subversion: fix CVE-2017-9800
A maliciously constructed svn+ssh:// URL would cause Subversion clients
before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3
to run an arbitrary shell command. Such a URL could be generated by a
malicious server, by a malicious user committing to a honest server(to
attack another user of that server's repositories), or by a proxy
server.
The vulnerability affects all clients, including those that use
file://, http://, and plain (untunneled) svn://.
