external/firebird: Backport fix for CORE-5452 causing spurious SEGV
...while building LO. Patches from <https://github.com/FirebirdSQL/firebird>'s B3_0_Release branch; to apply, 0002 needed 0001 first (which looks like a reasonable thing to include in itself, anyway), plus a trivial whitespace modification, plus an additional #include for Windows.
