This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.

This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Historicallly, hpdelim accepted ":" or "/" as a port delimiter between
hosts (or addresses) and ports. These days most of the uses for "/"
are no longer accepted, so there are several places where it checks the
delimiter to disallow it. Make hpdelim accept only ":" and use hpdelim2
in the other cases. ok djm@

OpenBSD and NetBSD require the caller to free strings returned
bu the login_* functions, but FreeBSD requires that callers don't.
Fortunately in this case, we can harmlessly leak as the process is
about to exec the shell/command.

sigaction(2). This wrapper blocks all other signals during the handler
preventing races between handlers, and sets SA_RESTART which should reduce
the potential for short read/write operations.

runs with user privilege now that we no longer support running sshd with
privilege separation disabled, but as long as the privsep skeleton is there
we should follow the rules.

This change stops including the old packet_* API by default and makes
each file that requires the old API include it explicitly. We will
