string_split_shared and string_free_split_shared)

    core: add shared strings to reduce memory usage
    
    Shared strings are stored in a hashtable with pointer for keys (values are 
not
    used).
    
    The key has a reference count + the string.
    The initial reference count is set to 1 and is incremented each time the 
same
    string is asked.
    
    When removing a shared string, the reference count is decremented.
    If it becomes 0, then the shared string is removed from the hashtable (and 
then
    the string is really destroyed).
