Ide: more reorganisation and cleanup

 - Avoid using Util which depends on Compat and hence Camlp4
 - Instead, a small Minilib module specific to coqide, which
   duplicate 5 functions from Util (50 lines)
 - some dead code removal
 - the coqlib variable is asked to coqtop
 - remove obsolete Util.check_for_interrupt

 This way, coqide only depends on 3 files outside ide/ :
 Coq_config, Flags, Ide_intf. Makefile and ocamlbuild are adapted
 accordingly.

TODO: how should we signal coqide error, warnings, etc ?
 For the moment, some Printf.eprintf, some failwith.
 To uniformize later...
