Rename 'user' to 'user_solver' #5586 (#5587) 
Issue #5586 reported that Android builds (targetting, e.g., x86) failed
to compile due to a conflict between:

* `struct user` in `sys/user.h`; and
* `namespace user` in z3's `user_solver.h`

This issue is resolved by renaming `namespace user` to `namespace
user_solver` (matching the header name) to avoid this conflict.

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.
