Don't show DCC "Handshake failed" message twice

Browse Source 
parse_offer_params() was being run unconditionally by check_dcc_init() even if it didn't find a
custom init_func() to call, which is the usual case.  It then gets called again by the hardwired
DCC init function, which led to the error message appearing twice.  This has check_dcc_init() only
call parse_offer_params() when its about to dispatch to a custom init func.

This also improves the message a bit (making it [host:port] rather than the other way around) and
combines the 'privileged port' message and "zero address" message together.

[Changes 1.2.2]
* Don't show DCC "Handshake failed" message twice, improve the message itself
and use the same one for privileged port / zero address. (caf)
* Use the same format in /DCC LIST for all waiting offers and tweak
the DCC_BAR_TYPE 1 format to show DCC state. (caf)
