Add (almost) compatibility with camlp4, without breaking support for camlp5

The choice between camlp4/5 is done during configure with flags
 -usecamlp5 (default for the moment) vs. -usecamlp4.

 Currently, to have a full camlp4 compatibility, you need to change
 all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI"
 into "`EOI" in grammar entries. I've a sed script that does that
 (actually the converse), but I prefer to re-think it and check a few
 things before branching this sed into the build mechanism.

 lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5
 and try to propose a common interface (cf LexerSig / GrammarSig).
 A few incompatible quotations have been turned into underlying code
 manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END
 parsable by both camlp4 and 5. See in particular the fate of
 <:str_item< declare ... end >>

 Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc).
 This forces to use camlp5 > 5.01.
