r14624: - add timelimit.c

- add configure tests --with-selftest-prefix=/tmp/samba-test
  this is needed because the path name of unix socket can only be 108 chars long
- add configure test --with-smbtorture4-path=/home/foo/prefix/samba4/bin/smbtorture
  this will be used to run samba4's smbtorture inside samba3's make test later
