343a9a690e feat(emacs/lean-type): add lean-show-type-add-to-kill-ring option 
If a customization option 'lean-show-type-add-to-kill-ring' is non-nil
and a user runs 'lean-show-type' by explicitly typing 'C-c C-t',
lean-mode saves the displayed type information message into kill-ring
, which can be pasted by yank (C-y) command.

7231aa0d73 fix(library/module): allow multiple calls to import_modules with the same modules 
The idea is to store a set of already imported files.
This feature is useful when using the import_modules API directly (e.g.,
from javascript).

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
```

235b8975d2 feat(kernel/inductive): K-like reduction in the kernel 
Given (H_1 : a = a), we have that
      eq.rec H_2 H_1
reduces to H_2

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.

39645390ff chore(util/*): add cstddef header before including gmp.h/mpfr.h 
Reference: https://gcc.gnu.org/gcc-4.9/porting_to.html

------

Header <cstddef> changes

The <cstddef> header was updated for C++11 support and this breaks some
libraries which misuse macros meant for internal use by GCC only. For
instance with GMP versions up to 5.1.3, you may see:

/usr/include/c++/4.9.0/cstddef:51:11: error: ‘::max_align_t’ has not been declared
   using ::max_align_t;
           ^
Another possible error is:

someheader.h:99:13: error: ‘ptrdiff_t’ does not name a type

A workaround until libraries get updated is to include <cstddef> or
<stddef.h> before any headers from that library.
