Instead of the MAX_EVTCHNS(d) macro, use d->max_evtchns instead. This
avoids having to repeatedly check the ABI type.

In the output of the 'e' debug key, print some ABI specific state in
addition to the (p)ending and (m)asked bits.
For the 2-level ABI, print the state of that event's selector
bit. e.g.,
(XEN) port [p/m/s]
(XEN) 1 [0/0/1]: s=3 n=0 x=0 d=0 p=74
(XEN) 2 [0/0/1]: s=3 n=0 x=0 d=0 p=75

Use functions for the low-level event channel port operations
(set/clear pending, unmask, is_pending and is_masked).
Group these functions into a struct evtchn_port_op so they can be
replaced by alternate implementations (for different ABIs) on a
per-domain basis.
