all relevant pre-C++14 environments,
and only causes harmless warnings like -Wimplicit-exception-spec-mismatch in all
relevant C++14 environments.

(But why does a /library/ replace global new/delete in the first place?)
