refactor(library/data/prod): break into pieces to reduce dependencies

prod is needed for some automatically generated constructions.
So, it is important it is loaded in the environment as early as possible.

fix(emacs/lean-syntax): syntax highlight, issue #306
...
1- FIXED structure foo := (bar : Type) -- the name of structures is not highlighted
2- NOT FIXED check foo-- this comment is not highlighted
3- FIXED check Type.{5} -- Type is not highlighted
4- FIXED definition bar{thisishighlighted : Type} := foo
5- FIXED definition bar2 {thetypeofthisvariableisnothighlighted :Type} := foo
Have no idea what is going on with 2. I'm not sure if this is our bug,
or Emacs code we depend on.

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.
