MFC r275385 (by bapt):
  Sync the svn template with the one from ports

MFC r289180 (by peter):
  Update from svn-1.8.14 to 1.9.2.

  Formal release notes are available:
    https://subversion.apache.org/docs/release-notes/1.9.html

  Of particular note, the client checkout format has *not* changed so
  upgrades should *not* be required.

  When reading a repository (file:// or running as a local server), an
  improved fsfs version 7 is available with significant performance
  improvements.  An optional upgrade is possible to use the new features.
  Without the upgrade, this is fully read/write compatible with the
  version 6 fsfs as in svn-1.8.

MFC r298845:
  Update from subversion 1.9.2 to 1.9.4.

  This contains only bug fixes, no new features.  The repository format is
  also unchanged from 1.9.2.  Full list of changes between 1.9.4 and
  earlier versions:

    https://svn.apache.org/repos/asf/subversion/tags/1.9.4/CHANGES

  Note that the two security issues fixed in 1.9.4 (CVE-2016-2167 and
  CVE-2016-2168) do not affect the version of Subversion in the FreeBSD
  base system, since neither SASL nor Apache modules are enabled.

MFC r298996:
  Re-sync the FreeBSD-specific Subversion template with the one from
  ports.
