INADDR_ANY bind in a multiip jail

[Meno Abels]

Hello,

i had made a patch for 5_X (kern/69064) jail code which enables ipv6 and
multi ip numbers to a jail. 
I currently solved the INADDR_ANY binding to map to the first ip of
the jail. But this is not really the good solution it would be better to bind 
to all ip's of the jail. Which are simple to determine the ip number which
are needed. But how i change in_pcbbind to support multiip binds. 
The problem is, there is only one pcb which can only bound to one
ip or just INADDR_ANY. But now i need a pcb which is able to bind to
two or more ip's. This is not intended in the current code. But to change
this it will be a huge change in the current datastructures of the kernel
networking part.
I don't like to change so much code at once so i ask you is there any
other clue to solve the INADDR_ANY mapping to a defined number of 
ip's.

thanks in advance
