3436691899 Refactored get_role_access into a generic traverse function. 
The function now performs a DEPTH FIRST SEARCH on the role graph.

At various key points: on_start, on_open, on_cycle, on_finish,
the function calls one of the corresponding functions passed as parameters.

766ae81aa4 Fixed bug that caused rename user test case to fail. 
The bug was caused by not renaming the role if it was previously
modified by the handle_grant_struct(ROLE_ACL,...) call.

The same function used find_acl_role and would search for the already
renamed role when it handled ROLES_MAPPINGS_HASH. This caused it to not rename
the role/user correctly.

ce4851c3d0 Reworked the implementation of create role and drop role. 
Also fixed issue with drop role not clearing internal memory entry
for that role. The issue was due to a condition introduced in handle_grant_data

Updated testsuite to also check the possible error conditions.

2755c342e6 Added extra comments to explain the ACL_USER_BASE flags usage, as well as fix an issue with get_role_access.
