remove andmap from public API (we still have and-map)

* module/ice-9/boot-9.scm (and-map, or-map): Move these definitions up so
  psyntax can use them.
  (andmap): Remove, yay.

* module/ice-9/psyntax.scm: Remove notes about andmap, and just use
  Guile's and-map -- except in cases that need the multiple list support,
  in which case we have a private and-map*.

* module/ice-9/psyntax-pp.scm: Regenerated.
