        Merge remote-tracking branch 'upstream/master' into poudriere

          While testing building the FreeNAS ports tree with poudriere,
          poudriere encountered problems building net/samba41, due
          to dependencies introduced by the FAM port option.
          It turns out that the FreeNAS ports tree was missing a lot of
          infrastructure in ports/Mk/* related to this option.
          Figuring out which fixes to cherry-pick into our tree was too hard.

          Instead, I merged the master branch of the FreeBSD ports tree
          into the FreeNAS ports tree, on a separate poudriere branch.

          I left the net/rsync port at the 3.0.9 version in FreeNAS,
          instead of updating it to 3.1.0, because the FreeNAS-specific
          patches to net/rsync do not apply to 3.1.0 and it will be a little
          bit of work to forward-port those patches.
