Set officially the minimal OCaml requirement to 3.12.1

 Anyway, a few syntactic features of 3.12 were already used here and
 there (e.g. local opening via Foo.(...), or the record shortcut
 { field; ... }). Hence compiling with 3.11 wasn't working anymore.

 Already take advantage of the following 3.12.1 features :
 - "module type of ..." in CArray, CList, CString ...
 - "ocamldep -ml-synonym" : no need anymore to hack the ocamldep output
   via our coqdep to localize the .ml4 modules :-)

 The -ml-synonym option (+ various bugfixes) is the reason for asking
 3.12.1 directly and not just 3.12.0. After all, if debian stable is
 providing 3.12.1, then everybody has it ;-)
