refactor(library/init): define prod as an inductive datatype
...
Motivation: prod is used internally in the definitional package.
If we define prod as a structure, then Lean will tag pr1 and pr2 as
projections. This creates problems when we add special support for
projections in the elaborator. The heuristics avoid some case-splits
that are currently performed, and without them some files break.

This renaming is because type_quotient is a nonstandard name. I've had a discussion with Egbert
Rijke, Steve Awodey and Dan Licata, and the consensus for a better name was 'quotient'. I had to
make changes in src/kernel/hits/hits.cpp, I renamed g_type_quotient* by g_hit_quotient* (to avoid
name clash the standard library quotient, although I don't know whether that name clash would
matter).

fix(frontends/lean/parser): must save state of name_generator in parser snapshot
...
To provide typing and auto-completion information, we create a
background process by starting lean with the option --server.
In "server" mode, we create snapshots of the parser state.
The idea is to be able to quickly reprocess a file when the user makes a
modification. This commit fixes a bug in the snapshot operation.
It was not saving in the snapshots the unique name generator used by the parser.
By creating a fresh name generator, we may accidentally
assign the same internal name to two different constants.
This bug triggered the crash described in issue #593 .
This commit fixes the test in the comment

we must also check the universe levels when applying the optimization for
constraints of the form:
f.{l_1 ... l_k} a_1 ... a_n =?= f.{l_1' ... l_k'} b_1 ... b_n
The optimization tries to avoid unfolding f if we can establish that
a_i is definitionally equal to b_i for each i in [1, n]
