Improve frontend error logging style.

Browse Source 
Get rid of the separate "FATAL" log level, as it was applied
so inconsistently as to be meaningless.  This mostly involves
s/pg_log_fatal/pg_log_error/g.

Create a macro pg_fatal() to handle the common use-case of
pg_log_error() immediately followed by exit(1).  Various
modules had already invented either this or equivalent macros;
standardize on pg_fatal() and apply it where possible.

Invent the ability to add "detail" and "hint" messages to a
frontend message, much as we have long had in the backend.

Except where rewording was needed to convert existing coding
to detail/hint style, I have (mostly) resisted the temptation
to change existing message wording.

Patch by me.  Design and patch reviewed at various stages by
Robert Haas, Kyotaro Horiguchi, Peter Eisentraut and
Daniel Gustafsson.
