psql code cleanup:
- refactor a bunch of code to call a separate function print_msg() which checks whether "silent mode" is enabled before printing an error message. - rename "silence_mode" to "silent_mode", which IMHO makes more sense - make the error messages we emit in "waiting" mode more consistent; I believe this fixes a recent error message regression
