GSoC Upgrade firebird to 3.0

Embedded firebird is now version 3.0.

Supports MSVC 14.0.

Instead of fbembed, there are now two libraries: fbclient and
Engine12. fbclient is linked as fbembed before, Engine12 is loaded
at runtime from fbclient.

fb now needs system libtommath, which is supplied
as a new ExternalProject of LO.
