Set encoding and blooms on meta as default. Also shutdown access to the
initial meta schema creating method; get from TableDescriptors if you
need access to schema or edit it as you would any other table if you
want to edit it.

Decouple the HBase internals such that someone can implement
their own SASL-based authentication mechanism and plug it into
HBase RegionServers/Masters.
Comes with a design doc in dev-support/design-docs and an example in
hbase-examples known as "Shade" which uses a flat-password file
for authenticating users.

The current process for an operator, after fixing holes in meta, is to
manually disable and enable the whole table. Let's try to avoid
bringing the whole table offline if we can. Have the master attempt to
queue up assignment procedures for any new regions it creates.

The cleanupBulkLoad method is only called for the first Region in the
table which was being bulk loaded into. This means that potentially N-1
other RegionServers (where N is the number of RegionServers) will leak
one FileSystem object into the FileSystem cache which will never be
cleaned up. We need to do this clean-up as a part of secureBulkLoadHFiles
otherwise we cannot guarantee that heap usage won't grow unbounded.

Make it so hbase:meta can be altered. TableState for hbase:meta
was hardcoded ENABLED. Make it dynamic. State is now kept in
current active Master. It is transient so falls back to default
if Master crashes. Add to registry a getMetaTableState
which reads mirrored state from zookeeper (NOT from Master and
defaults ENABLED if no implementation or error fetching state).
hbase:meta schema will be bootstrapped from the filesystem.
Changes to filesystem schema are atomic so we should be ok if
Master fails mid-edit (TBD). Undoes a bunch of guards that
prevented our being able to edit hbase:meta.
TODO: Tests, more clarity around hbase:meta table state, and undoing
references to hard-coded hbase:meta regioninfo.

Change its behavior so it will only look in hbase:meta
if the call to the super class turns up zero references.
Only then will it search hbase:meta for references to
'Unknown Servers'. Normal operation where we read Master
context is usual and sufficient. The scan of hbase:meta
is only for case where Master state has been corrupted
and we need to clear out 'Unknown Servers'.
