First: Sorry for this monster patch, I find no way to split it semanticaly

without introducing unneeded diffs.

Fix the bug where results are not properly separated by local roles when
mutilple worklists exist for the same role (causing worklists to appear as
containing too many documents).
Implies:
   Expand security at groupWorklistListByCondition level.
   Handle each security-related catalog column as a distinct worklist
   combination of worklist parameters. (for example, a worklists with local
   roles Owner and Assignor would require a match on both the "owner" and the
   "security_uid" catalog columns).
   Implies:
     Each security criterion must be used once positively and negatively
     thereafter to prevent a line from matching multiple queries.
     Implies:
       Implement ExclusionList and ExclusionTuple, two dummy classes to
       contain criterions to be negated in queries (as in 'NOT IN ...' instead
       of 'IN ...'), and use them in groupWorklistListByCondition and
       generateNestedQuery.
     Security criterions must be part of the match when summing up all results
     Implies:
       Sums must be done across multiple loops in
       worklist_list_grouped_by_condition.
       Separate metadata from worklist grouping by criterion, so that suming-
       up worklists results can be done in one run.
       Implies:
         workflow_worklist_key is now computed early in
         groupWorklistListByCondition.
         generateActionList now takes a non-grouped metadata dict and is only
         run once.
Update groupWorklistListByCondition docstring.
Remove unneeded checks for SECURITY_PARAMETER_ID, WORKLIST_METADATA_KEY and
INTERNAL_CRITERION_KEY_LIST.
Remove now unused INTERNAL_CRITERION_KEY_LIST global.
Remove unused generateQueryFromTuple method.
Remove unused securityQueryHook local method, instead
getSecurityUidListAndRoleColumnDict is passed at groupWorklistListByCondition
level.
Finally, re-enable worklist optimisation monkey patch.
