Addresses Julien's review no.1:

- No superfluous white space
- No camel case
- No unauthorized open
- Longic_const.tinteger -> Cil.lone, Cil.lzero
- lscope -> Lscope.t
- lscope becomes abstract
- 'with non-void logic scope' -> 'on purely logical variables'
- Make lscope be part of env
- Discard all the translation in a new module: At_with_lscope
- No extra variable for size
- Cil.(theMachine.typeOfSizeOf) instead of Cil.intType
- No superfluous block for storing_loops
- mem_infos -> memory_infos
- Prevent GMP result (actually already done previously)
- record for malloc and free
- H_malloc_free = Cil_datatype.Fundec.Hashtbl
- dedicated insert_malloc_and_free_stmts in Visit
- Kernel_function.is_entry_point for testing main function
- no visit in term_has_lv_from_vi and effective_lscope_from_pot
- term_has_lv_from_vi moved to Misc
- Passing kf to add_malloc_and_free_stmt instead of fundec
- Less @ during the insertion of free stmts
- ty_array -> ty_ptr
- Typos
- Comments on:
  - Exported functions in MLIs
  - Computation of pre in put_block_at_label
  - Use of global scope for Env.Varname.get
  - Description of mk_storing_loops
  - New binding in mk_storing_loops
  - Description of effective_lscope_from_pred_or_term
  - Motivation of the over-approximation on t_size
