MFH (r255243): create /var/authpf with correct ownership and permissions
MFH (r255597): add unbound user to facilitate cross-building
MFH (r256097): add missing entries to ftpusers and reorder
MFC r255944 (partial):

  Use MK_SSP=no after including bsd.own.mk to disable SSP instead of user-knob
  WITH[OUT]_SSP to avoid hitting an error if user has WITH_SSP in their
  make.conf. Ports now use this knob.

    make[7]: "/usr/src/share/mk/bsd.own.mk" line 466: WITH_SSP and
    WITHOUT_SSP can't both be set.

Add padding to match the compat32 struct stat32 definition to the real
struct stat on 32bit architectures.
MFH (206038,206040): add a -k option which is passed through to finger(1).
Almost to the day three and a half years after the original MFC date...
MFC r255931:

Fix a bug in ld, where indirect symbols are not handled properly during
linking of a shared library, leading to corrupt indexes in the dynamic
symbol table.  This should fix the multimedia/ffmpegthumbnailer port.
