b64f45a8ba Remove unused advanced timing constraint API 
This API was simply an attractive nuisance as no code was ever developed
to actually process timing constraints (other than clock constraints
which use a different API).

While I do want to consider basic false path support, among other
things, in the near future; I plan for this to use a new API that
doesn't add complexity to the BaseCtx/Context monstrosity and that is
easier to use on the timing analysis side.

a30043c8da Fix assorted bugs in FPGA interchange. 
Fixes:
 - Only use map constant pins during routing, and not during placement.
 - Unmapped cell ports have no BEL pins.
 - Fix SiteRouter congestion not taking into account initial expansion.
 - Fix psuedo-site pip output.
