Today, any source file or header file that wants to use the
tri_mode_restriction type needs to include db/config.hh, which is a
large and frequently-changing header file. In this patch we split this
type into a separate header file, db/tri_mode_restriction.hh, and avoid
a few unnecessary inclusions of db/config.hh. However, a few source
files now need to explicitly include db/config.hh, after its
transitive inclusion is gone.
Note that the overwhelmingly common inclusion of db/config.hh continues
to be a problem after this patch - 128 source files include it directly.
So this patch is just the first step in long journey.
