Modularization of BinNat + fixes of stdlib
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
