Upper layers are still not able to handle mutual records though.

This brings more compatibility with handling of mutual primitive records
in the kernel.

This is a first step towards the acceptance of mutual record types in the
kernel.

When inferring [u <= v+k] I replaced the exception and instead add
[u <= v]. This is trivially sound and it doesn't seem possible to have
the one without the other (except specially for [Set <= v+k] which was
already handled).
I don't know an example where this used to fail and now succeeds (the
point was to remove an anomaly, but the example
~~~
Module Type SG. Definition DG := Type. End SG.
Module MG : SG. Definition DG := Type : Type. Fail End MG.
~~~
now fails with universe inconsistency.
Fix #7695 (soundness bug!).

It was used in some examples, but never fully documented

- we always rename
- we compile {clear}/view to /view{clear}

I think the bug was introduces when apply_type was made safe.
In the test joint to #7255 rewrite (setoid case) generates an
ill-typed goal and apply_type raises a Pretype_error.
It is unclear to me why the tactic monad does not turn the
pretype_error into a UserError

There's probably a proof of false using subtyping if someone wants to
look.
NB: the checker doesn't handle algebraics on the right.

When initilazing the load path, coqtop adds implicit bindings for stdlib
and for the current directory (-R stdlib Coq -R . ""). In case of
a clash, the binding of the current directory had priority, which makes
it impossible to edit stdlib files (when they Require files from the
same directory) using PG, or from CoqIDE when launched from the directory
containing the file.
Example to reproduce the problem:
```
cd plugins/omega
coqide Omega.v
```
some of the Requires will fail.
