This commit changes the way that orphan blocks are identified by adding a new boolean return value on ProcessBlock and removing the notification for NTOrphanBlock. This allows the calling code to identify orphan blocks immediately instead of having to setup a seperate callback handler and implementing some type of state tracking. This, in turn, allows cleaner code for handling them. In addition, the tests have been updated for the new function signature and also now check that each block is or is not an orphan as expected which makes the tests more robust. ok @jrick
