7772c16033 refactor(kernel): add unfold_opaque flag to normalizer, modify how type checker uses the opaque flag, remove hidden_defs, and mark most builtin definitions as opaque 
After this commit, in the type checker, when checking convertability, we first compute a normal form without expanding opaque terms.
If the terms are convertible, then we are done, and saved a lot of time by not expanding unnecessary definitions.
If they are not, instead of throwing an error, we try again expanding the opaque terms.
This seems to be the best of both worlds.
The opaque flag is a hint for the type checker, but it would never prevent us from type checking  a valid term.

ae01d3818d fix(frontends/lean/parser): parse_type method 
The parser had a nasty ambiguity. For example,
    f Type 1
had two possible interpretations
    (f (Type) (1))
or
    (f (Type 1))

To fix this issue, whenever we want to specify a particular universe, we have to precede 'Type' with a parenthesis.
Examples:
    (Type 1)
    (Type U)
    (Type M + 1)

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.

4357c9196e feat(kernel/metavar): make sure that a metavariable 'm' can only be assigned to a term that contains free variables available in the context associated with 'm' 
This commit also simplifies the method check_pi in the type_checker and type_inferer.
It also fixes process_meta_app in the elaborator.
The problem was in the method process_meta_app and process_meta_inst.
They were processing convertability constrains as equality constraints.
For example, process_meta_app would handle

    ctx |- Type << ?f b

as

    ctx |- Type =:= ?f b

This is not correct because a ?f that returns (Type U) for b satisfies the first but not the second.

51aee83b70 refactor(kernel/metavar_env): use the same approach used in the class environment in the class metavar_env 
This modification was motivated by a bug exposed by tst17 at tests/kernel/type_checker.
metavar_env is now a smart point to metavar_env_cell.
ro_metavar_env is a read-only smart pointer. It is useful to make sure we are using proof_state correctly.

example showing that the approach for caching metavar_env is broken in the type_checker

f97c260b0b refactor(kernel/environment): add ro_environment 
The environment object is a "smart-pointer".
Before this commit, the use of "const &" for environment objects was broken.
For example, suppose we have a function f that should not modify the input environment.
Before this commit, its signature would be
       void f(environment const & env)
This is broken, f's implementation can easilty convert it to a read-write pointer by using
the copy constructor.
       environment rw_env(env);
Now, f can use rw_env to update env.

To fix this issue, we now have ro_environment. It is a shared *const* pointer.
We can convert an environment into a ro_environment, but not the other way around.

ro_environment can also be seen as a form of documentation.
For example, now it is clear that type_inferer is not updating the environment, since its constructor takes a ro_environment.

aed8b1fc73 fix(tests/library/rewriter): app_rewriter1_tst 
There was a bug in the app_rewriter1_tst. If we apply the ADD_COMM RW to
f(0), then the result should be f(0) since there is nothing to do for
ADD_COMM.

    f(0) = f(0)

The proof for this equality should be Refl(Nat, f(0)). But it was

    Refl(Nat -> Nat, f)

which is wrong. Somehow, the previous kernel didn't detect this type
mismatch and recent changes of the kernel found the problem.

I fixed the bug and re-enable the test as it was.
