TLS (aka SSL) Channel - can be layered on any bi-directional Tcl_Channel.

Both client and server-side sockets are possible, and this code should work
on any platform as it uses a generic mechanism for layering on SSL and Tcl.

Full filevent sematics should also be intact - see tests directory for
blocking and non-blocking examples.

The current release is TLS 1.6, with binaries built against OpenSSL 0.9.8g.
For best security and function, always compile from source with the latest
official release of OpenSSL (

TLS 1.7 and newer require Tcl 8.4.0+, older versions may be used if older
versions of Tcl need to be used.
