86699b42f6 Switch to potentially-sparse net users array 
This uses a new data structure for net.users that allows gaps, so
removing a port from a net is no longer an O(n) operation on the number
of users the net has.

ddb084e9a8 archapi: Use arbitrary rather than actual placement in predictDelay 
This makes predictDelay be based on an arbitrary belpin pair rather
than a arc of a net based on cell placement. This way 'what-if'
decisions can be evaluated without actually changing placement;
potentially useful for parallel placement.

A new helper predictArcDelay behaves like the old predictDelay to
minimise the impact on existing passes; only arches need be updated.

e6006805ce Make EXTREFB handling more robust 
Avoids a segfault if an EXTREFB does not connect directly to its associated DCUA.
Also adds location constraints specifically for EXTREFB.
