Gunnar Beutner 532db9f768 Kernel: Treat 0.0.0.0 as a loopback address
This matches what other operating systems like Linux do:

$ ip route get 0.0.0.0
local 0.0.0.0 dev lo src 127.0.0.1 uid 1000
    cache <local>

$ ssh 0.0.0.0
gunnar@0.0.0.0's password:

$ ss -na | grep :22 | grep ESTAB
tcp   ESTAB      0      0   127.0.0.1:43118   127.0.0.1:22
tcp   ESTAB      0      0   127.0.0.1:22      127.0.0.1:43118
