Add -J and -j to the TLS tools to check for peer close_notify.

Also, and more importantly, significantly rewrite stls_run() for better full-duplex support. This implementation isn't fully tested yet. Signed-off-by: Laurent Bercot

Change -K semantics: timeout during handshake, not afterwards

2020-12-07T12:53:54Z

- the TLS tunnel itself should be transparent so it has no business shutting down the connection no matter how long the app takes - there's still an undetectable situation on some kernels where EOF doesn't get transmitted from the network, and the engine is in the handshake, and it can't do anything but wait forever. A timeout is useful here: dawg, your peer is never going to send any more data, you should just give up. - if the situation happens after the handshake, the *app* should have a timeout and die. The tunnel will follow suit. - libtls has a blocking tls_handshake() blackbox, we cannot give it a timeout. Too bad, use bearssl.

Fix a few bugs. sbearssl appears to be working.

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.

Moderately big hammer: force kill on s6-tlsd when it has nothing to write to the network

Revert big hammer. Data still needs to be flushed to the network even when the local app dies.
