This was decided during the Fall WG (2017).
The aliases that are kept as deprecated are the ones where the difference
is only a prefix becoming a qualified module name.
The intention is to turn the warning for deprecated notations on.
We change the compat version to 8.6 to allow the removal of VOld and V8_5.

Suppose we declare : Notation foo := bar (compat "8.3").
Then each time foo is used in a script :
- By default nothing particular happens (for the moment)
- But we could get a warning explaining that
"foo is bar since coq > 8.3".
For that, either use the command-line option -verb-compat-notations
or the interactive command "Set Verbose Compat Notations".
- There is also a strict mode, where foo is forbidden : the previous
warning is now an error.
For that, either use the command-line option -no-compat-notations
or the interactive command "Unset Compat Notations".
When Coq is launched in compatibility mode (via -compat 8.x),
using a notation tagged "8.x" will never trigger a warning or error.

A sub-module N in BinNat now contains functions add (ex-Nplus),
mul (ex-Nmult), ... and properties.
In particular, this sub-module N directly instantiates NAxiomsSig
and includes all derived properties NProp.
Files Ndiv_def and co are now obsolete and kept only for compat

BinPos now contain a sub-module Pos, in which are placed functions
like add (ex-Pplus), mul (ex-Pmult), ... and properties like
add_comm, add_assoc, ...
In addition to the name changes, the organisation is changed quite
a lot, to try to take advantage more of the orders < and <= instead
of speaking only of the comparison function.
The main source of incompatibilities in scripts concerns this compare:
Pos.compare is now a binary operation, expressed in terms of the
ex-Pcompare which is ternary (expecting an initial comparision as 3rd arg),
this ternary version being called now Pos.compare_cont. As for everything
else, compatibility notations (only parsing) are provided. But notations
"_ ?= _" on positive will have to be edited, since they now point to
Pos.compare.
We also make the sub-module Pos to be directly an OrderedType,
and include results about min and max.

As for power recently, we add a specification in NZ,N,Z,
derived properties, implementations for nat, N, Z, BigN, BigZ.
- For nat, this sqrt is brand new :-), cf NPeano.v
- For Z, we rework what was in Zsqrt: same algorithm,
no more refine but a pure function, based now on a sqrt
for positive, from which we derive a Nsqrt and a Zsqrt.
For the moment, the old Zsqrt.v file is kept as Zsqrt_compat.v.
It is not loaded by default by Require ZArith.
New definitions are now in Psqrt.v, Zsqrt_def.v and Nsqrt_def.v
- For BigN, BigZ, we changed the specifications to refer to Zsqrt
instead of using characteristic inequations.
On the way, many extensions, in particular BinPos (lemmas about order),
NZMulOrder (results about squares)
