[sslh] sslh-v1.21 released

[Yves Rutschle]

Hello all,

sslh v1.21 is now available. Here's the ChangeLog:

	Added TCP_FASTOPEN support for client sockets (if
	tfo_ok is specified in their configuration) and for
	listenint socket, if all client protocols support it.
	(Craig Andrews)

	Added 'minlength' option to skip a probe if less
	than that many bytes have been received (mostly for
	regex)

	Moved configuration and command-line management to
	use conf2struct. Hopefully this should be transparent
	to users.

	Update Let's Encrypt entry in example.cfg for tls-alpn-01
	challenges; tls-sni-* challenges are now deprecated.

	Log to syslog even if in foreground (for people who
	use fail2ban)


Enjoy!
Cheers,
Y.
