Split out everything that looks like a function call from c_expr into
a separate production func_expr. This allows us to accept all these
variants in the backwards-compatible syntax for creating a functional
index; which beats documenting exactly which things work and which don't.

A few minor list-related cleanups:
(1) Replace while loop with the new forboth() construct in
parser/analyze.c

this case, and using lappend() leads to cleaner code.
