Logging facility for spacer plus minor improvements (#3368) 
* [spacer] logging solver events

New option fp.spacer.trace_file='file.log' enables logging solving events
into a file.

These events are useful for debugging the solver, but also for visualizing
the solving process in a variety of ways

* [spacer] allow setting logic for solvers used by spacer

* [spacer] option to set arithmetic solver explicitly

* [spacer] improve of dumping solver_pool state for debugging

* fix propagate_ineqs to handle strict inequality
