af42078205 fix(kernel): incorrect use of scoped_map
This commit also adds a new test that exposes the problem.
The scoped_map should not be used for caching values in the normalizer and type_checker. When we extend the context, the meaning of all variables is modified (we are essentially performing a lift). So, the values stored in the cache are not correct in the new context.

1a02abf7b2 feat(util/script_state): add a lua hook function that checks for the interrupt flag
This is a very convenient feature for interrupting non-terminating user scripts.
Before this commit, the user had to manually invoke check_interrupt() in potentially expensive loops. Now, this is not needed anymore.

Remark: we still have to check whether this trick works with LuaJIT or not.

f80106a895 chore(*): use 'explicit operator bool' everywhere.
operator bool() may produce unwanted conversions.
For example, we had the following bug in the code base.

...
   object const & obj = find_object(const_name(n));
   if (obj && obj.is_builtin() && obj.get_name() == n)
...

obj.get_name() has type lean::name
n              has type lean::expr

Both have 'operator bool()', then the compiler uses the operator to
convert them to Boolean, and then compare the result.
Of course, this is not our intention.

After this commit, the compiler correctly signs the error.
The correct code is

...
   object const & obj = find_object(const_name(n));
   if (obj && obj.is_builtin() && obj.get_name() == const_name(n))
...

74dfdd02de feat(util): add primitives for checking the amount of available stack space
Recursive functions that may go very deep should invoke the function check_stack. It throws an exception if the amount of stack space is limited.

The function check_system() is syntax sugar for
    check_interrupted();
    check_stack();

83aaf64318 fix(library/tactic): memory leaks
Proof/Cex builders and tactics implemented in Lua had a "strong reference" to script_state. If they are stored in the Lua state, then we get a cyclic reference.
That is, script_state points to these objects, and they point back to script_state.

To avoid this memory leak, this commit defines a weak reference for script_state objects. The Proof/Cex builders and tactics now store a weak reference to the Lua state.
