Correct handling of 32-bit integer attributes in SAMBA 4

Browse Source 
- LDB handles now all 32-bit integer attributes correctly (also with overflows)
  according to the schema
- LDAP backends handle the attributes "groupType", "userAccountControl" and
  "sAMAccountType" correctly. This handling doesn't yet use the schema but
  the conversion file "simple_ldap.map.c" which contains them hardcoded.
  Did also a refactoring of the conversion function there.
- Bug #6136 should be gone
