Edwin Kempin d1e2c2f2c8 Fix SSL security issue in the SMTP email relay code
The hostname of the SSL socket was not verified. This made the read
from the socket insecure since without verifying the hostname it may
be vulnerable to a man-in-the-middle attack as described in [1].

This issue was reported by Sam Blackshear and Jules Villard from the
Infer static analysis team at Facebook and it was detected by running
Infer [2] on the Gerrit code base.

As described in [3] Java 7 has a mechanism to verify the identity of
the certificate directly as part of the SSLSocket/SSLEngine API, and
with this change we make use of it to verify the hostname.

I discussed this with Shawn and we decided to develop this fix in open
source since the issue is in a non-critical part of Gerrit.
