Update to the default TLS configuration settings. Resolves several SPF  
lookup issues. Fixes build issues on some platforms.

Changes:

• Updated OpenSSL TLS_PROTOCOL settings. Changed the default setting value  
to support TLS 1, and higher, only.

• the OpenSSL version of the mkdhparams script's default changed to a 2048  
bit DH parameter key. The RPM package creates the initial DH parameter key  
when the package gets built.

• imap: watchdog timer that kills the IMAP server when the FAM library hangs  
at initialization will try to log a message to standard error, before dying.

• Removed obsolete code that adds a DH parameter section to the default self- 
signed cert.

• Fixes a bug in SPF lookup on IPv6-capable servers.

• SPF lookups can handle multiple text strings in an SPF DNS record.

• Enable EC ciphers when using OpenSSL.

• Other minor build script fixes.
