In the event that we can leave prompting to a later patch, here are the v12
highlights:
- created conditional.h and conditional.c which contain the functions with
stack-ish push/pop/peek/poke names
- now all non-test, non-doc changes are in src/bin/psql
- moved conditional stack out of scan_state, stack state maintained by
mainloop.c/startup.c, passed to HandleSlashCommands
- documentation encourages the user to employ ON_ERROR_STOP when using
conditionals
