/**
* xmlCanonicPath:
* @path: the resource locator in a filesystem notation
*
* Constructs a canonic path from the specified path.
*
* Returns a new canonic path, or a duplicate of the path parameter if the
* construction fails. The caller is responsible for freeing the memory occupied
* by the returned string. If there is insufficient memory available, or the
* argument is NULL, the function returns NULL.
