Fix a passel of problems with incorrect calls to typinput and typoutput

functions, which would lead to trouble with datatypes that paid attention
to the typelem or typmod parameters to these functions.  In particular,
incorrect code in pg_aggregate.c explains the platform-specific failures
that have been reported in NUMERIC avg().
