* configure.in: Check for access, ftime, getcwd, srand48, srand, srandom, stat,
strchr, strerror, strstr, timezone, umask, waitpid, sem_init, sem_trywait,
daemon, alloca.h, dlfcn.h, limits.h, pthread.h, semaphore.h, krb_db.h, kdc.h,
sockaddr.sa_len, sockaddr_in.sin_len, stat.st_mtimensec,
stat.st_mtimespec.tv_nsec, and stat.st_mtim.tv_nsec.  Invoke
KRB5_AC_REGEX_FUNCS, AC_TYPE_OFF_T, CHECK_WAIT_TYPE, CHECK_SIGPROCMASK,
AC_TYPE_GETGROUPS, CHECK_SETJMP, and DECLARE_SYS_ERRLIST.  Add checks for
perror declaration, strptime prototype, setrpcent and endrpcent return types
from configure.in scripts in subdirectories.

With this patch, nearly every -D option used to compile a file that we care
about for KfM should now be duplicated in include/autoconf.h.  There are still
other -D options not represented here (e.g., in appl/, util/pty, and the python
sample plugin).
