e499f8e20a feat(kernel/inductive): relax conditions for an inductive datatype in Prop to be able to eliminate into Type 
The new relaxed version allows us to define the "accessability"
proposition and have an eliminator into Type.

See justification in the new comments at inductive.cpp

8723f5b613 fix(frontends/lean/inductive_cmd): inductive datatype elaborator was 'fixing' parameter mismatches. 
Given a datatype C with parameters As, if the declaration contained
(C Bs), the elaborator would silently replace it with (C As).

This bug would confuse users and make them believe they define something
different.

94cf10284a fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286 
The problem was that heq type is
    Pi {A : Type} (a : A) {B : Type} (b : B), Prop

The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.

The fix is to remove this assumption.

ca632cca13 feat(frontends/lean): add 'universe variable' command 
We can declare variables anywhere. So, we must also be able do declare
"universe" variables anywhere. Here is a minimal example that requires
this feature

```
-- We want A and B to be in the same universe
universe variable l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```

The following doesn't work because A and B are in different universes
```
variable A : Type
variable B : Type
definition tst := A = B
```

The following works, but tst is not universe polymorphic, since l is
one *fixed* global universe
```
universe l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```

This is not exclusive to equality.
It applies to any inductive datatype in Prop, containing only one
constructor with zero "arguments" (we say they are nullary).

BTW, the restriction to only one constructor is not needed, but it is
does not buy much to support multiple nullary constructors since Prop is
proof irrelevant.

b3e05a2fe9 refactor(frontends/lean/scanner): remove dependency to seekg and unget 
methods

It is not safe to use seekg for textual files. Here is a fragment from a
C++ manual:

seekg() and seekp()

This pair of functions serve respectively to change the position of stream pointers get and put. Both functions are overloaded with two different prototypes:

     seekg ( pos_type position );
     seekp ( pos_type position );

Using this prototype the stream pointer is changed to an absolute position from the beginning of the file. The type required is the same as that returned by functions tellg and tellp.

      seekg ( off_type offset, seekdir direction );
      seekp ( off_type offset, seekdir direction );

Using this prototype, an offset from a concrete point determined by
parameter direction can be specified. It can be:

          ios::beg	offset specified from the beginning of the stream
          ios::cur	offset specified from the current position of the stream pointer
          ios::end	offset specified from the end of the stream

The values of both stream pointers get and put are counted in different
ways for text files than for binary files, since in text mode files some
modifications to the appearance of some special characters can
occur. For that reason it is advisable to use only the first prototype
of seekg and seekp with files opened in text mode and always use
non-modified values returned by tellg or tellp. With binary files, you
can freely use all the implementations for these functions. They should
not have any unexpected behavior.

faee08591f fix(*): make sure elaborator and type_checker use the same "rules" for treating opaque definitions 
This is a big change because we have to store in constraints whether we can use the "relaxed" rules or not.
The "relaxed" case says that when type checking the value of an opaque definition we can treat other opaque definitions in the same module as transparent.

603dafbaf7 refactor(kernel): remove 'let'-expressions 
We simulate it in the following way:
1- An opaque 'let'-expressions (let x : t := v in b) is encoded as
      ((fun (x : t), b) v)
   We also use a macro (let-macro) to mark this pattern.
   Thus, the pretty-printer knows how to display it correctly.

2- Transparent 'let'-expressions are eagerly expanded by the parser.

7b15e558a2 refactor(kernel/converter): implement eta in whnf instead of is_def_eq. 
Without cumulativity, we do not have problems with Eta at whnf anymore.
When we had cumulativity, we could not not simply reduce
     (fun x : A, f x) ==> f
This step is correct only if domain(f) was definitionally equal to f.
Here is a problematic example for systems with cumulativity
Given, f : Type.{2} -> Bool
     (fun x : Type.{1}, f x)
