* Add mkdtemp, TAILQ_*, and statfs. * Install a nbconfig.h file containing the discovered system information and include it directly in nbcompat.h. Make all files use nbconfig.h instead of config.h. Ensure that all installed headers don't include any local header files. This makes libnbcompat more self-contained. * Consistently use "#if HAVE_HEADER_H" instead of "#ifdef HAVE_HEADER_H" since sometimes people put -DHAVE_HEADER_H=0 on their command lines.
