Markus Armbruster e42053d928 Break inclusion cycle: prototypes.h and commands.h included each
other.  Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special).  New header types.h to
help avoid inclusion cycles.  Sort include directives.  Remove some
superflous includes.
