usage - necessary to use larger types for interop with a certain client
that would expect the assertion (attr:1.2.840.113556.1.4.803:=2147483648)

There are probably better / more portable solutions; review appreciated.

  moved labeledURI into system schema
  attribute types that inherit from labeledURI may be used in dynamic

	access to attr=foo val.regex=bar.*

is changed to mean attrs="*"

 - the consumer slapd did not terminate when the provider is alive
 - use a timeout in ldap_result() of syncrepl.c
