Summary:                    [patch] FXO channels "hookstate" incorrect on
startup
Description: 
Referencing bug 13786 (http://bugs.digium.com/view.php?id=13786) which
attempts to work around an underlying problem in userspace (chan_dahdi). 
The issue seems to be (as described by tzafrir):

It seems to expose a bug(?) in zaptel/dahdi where chan->rxhooksig is set
to RX_HOOKSIG_INITIAL at the end of chanconfig() which leaves the channel's
state there "uninitialized" and even if the channel driver knows better it
cannot override this decision. But I'm not sure what's the intended
behaviour, so I avoid a seperate bug report on that for now.

This is manifested in that I cannot make outbound calls on an FXO card
(Using FXSKS signalling) until I've received an incoming call resetting the
hookstate to offhook (A single ring is good enough), or alternatively,
disconnecting and reconnecting the telephone line.

wctdm24xxp, wctdm: Detect if our hookstate has been set back to the
initial state.

Check if our hookstate has been set back to the initial state, typically
the
result of a chanconfig, and if so, if we're an FXO port, forget our
current
battery state.  This allows the driver to determine and report again what
the
hook state of the port is.
