In make-dissector-reg.py, throw an error if we don't have enough files
to process, or if we don't generate enough registrations. "Enough"
is arbitrarily set to 100.
This should de-purple the buildbot. (I'm sure there's a "smoke on the
water" joke in there somewhere.)

Python versions, as it no longer makes only "register.c", it can also
make a "plugin.c" file for a plugin.
When making "plugin.c", there's no need to include "register.h", as it's
not defining any functions declared there.
