Subject: Unification constraint handling (#4763, #5149)

Refine fix for bug #4763, fixing #5149

Tactic [Refine.solve_constraints] and global option

Adds a new multi-goal tactic [Refine.solve_constraints] that forces solving of
unification constraints and evar candidates to be solved. run_tactic now calls
[solve_constraints] at every [.], preserving (mostly) the 8.4/8.5 behavior of tactics.
The option allows to unset the forced solving unification constraints at
each ".", letting the user control the places where the use of
heuristics is done.

Fix test-suite files too.
