Jamey Sharp 426306376f
CNF conversion refactoring (#5547) 
* split sat2goal out of goal2sat

These two classes need different things out of the sat::solver class,
and separating them makes it easier to fiddle with their dependencies
independently.

I also fiddled with some headers to make it possible to include
sat_solver_core.h instead of sat_solver.h.

* limit solver_core methods to those needed by goal2sat

And switch sat2goal and sat_tactic over to relying on the derived
sat::solver class instead. There were no other uses of solver_core.

I'm hoping this makes it feasible to reuse goal2sat's CNF conversion
from places like the tseitin-cnf tactic, so they can be unified into a
single implementation.

@wintersteiger
This example exposes a bug in is_unique_value
```
(assert (= (fp.to_real ((_ to_fp 8 24) (_ bv4286579200 32))) (fp.to_real ((_ to_fp 8 24) (_ bv4286578944 32)))))
(check-sat)
```
It returns true for fp representations that map to NaN. It can only return true for fp values that are unique relative to having no other bit-vector representation so not corresponding to an equivalence class of values such as NaN.
I am having it return false. If there is a way to refine the test it will catch some earlier inferences.

Nikolaj Bjorner 09696e989e add missing lambda defs per #5509 
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).

@zwimer: I had to remove a different move constructor before in the same API due to a different bug that the coverage tool exposed. I was unable to reproduce the bug reported in #5493 in my environment, but the interaction with reference counting and move constructors is sufficiently opaque that I rather not have to fix more bugs introduced with move constructors in the API. I am therefore removing also this use of && and maybe this fixes #5493

Add AssertSoft String overload for Java Api (#5475) 
This adds a String overload for AssertSoft.
Previously only integer weights could have been used,
limiting the user. With Strings the user can now use
e.g. Java's BigInteger class converted to a String instead.
