Subject: Infrastructure for deducing Param types from context, in the same way
 that the types of untyped string-literal constants are deduced (ie, when
 coerce_type is applied to 'em, that's what the type must be). Remove the
 ancient hack of storing the input Param-types array as a global variable, and
 put the info into ParseState instead.  This touches a lot of files because of
 adjustment of routine parameter lists, but it's really not a large patch. 
 Note: PREPARE statement still insists on exact specification of parameter
 types, but that could easily be relaxed now, if we wanted to do so.
