Make ss aware of the new "bound-inactive" pseudo-state for TCP (see
Linux commit 91051f003948 ("tcp: Dump bound-only sockets in inet_diag.")).
These are TCP sockets that have been bound, but are neither listening nor
connecting.
With this patch, these sockets can now be dumped with:
* the existing -a (--all) option, to dump all sockets, including
bound-inactive ones,
* the new -B (--bound-inactive) option, to dump them exclusively,
* the new "bound-inactive" state, to be used in a STATE-FILTER.
Note that the SS_BOUND_INACTIVE state is a pseudo-state used for queries
only. The kernel returns them as SS_CLOSE.
The SS_NEW_SYN_RECV pseudo-state is added in this patch only because we
have to set its entry in the sstate_namel array (in scan_state()). Care
is taken not to make it visible by users.
