Recently #include directives for autoconf's config.h file were added in

Recently #include directives for autoconf's config.h file were added in
utils/mount/error.c and utils/mount/mount.c, but appropriate HAVE_CONFIG_H
checks were not added at the same time.

In addition, several other .c files under utils/mount reference
autoconf-generated HAVE_ macros, but don't appear to include config.h

Also, Heinz-Ado Arnolds <arnolds@MPA-Garching.MPG.DE> reports that this
patch is needed to ensure START_STATD is properly defined in
utils/mount/network.c.  Otherwise start_statd() is always a no-op, even if
the configure script defines an appropriate statd start-up script.
