Support TLSv1.2+

Browse Source 
The patched sources of uw-imap 2007f support building against
OpenSSL 1.1.0 or later.

However, TLSv1_client_method() and TLSv1_server_method()
restricts uw-imap to TLSv1.0.

These APIs, along with explicitly versioned APIs like
TLSv1_1_*_method() and TLSv1_2_*_method() are deprecated
in OpenSSL 1.1.0 or later. The replacements are unversioned
API functions: TLS_client_method() and TLS_server_method()
which support TLS version autonegotiation.

This allows the PHP IMAP extension to work with IMAP servers
that enforce TLSv1.2 or higher.
