[PATCH] Fix for broken unix_accept

[Lars Heete <hel@xxxxxxxx>]

Hello,

the accept call on unix-domain sockets in current 2.3 Linux is broken.
Instead of waiting for an incoming connection, it returns ENOTCONN. The problem 
is the use
of skb_recv_datagram, which checks for TCP_ESTABLISHED state before waiting.
My solution is to use an own unix_wait_for_connect function, similar to 
wait_for_packet
in core/datagram.c, but without unneeded error checks.
