parking: parked calls live, on the dashboard and Home, pick up from Home

res_parking was configured in M0 (700, slots 701-720, slot hints); this
makes parked calls visible. ParkingTracker loads ParkedCalls and follows
ParkedCall/UnParkedCall/ParkedCallTimeOut/ParkedCallGiveUp; everyone
gets parked.updated/parked.removed. Who parked comes from
ParkerDialString.

A blind transfer to 700 parks without running Park() in the dialplan,
so the live call's "parked" state now comes from those events by
ParkeeLinkedid; the picking-up phone runs ParkedCall() while talking,
which no longer counts as parked.

Web: "Parked calls" on the Dashboard and on Home, where "Pick up 701"
calls the slot like Call back (softphone, or the desk phone first).

CDR fixture park-pickup (recorded: 101 parks an inbound call, 103 picks
it up); the call counts as answered by 101 with 103 in rang. e2e m8-t2
with real phones: park by blind transfer, hint InUse, both lists, pick
up from Home, a second park on 702 (findslot = next) picked up by
dialing it from another phone. Specs 01/04/05 note what was verified.
