Taming the simpl evar hack that used to use negative evars.
Now we just generate evars in the given evar map.

At least, the test-suite isn't broken...

Removing almost all new_untyped_evar, and a bunch of Evd.add.
Ultimately all evars should be created with respect to a given
evar map, instead of using a global counter.

Removing unused code from Term_dnet.

Removing the last global evar generation in Term_dnet. The very
fact that the previous implementation was working is still black
magic to me, as evars may have collided in intriguing ways...

At least made the evar type opaque! There are still 5 remaining unsafe
casts of ints to evars.

- 2 in Evarutil and Goal which are really needed, even though the Goal
one could (and should) be removed;
- 2 in G_xml and Detyping that are there for completeness sake, but
that might be made anomalies altogether;
- 1 in Newring which is quite dubious at best, and should be fixed.

Get rid of the uses of deprecated OCaml elements (still remaining compatible with OCaml 3.12.1).

Made the filename of compiled files explicit, i.e. add a ./ prefix
whenever the filename was given alone. This caused strange behaviour
of coqtop that was compiling stuff we didn't want to just because
it was somewhere in its loadpath.

This is why FingerTree was not compiling, btw, as it had two files
equally named in two different paths.

Prettyp: avoid useless "let module"

 As hinted by X. Clerc, a "let module" induces some runtime cost,
 so let's try to avoid them when possible.

universes-buraliforti-redef.v : repair a match after Pierre B. syntax changes

 This file, which is currently expected to fail at the last line
 (with Universe Inconsistency), was actually failing earlier
 after Pierre Boutillier changed the patterns (parameters are required now).

 A final "Fail" will soon arrives here to avoid such issue in the future...

Uminus.v : prepare this test file for the use of Fail

 - Highlight the fact that the line defining "up" is the one which
   should fail.
 - Factor code with stdlib's Hurkens.v
 - This way, this test could become a "shouldnotfail" test by placing
   two final "Fail" (before the definitions of "up" and "paradox").
