Joachim Nilsson 03573b41ca Add support for a deny filter syntax to inetd services
This patch changes the syntax for custom inetd services and adds support
for deny filters.  The new syntax is:

    inetd service/proto[@iface,!iface,...] </path/to/cmd | internal[.service]>

This means the second column now defines what@from and the third to/what
process.  For internal services on a custom port the internal.service
syntax must be specified, so Finit can properly bind the inetd service
to the correct plugin.  Here follows a few examples:

    inetd time/udp                    wait [2345] internal                -- UNIX rdate service
    inetd time/tcp                  nowait [2345] internal                -- UNIX rdate service
    inetd 3737/tcp                  nowait [2345] internal.time           -- UNIX rdate service
    inetd telnet/tcp@*,!eth1,!eth0, nowait [2345] /sbin/telnetd -i -F     -- Telnet service
    inetd 2323/tcp@eth1,eth2,eth0   nowait [2345] /sbin/telnetd -i -F     -- Telnet service
    inetd 222/tcp@eth0              nowait [2345] /sbin/dropbear -i -R -F -- SSH service
    inetd ssh/tcp@*,!eth0           nowait [2345] /sbin/dropbear -i -R -F -- SSH service

Access to telnet on port `2323` is only possible from interfaces `eth0`,
`eth1` and `eth2`.  The standard telnet port (`23`) is available from
all other interfaces, but also `eth2`.  The `*` notation used in the ssh
stanza means *any* interface, however, here `eth0` is not allowed.

NOTE: This patch breaks syntax compatibility with Finit v1.12!

Joachim Nilsson 1a1f24721f Refactor: introduce telinit and a new initctl tool w/ API
- Reduce size of `helpers.c`, for linking against new `initctl` tool,
  by moving out functions to `pid.c` and `exec.c`
- Add `AF_UNIX` API to Finit, to complement old `/dev/initctl` FIFO
- Let old FIFO API be used by init/telinit: `init <q | 1-9>`
- Move all advanced initctl code from `client.c` to `initctl.c`, yes
  its a bit confusing to call the *new* tool the same as the old FIFO
  but this is more in line with what, e.g Upstart does.
- Move all advanced server side code from `plugins/initctl.c` to `api.c`
- Update TODO with upcoming inetd syntax change and dynamic events.
- Temporarily fix display of inetd services from `initctl status -v`

Joachim Nilsson 24e1d284ad Add support for finit <stop|start|reload|restart> JOB
This patch further extends the capabilities of the client with the
ability to control the running state of services:

    finit <stop|start|reload|restart> JOB

Since services can now exist with multiple instances the concept of
"jobs" is introduced in this patch.  A job is a numeric identifier of
the form `NUM[:NUM]`, the latter `:NUM` is the new instance syntax
introduced earlier.  See the output of `finit status` for the JOB id.

Also, with the introduction of multiple instances we broke support for
multiple related inetd services.  This became obvious when the shiny new
`finit status` was tested ... hence, this patch also contains fixes to
the inetd support.

Joachim Nilsson 2026486fda Refactor: Cleanup and expand client code to support <version|q|reload|debug>
Further refactoring of the client code.  Supported commands:

- debug:   Toggle PID 1 debug flag
- version: Show Finit version or custom header string
- reload:  Reload config files in /etc/finit.d/, same as SIGHUP

Also supported is the legacy 'init q' command, to reload config.

The 'status' command now supports an optiona '-v', either as an
argument to init itself, or as argument to the command.  When it
is given 'status' lists verbose information about all services.
Currently only the service arguments are listed.
