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 (http://www.openssl.org/).

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

TclTLS requires OpenSSL or LibreSSL in order to be compiled and function.
