@PolicyDirection was hidden API defined in IpSecManager and
mainline module IPsec(IKE) needs to depend on it.

To remove this hidden API dependency, this commit:
- Moves definition of @PolicyDirection to a separate class
- Creates sharing filegroup framework-ike-shared-srcs for mainline
  IKE and include PolicyDirection.java

* changes:
  Make LinkPropertiesTest pass, and fix an NPE.
  Add the DHCP server address to LinkProperties.

aosp/973686 added the DHCP server address to LinkProperties, but
it did not have any tests, and would throw NPE when parceling a
LinkProperties that did not have a DHCP server.

Add tests and fix the bug.
