Improve userman

Closes #58

See merge request frama-c/e-acsl!241

[userman] replace section 'Limitations of E-ACSL Monitoring Libraries' by 'Supported Systems' + improved index

Remove useless ?init from Env

See merge request frama-c/e-acsl!248

Memory instrumentation moved in Mmodel_translate.

See merge request frama-c/e-acsl!247

Subtraction between pointers gives integer.

Bugfix for non declared variables when using \at

See merge request frama-c/e-acsl!230

- BTS #!1354 is actually not yet fixed
- Logic functions and logic global variables are not yet supported
- Better description of features that are not yet implemented
- Add missing \cinput files

- Stack of varinfos instead of list of varinfos
- stmts_block -> block_to_stmt, which results in less @
- fold_right instead of map+ref
- Optimizing with SkipChildren
- Useless parentheses. Typo. Indentation. No if not then else. begin...end instead of (...) for imperative constructs.

- Less lengthy closure in index_from_sizes_and_shifts
- String on multiple lines.
- Comment for extend_stmt_in_place
- Detail pattern matching in vblock
- List.exists instead of List.find
- mem instead of find in At_with_lscope.remove_all
- effective_lscope -> is_used

 - Sad goodbye to insert_before_element_under_condition
 - ~label instead of ~pre
 - No superfluous Env.Varname.get
 - Gmp only allowed
 - Dataflow analysis allowed
 - Using exception for term_has_lv_from_vi
 - Fix incorrect assert false from effective_lscope_from_pred_or_term
 - fold_left for index_from_sizes_and_shifts

MAJOR:
- malloc and free
  - Distinct tables for malloc and free
  - Efficient insertion of free and malloc
  - Remove entries for malloc and free when they are not needed anymore
- Using kf instead of fundec
- Using closure of vi_at: not (straightforwardly) possible
- Logic scope:
  - No Lscope.top
  - Proper reseting of the lscope
  - Proper binding of logic variables
  - Module Env.Logic_scope
- Comment for the over-approximation of t_size

STYLE:
- No useless new lines
- Spaces
- Parentheses
- Latex style for formula in comment of index_from_sizes_and_shifts
- match -> function
- Logical variable -> logic variable
- Renaming:
  - add_to_lscope ->  extend_lscope
  - memory_infos_from_quantifs -> sizes_and_shifts_from_quantifs
  - res -> sizes_and_shifts, memory_infos -> sizes_and_shifts
- Typos
- Forward references at the end of the mli
- Consistent ordering of arguments inside Lscope API

OTHERS:
- Auxiliary function append_block_of_env_to_block
- Squash pattern matching of mk_storing_loops
- No Interval.infer in to_exp
- Refactoring of pre_from_label
- pi_beta_j with fold_left
- No superfluous env for sizes_and_shifts_from_quantifs
- More efficient accumulator for computing size
- Squash pattern matching of sizes_and_shifts_from_quantifs
- No superfluous option for get_lscope_var
- Better definition of effective_lscope_from_pred_or_term
- Using List.find for defining get_lscope_var
- Do not export get_lscope_var
- Lscope.empty () -> Lscope.empty

- 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
