Refactor tls code to support ucspi-tls

2020-11-20T23:24:29Z

That includes: - new architecture: the tls binary is now a child of the app instead of the other way around - the sbearssl_run engine now takes a post-handshake callback. This allows s6-tlsc and s6-tlsd to only exec into the app when the handshake succeeds (which was already the case with libressl). - new binaries s6-tlsc-io and s6-tlsd-io encapsulate the crypto code; they init and run the engine, connecting to 4 already open fds (stdin/stdout = network, argv[1] and argv[2] = local) - s6-tlsc is now a simple wrapper around s6-tlsc-io - s6-tlsd is now a simple wrapper around s6-tlsd-io - new binary: s6-ucspitlsd, which is also a wrapper around s6-tlsd-io, but differently: the parent execs the app which should be ucspi-tls-aware, the child waits for a command from the parent and execs into s6-tlsd-io if it receives it.
