r273482:

  The NetBSD libc tests use several definitions/macros that aren't available in
  FreeBSD

  Add the missing compat definitions/macros to lib/libnetbsd so the testcases
  can be compiled with libnetbsd without having to invent ad hoc #define's, or
  having to convert things over to FreeBSD idioms

MFC r274784:

Fix smbfs to not zero out statfs f_flags field. Previously, this
made getmntinfo() return empty flags for smbfs filesystems when
called with MNT_WAIT. It's not visible with mount(8), since it uses
MNT_NOWAIT, but broke autounmount(8) operation.
