[Asterisk-code-review] Check for OpenSSL defines before trying to use them. (asterisk[13])

[Mark Michelson]

Hello Richard Mudgett, Anonymous Coward #1000019,

I'd like you to reexamine a change.  Please visit

    https://gerrit.asterisk.org/2198

to look at the new patch set (#2).

Change subject: Check for OpenSSL defines before trying to use them.
......................................................................

Check for OpenSSL defines before trying to use them.

The SSL_OP_NO_TLSv1_1 and SSL_OP_NO_TLSv1_2 defines did not exist prior
to OpenSSL version 1.0.1. A recent commit attempts to, by default, set
these options, which can cause problems on systems with older OpenSSL
installations.

This commit adds a configure script check for those defines and will not
attempt to make use of those if they do not exist. We will print a
warning urging the user to upgrade their OpenSSL installation if those
defines are not present.
