classical producer/consumer synchronization scheme
* xbt_dynar_new_sync() creates a synchronized dynar. All access
(using the classical functions will get serialized) [Mt]
+ * Make dictionary internal table dynamic. No need to specify its size
+ anymore; functions xbt_dict_new_ext() and xbt_dict_hashsize_set()
+ thus dropped. [Mt].
+ * Make sure the log channels are organized as a tree under windows
+ (because of ANSI C compatibility issue, any channel were child of
+ root directly) [Mt].
SURF:
* Cleaned many thing in surf and fixed a few bugs [AL].
