OpenSSL to 1.01h for CVE-2014-0224, others.
Fix SFTP subsystem; strengthen server key and policy.
Add `api` parameter to indicate success/failure with HTTP status.

Also, accept either GET or POST for requests to `/setup/password` and
`/setup/finish`.
Always store `*.pid` files on volatile storage.

This updates the service supervision scripts, `nginx`, and `avahi` to keep its
PID and run control / state files on temporary in-memory storage that is
automatically erased on reboot. These files have no meaning outside of a
running system.

We're doing this as a defensive measure. An unclean shutdown can occasionally
leave a PID file truncated but not unlinked; Avahi, in this case, has a bug
where it interprets the empty file to mean PID zero (likely because of sloppy
`atoi` usage or missing error checking for `strtoul`) and thinks there's another
copy already running. For historical reasons, PID zero has special meaning in
UNIX-like operating systems (it's sometimes referred to as the scheduler or the
"swapper", and is actually part of the kernel rather than a normal process).
