Remove 'tripflag' from dive trips

Browse source 
Both dives and dive trips have the same 'tripflag' thing, but they are
used very differently.  In particular, for dive trips, the only case
that has any meaning is the TF_AUTOGEN case, so instead of having that
trip flag, replace it with a bitfield that says whether the trip was
auto-generated or not.

And make the one-bit bitfields explicitly unsigned.  Signed bitfields
are almost always a mistake, and can be confusing.

Also remove a few now stale macros that are no longer needed now that we
don't do the GList thing for dive list handling, and our autogen logic
has been simplified.
