MFC r313679:

Use SRCTOP/OBJTOP relative paths where possible; use :H manipulation in lieu
of ../ elsewhere

This simplifies pathing in make/displayed output

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.

Relnotes: yes

r264400:

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

r265836:

Remove last two NO_MAN= in the tree. In both of these cases, MAN= is
what is needed.
