Import NetBSD system call regression tests. They were written with

ATF (Automated Testing Framework), so we use a small wrapper to map 
it to our bsd.regress.mk framework.  Only half of the 80 NetBSD
tests have been taken, the others need more work to adapt.  Of them 
34 syscall tests pass.
Moritz Buhl ported the tests to OpenBSD.

+Regression tests for system calls ported from NetBSD.
+
+Reimplement ATF with many hacks to adjust the tests as little as possible.
+
+Tests passing without source file adjustments:
+t_access        t_getpid        t_kill          t_msgsnd        t_sigaction
+t_bind          t_link          t_msync         t_socketpair    t_getgroups
+t_getsid        t_listen        t_pipe          t_truncate      t_getitimer
+t_getsockname   t_mkdir         t_sendrecv      t_umask         t_getlogin
+t_gettimeofday  t_msgctl        t_setuid        t_write
+
+Tests passing after adjustments:
+t_chroot        - fchroot is not implemented
+t_clock_gettime - requires sysctlbyname
+t_dup           - OpenBSD dup3 is similar to Linux dup3
+t_fsync         - replace mkstemp
+t_getrusage     - no expected fail, PR kern/30115 is NetBSD, work more
+t_mknod         - remove tests for unsupported file types
+t_msgget        - remove msgget_limit test
+t_poll          - remove pollts_* tests
+t_revoke        - remove basic tests, revoke only on ttys supported
+t_select        - remove sigset_t struct as it is int on OpenBSD
+
+Failing tests:
+t_mkfifo        - every test case fails now
+t_mlock         - wrong errno, succeeds where not expected, POSIX imprecise
+t_mmap          - ENOTBLK on test NetBSD is skipping, remove mmap_va0 test
+t_msgrcv        - msgrcv(id, &r, 3 - 1, 0x41, 004000) != -1
+t_pipe2         - closefrom(4) == -1, remove F_GETNOSIGPIPE and nosigpipe test
+t_ptrace        - ptrace(0, 0, ((void *)0), 0) != -1
+t_stat          - invalid GID with doas
+t_syscall       - SIGSEGV
+t_unlink        - wrong errno according to POSIX
+
