s_client accepts host/port as positional argument.

This allows the user to provide the target host and optional port to
openssl s_client as an optional positional argument, rather than as the
argument to the -connect flag. This rationalises the user experience of
s_client: given that the only logical purpose of s_client is to connect
to a host, it is difficult to understand why there is an (effectively
mandatory) command option to pass to make that happen.

This patch forbids providing *both* -connect and the positional
argument, because it would likely be too difficult to reconcile.
Otherwise, using the positional argument behaves exactly the same as
using -connect does.

drop some no-longer-relevant TODO(TLS1.3) entries

We prevent compression both when the server is parsing the ClientHello
and when the client is constructing the ClientHello.  A 1.3 ServerHello
has no way to hand us back a compression method, and we already check
that the server does not try to give us back a compression method that
we did not request, so these checks seem sufficient.

Weaken the INSTALL note slightly, as we do now expect to interoperate
with other implementations.
