[v6,1/4] qapi: Introduce UsernetTcpState

Commit Message

Fam Zheng May 4, 2018, 7:42 a.m. UTC

This will be a drop-in replacement for the current TCPS_ macro/enum and
what we will return to users in the coming qmp command.

The next patch will drop TCPS_ to avoid duplication and keep further
refactoring simple.
