net-misc/connman: Fix iptables and xtables issues
Fixes issues with iptables, xtables, and glibc when building and running
connan. Specifically, the patch, connman-1.31-iptables-1.6.0.patch,
fixes the icompatibilities between iptables and connman (due to an ABI
break in iptables-1.6.0). The patch, connman-1.31-xtables.patch, uses
some preprocessor tricks to route around incompatibilies seen between
newer Linux kernels and glibc when both net/if.h and linu/if.h are
included in the same source.
