As soon as we collect a PID we should cancel any outstanding timer
actions. Because we may very soon svc_del() it ...

Some C-lib, like GLIBC, convert NULL to <nil> when printing %p,
which we shouldn't rely on since others just bite the dust.

Initial refactor of the tty implementation to use the service/run/task
general backend. This enables all the features of services also for
ttys, except logging because it makes no sense.
Work in progress:
- plugins/tty.c does not work anymore, could possibly be removed in
favor of usinga (a new) condition instead (if-tty-exists)
- fallback tty does not work anymore, should we remove it, or can we
handle it as an optional built-in with (a new) condition?
- @console does not work anymore, needs to generate N cloned services

Calling `tree /tmp` causes too long execution time and Travis timing out
the job. So let's install to a sane directory.

- List /etc/finit.conf
- Allow edit of /etc/finit.conf, using finit/finit.conf or NULL
- Add helpful question to edit /etc/finit.conf if no edit arg.
- Show available files if delete has no arg, like disable

The main purpose of this patch is to remove top-level cgroups when they
are remvoed from finit.conf. However, this is tricky, becasue there may
still be supervised services (and children of them) running. We must
postpone removal until a cgroup.events change. To make matters worse,
events may arrive out-of-order, i.e. the last-child event for the parent
cgroup before the sub-group.
A spin-off from this patch is that we can now support arbitrarily long
group names and group config. (Only applies to top-level cgroups, not
run/task/services.)
Limitations:
- Processes in "removed" cgroups are not migrated/orphaned, the reasons
are several: overhead and complexity and the fact that memory cannot
be migrated
- A lingering child of a moved service may prevent an old top-level
cgroup from being removed.

We have these neat extras for added value, if they should fail, for
whatever reason, we still want to present 'top' to the user, which may
have to use 'reset' if exited improperly and lost cooked/cursor.

We check it everywhere else, and a log message for failing to move PID 1
to the init cgroup is useful as well.

No need to zero out whole buffer for strlcat(), or other string check
ops. Also drop a few completely useless memset() calls.

- Set TTY in raw mode to be able read a single char at a time
- Hide cursor
- Trap 'q', Ctrl-C, Ctrl-\ and SIGTERM to restore TTY and cursor
