Since Linux 2.6.4 the SOCK_SEQPACKET socket type is available for UNIX
domain sockets on Linux. It is intended for; "a sequenced-packet socket
that is connection-oriented, preserves message boundaries, and delivers
messages in the order that they were sent." which sounds like us.

When calling initctl early in the boot process, e.g. just when Finit is
switching to the final runlevel, it may take a few milliseconds for it
to actually be ready to process our request.
This patch adds poll() to both the write(REQ) and the read(RSP) steps
to prevent from getting weird errors when Finit is busy. The timeout
is currently 2 sec in both directions, which should be enough.

Instead of just walking /run/finit/cond, also show the source of each
condition. The hook and net conditions are hard-coded to init[1] atm.
and unknown conditions are shown as unknown[0].

This change is one of the required intermediate steps to remove the
shared memory store for all svc_t, this in turn to avoid any external
programs manipulating the internal memory of PID 1.

We need the name client.c for the client side of api.c, so let's rename
the client to its traditional name.
