New Revision: 1807136

URL: http://svn.apache.org/viewvc?rev=1807136&view=rev
Log:
Improve TLS handshake.

When using JSSE TLS configuration with the OpenSSL
implementation and client certificates: include
client CA subjects in the TLS handshake so that
the client can choose an appropriate client
certificate to present.

This fix needs at least version 1.2.13 of the
Tomcat Native Library to work.

We will remove catching an UnsatisfiedLinkError
after the required tcnative version was increased
from trunk and tc 8.5.

Backport of r1804903, r1804907 and r1807135
from trunk.
