This change allows endless restarts, similar to `respawn` but honors
`restart_sec`. There is no upper limit on the number of times Finit
tries to restart a crashing service. Same as `restart:-1`

When logged in from sulogin we cannot send IPC to Finit, not even
signals, to delegate reboot. For usability, attempt to tell reboot that
it's in sulogin mode -- provided the bundled sulogin is used -- to let
reboot trigger over to forced reboot.
We cannot do much about initctl, just document this as a limitation.

- Add `type:forking` service option to trigger guessing pidfile to
watch for, instead of `pid:!foo` option, which is not intuitive.
This option may likely also survive into the new file format :)
- Update docs and add examples
- Update start-stop-serv.sh test case with this new variant

- Check if watchdogd *and* `WDT_DEVNODE` exists before registering the
built-in watchdogd at boot
- Update bootstrap.md with this additional constraint
- Update config.md with references to bootstrap and the new constraint

Add support for monitoring environment files for services declared with
the `env:[-]/path/to/file` option. The default path to such files has
been chosen to follow Debian and Buildroot /etc/default/*

The <svc/foo> condition was created to synchronize starting services,
hence the abbreviation. Example: the Quagga ripd needs to start after
the zebra daemon to ensure its UNIX domain socket is active, otherwise
events may be lost.
However, considering that synchronization was implemented with UNIX PID
files, e.g. waiting for /var/run/quagga/zebra.pid to be created, the
condition abbreviation name <svc/foo> was hard to understand by most
newcomers to Finit. To make matters worse, a new feature to track or
even create PID files for services that don't create one themselves,
using the syntax 'pid:/path/to/foo.pid' was added.
Connecting the dots between these wasn't obvious.
This patch renames service conditions pid conditions and also adds
a compatibility wrapper to the Finit .conf parser. Any condition
given in old .conf files with 'svc/' prefix are internally renamed
'pid/', along with a LOG_INFO notice in syslog.

Finit v3.1 adds support for reloading /etc/finit.conf, document what
actually is read at runtime, compared to at bootstrap, and clarify
which stanzas are for what part of the boot process.

This patch extends the existing rlimit implementation to support setting
limits per service, run/task, inetd, and tty.
Use rlimit in /etc/finit.conf to change the global setting, which is
then inherited to each /etc/finit.d/*.conf. For each .conf file the
rlimit is reinitialized to the global finit.conf settings.
Also, add `unlimited` keyword, to replace the now deprecated `infinity`
keyword. The latter is however kept, for compatibility with previous
releases, for the foreseeable future.

All this code did was trigger prctl() to set process name to "console",
which you could use as a simple means of figuring out if a process was
started from the system console.
There are other ways to do this, which Finit should not be involved in.
