Further improve consistency of configure's program searching. Peter Eisentraut noted that commit 40b9f1921 had broken a configure behavior that some people might rely on: AC_CHECK_PROGS(FOO,...) will allow the search to be overridden by specifying a value for FOO on configure's command line or in its environment, but AC_PATH_PROGS(FOO,...) accepts such an override only if it's an absolute path. We had worked around that behavior for some, but not all, of the pre-existing uses of AC_PATH_PROGS by just skipping the macro altogether when FOO is already set. Let's standardize on that workaround for all uses of AC_PATH_PROGS, new and pre-existing, by wrapping AC_PATH_PROGS in a new macro PGAC_PATH_PROGS. While at it, fix a deficiency of the old workaround code by making sure we report the setting to configure's log.
Eventually I'd like to improve PGAC_PATH_PROGS so that it converts non-absolute override inputs to absolute form, eg "PYTHON=python3" becomes, say, PYTHON = /usr/bin/python3. But that will take some nontrivial coding so it doesn't seem like a thing to do in late beta.
