Adds a row/column filter interface and two implementations: A pager and a
row/column-value regex filter.

On shutdown, region servers and masters were just cancelling leases
without letting 'lease expired' code run -- code to clean up
outstanding locks in region server. Outstanding read locks were
getting in the way of region server getting necessary write locks
needed for the shutdown process. Also, cleaned up messaging around
shutdown so its clean -- no timeout messages as region servers try
to talk to a master that has already shutdown -- even when region
servers take their time going down.
M src/contrib/hbase/conf/hbase-default.xml
Make region server timeout 30 seconds instead of 3 minutes.
Clients retry anyways. Make so its likely region servers report
in their shutdown message before their lease expires on master.
M src/contrib/hbase/src/java/org/apache/hadoop/hbase/Leases.java
(closeAfterLeasesExpire): Added.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
Added comments.
(stop): Converted from public to default access (master shuts
down regionservers).
(run): Use leases.closeAfterLeasesExpire instead of leases.close.
Changed log of main thread exit from DEBUG to INFO.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMaster.java
(letRegionsServersShutdown): Add better explaination of shutdown
process to method doc. Changed timeout waits from
hbase.regionserver.msginterval to threadWakeFrequency.
(regionServerReport): If closing, we used to immediately respond
to region server with a MSG_REGIONSERVER_STOP. This meant that
we avoided handling of the region servers MSG_REPORT_EXITING sent
on shutdown so region servers had no chance to cancel their lease
in the master. Reordered. Moved sending of MSG_REGIONSERVER_STOP
to after handling of MSG_REPORT_EXITING. Also, in handling of
MSG_REGIONSERER_STOP removed cancelling of leases. Let leases
expire normally (or get cancelled when the region server comes in
with MSG_RPORT_EXITING).
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMsg.java
(MSG_REGIONSERVER_STOP_IN_ARRAY): Added.

* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HMemcache.java
(findFirstRow): Change compare from startsWith -- looking for
an 'exact' match -- to instead use compareTo and if >= 0, then
we are at first key.
* src/contrib/hbase/src/java/org/apache/hadoop/hbase/HRegionServer.java
Add logging of problematic directory if server won't start because
log file exists.

so that region servers are assigned the regions have a log to apply edits from. Enhance fail over
capabilities.
For all the files modified, clean up javadoc, class method and field visibility.
