Use printf's %m format instead of strerror(errno) in more places
Most callers of strerror() are removed from the backend code. The
remaining callers require special handling with a saved errno from a
previous system call. The frontend code still needs strerror() where
error states need to be handled outside of fprintf.
Note that pg_regress is not changed to use %m as the TAP output may
clobber errno, since those functions call fprintf() and friends before
evaluating the format string.
Support for %m in src/port/snprintf.c has been added in d6c55de1f99a,
hence all the stable branches currently supported include it.
