dns/nsd: update 4.3.0 -> 4.3.1

BUG FIXES:
- Fix #70: error: 'fd_set' undeclared.
- Fix #71: error: 'for' loop initial declaration used outside C99
  mode.
- Fix to move declarations out of for loops in event test too.
- Fix #76: cpuid typedef for Hurd, DragonflyBSD compile.
- Fix #75: configure test for sched_setaffinity, and use
  cpuset_setaffinity otherwise.  Also test for presence of sysconf.
- Fix #74: GNU Hurd fix cast from pointer to integer of different size.
- Fix for #74, #75: cpuset test for header contents and provide code.
- Fix #78: Fix SO_SETFIB error on FreeBSD.
- Merge PR #83 from noloader: Fix GNU HURD sched_setaffinity compile.
- Fix #80: NetBSD and implicit declaration of reallocarray.
- Fix unknown u_long in util.c for Issue #80 .
- Merge PR #86 from noloader: Use precious variables for GREP, EGREP,
  SED, AWK, LEX and YACC.
- For PR #86: Fix that programs loaded after CFLAGS and stuff is
  set, specifically the compiler, so that it can work if it needs
  special flags from that.  Fix that lex only needs to support -i
  if actually defined, otherwise the output included in the source
  tarball can be used.
- Merge PR #90 by phicoh: O_CLOEXEC should be FD_CLOEXEC.
- Merge PR #92 by tonysgi: Fix typo.
- Merge PR #91 by gearnode: nsd-control-setup recreate certificates.
  The '-r' option recreates certificates.  Without it it creates them
  if they do not exist, and does not modify them otherwise.
