Update the LDAP client code to make it possible to specify certain controls by
a more user-friendly name instead of the numeric OID when using the "-J" or
"--control" option.  These changes include:

- "accountusable" or "accountusability" may be used to specify the account
  usable request control
- "authzid" or "authorizationidentity" may be used to specify the authorization
  identity request control
- "noop" or "no-op" may be used to specify the LDAP no-op control
- "subentries" may be used to specify the LDAP subentries request control
- "managedsait" may be used to specify the manage DSA IT control
- "pwpolicy" or "password policy" may be used to specify the password policy
  request control
- "subtreedelete" or "treedelete" may be used to specify the subtree delete
  control
