These functions make it easier to possible to use
`org.apache.hadoop.hbase.client.Table.CheckAndMutateBuilder#timeRange`
with more interesting ranges, without being forced to use the
deprecated constructors.

Makes MergeTableRegionsProcedure do more than just two regions at a
time. Compatible as MTRP was done considering one day it'd do more than
two at a time.
Changes hardcoded assumption that merge parent regions are named
mergeA and mergeB in a column on the resultant region. Instead
can have N columns on the merged region, one for each parent
merged. Column qualifiers all being with 'merge'.
Most of code below is undoing the assumption that there are two
parents on a merge only.
This is a first cut at this patch. Implements hold fixing only
currently.
Add a fixMeta method to Hbck Interface.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java
Bug fix. If hole is on end of last table, I wasn't seeing it.
A hbase-server/src/main/java/org/apache/hadoop/hbase/master/MetaFixer.java
Add a general meta fixer class. Explains up top why this stuff doesn't
belong inside MetaTableAccessor.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java
Break out the filesystem messing so don't have to copy it nor do more
than is needed doing fixup for Region holes.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionFileSystem.java
Change behavious slightly. If directory exists, don't fail as we did
but try and keep going and create .regioninfo file if missing (or
overwrite if in place). This should make it idempotent. Can rerun
command. Lets see if any repercussions in test suite.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMetaFixer.java
Add test.

Refactor of CatalogJanitor so it generates a
Report on the state of hbase:meta when it runs. Also
refactor so CJ runs even if RIT (previous it would
punt on running if RIT) so it can generate a 'Report'
on the interval regardless. If RIT, it just doesn't
go on to do the merge/split GC as it used to.
If report finds an issue, dump as a WARN message
to the master log.
Follow-on is to make the Report actionable/available
for the Master to pull when it goes to draw the hbck
UI page (could also consider shipping the Report as
part of ClusterMetrics?)
Adds new, fatter Visitor to CJ, one that generates
Report on each run keeping around more findings as
it runs.
Moved some methods around so class reads better;
previous methods were randomly ordered in the class.
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Make a few handy methods public.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RegionInfo.java
Add utility as defaults on the Inteface; i.e. is this the first region
in table, is it last, does a passed region come next, or does passed
region overlap this region (added tests for this new stuff).
M hbase-common/src/main/java/org/apache/hadoop/hbase/util/Bytes.java
Bugfix... handle case where buffer passed is null.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java
Lots of change, reorg., but mostly adding consistency checking
to the visitor used scanning hbase:meta on a period and the
generation of a Report on what the scan has found traversing
hbase:meta. Added a main so could try the CatalogJanitor against
a running cluster.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestCatalogJanitorCluster.java
Fat ugly test for CatalogJanitor consistency checking.
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestHRegionInfo.java
Add tests for new functionality in RI.
M hbase-shell/src/main/ruby/hbase/table.rb
Bug fix for case where meta has a null regioninfo; scan was aborting.
