psql code cleanup:

Browse Source 
- 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
