Adds region state check on hbck2 assigns/unassigns. Returns pid of -1
if in inappropriate state with logging explaination which suggests
passing override if operator wants to assign/unassign anyways. Here
is an example of what happens now if hbck2 tries an unassign and
Region already unassigned:

Previous it would just create the unassign anyways. Now must pass override
to queue the procedure regardless. Safer.

javadoc on assigns/unassigns. Minor refactor in assigns/unassigns to cater to
case where procedure may come back null (if override not set and fails state checks).

checkstyle cleanups.
Clarifying javadoc on how there is no state checking when bulk assigns creating/enabling
tables.
createOneAssignProcedure and createOneUnassignProcedure now handle exceptions which now
can be thrown if no override and region state is not appropriate.
Aggregation of createAssignProcedure and createUnassignProcedure instances adding in
region state check invoked if override is NOT set.

Change to setProcedure so it returns passed proc as result instead of void

Allow specifying base WALEntry filter on construction of
ReplicationSource. Add means of being able to filter WALs by name.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSource.java
Add constructor that allows passing a predicate for filtering *in* WALs
and a list of filters for filtering *out* WALEntries. The latter was
hardcoded to filter out system-table WALEntries. The former did not
exist but we'll need it if Replication takes in more than just the
default Provider.
