pgsql: Rename strtoi() to strtoint().

Rename strtoi() to strtoint().

NetBSD has seen fit to invent a libc function named strtoi(), which
conflicts with the long-established static functions of the same name in
datetime.c and ecpg's interval.c. While muttering darkly about intrusions
on application namespace, we'll rename our functions to avoid the conflict.

Back-patch to all supported branches, since this would affect attempts
to build any of them on recent NetBSD.
