+2004-11-03 Arnaud Legrand
+  - Rename every gras_* function that was in xbt/ to its xbt_
+    counterpart.
+  - Add a heap and a doubly-linked list to xbt
+  - Added a dichotomy to the dictionnaries. make check works as well before
+    so I assume that the patch is correct. I do not know however if things
+    run effectively faster than before now. :)

+  - Introduction of the remote errors. 
+    They are the result of a RMI/RPC on the remote machine.
+    ErrCodes being scalar values, you can't get the host on which those
+    errors did happen. Extending the error mecanism as in Gnome is possible.
+    No idea yet whether it is a good idea.

+  - Interface revolution: the Starred Structure Eradication.
+    I used to do typedef struct {} toto_t; and then handle *toto_t.
+    Arnaud (and Oli) didn't like it, and I surrendered. Now, you have:
+      - ???_t is a valid type (builded with typedef)
+      - s_toto_t is a structure (access to fields with .)
+      - s_toto   is a structure needing 'struct' keyword to be used
+      - e_toto_t is an enum
+      -   toto_t is an 'object' (struct*)
+    Exemple:
+      typedef struct s_toto {} s_toto_t, *toto_t;
+      typedef enum {} e_toto_t;
+    Moreover, only toto_t (and e_toto_t) are public. The rest (mainly
+     s_toto_t) is private.
+    
+  - While I was at it, all gras_<obj>_free() functions want a gras_<obj>_t*
+    so that it can set the variable to NULL. It was so for dicts and sets,
+    it changed for dynars.
+    
+  - Fix a bunch of memleaks in dict_remove
+  - Fix a bug in sg/server_socket opening: it failed all the time.
+

+  - Speed up dynar lookup operation a bit.
+  
+    gras_dynar_get is dead. 
+    
+    Now, you can choose between gras_dynar_get_cpy (the old gras_dynar_get
+    but should be avoided for efficiency reasons) and gras_dynar_get_ptr
+    (which gives you the address of the stored data).
+    
+    gras_dynar_get_as is an helpful macro which allows you to retrieve a
+    copy of the data using an affectation to do the job and not a memcpy.
+    
+    int toto = gras_dynar_get_as(dyn,0,int); rewrites itself to
+    int toto = *(int*)gras_dynar_get_ptr(dyn,0);
+    
+    It does not really speedup the dynar test because they are
+    setting elements all the time (and look them seldom). But the dict does
+    far more lookup than setting.
+
+    So, this brings the dict_crash test from ~33s to ~25s (200000 elms).

   - Allow to (en/dis)able the cycle detection at run time.
   
     Whether we should check for cycle or not is now a property of each
