1) Restricted ALTER/DROP permissions to the object owners only. Now this applies to domains, charsets, collations, generators and exceptions. This fixes CORE-304: Metadata security hole - any user can alter/drop generators and exceptions.
...
2) Opened the gates to implement the standard USAGE privilege (CORE-2884). SQL support and validation logic are still to be developed.
3) Added the grant option to the owner permissions for packages, procedures and functions.
4) Misc cleanup and refactoring.

Return explicit sign of active transaction from VIO_get_current() - it makes logic more clear in check_duplicates() and allows to clear transient lock error from status vector and not propagate up to the callers.

Reworked the garbage collector thread:
...
- a single try-catch block looks better
- cross-helping between GC and CW/CR threads is agreed to be a bad idea
- replaced ATT_disable_gc_notify with a check inside notify_garbage_collector()
- made the logic more straightforward
Careful review would be appreciated.
