ISPN-3239 LevelDB Cache Store to support JNI with proper fallback to
pure Java implementation
ISPN-3217 Rebalance doesn't store data into cache store

In non-tx mode, if the originator of a put command is an owner, it will
only write the entry when the command is forwarded back to it by the
primary owner. But this rule shouldn't apply to state transfer puts,
which use the CACHE_MODE_LOCAL and SKIP_OWNERSHIP_CHECK flags.

DistCacheStoreInterceptor is now used for replicated caches as well.
ISPN-2753 Drop Staxmapper dependency from LevelDB cachestore
ISPN-3263 Add a 5.3 parser and XSD to the LevelDB cachestore

ISPN-3243 Memcached flush_all should not have flags

ISPN-3268 Move Equivalence API classes to their own package
ISPN-3192 Concurrent TreeCache.move() calls with the same destination lose data

Causes intermittent failures in NodeMoveAPIPessimisticTest.
Lock the destination node and the parent of the source node the first time
they are read (in pessimistic mode).
ISPN-3268 test fixed after moving the Equivalence API classes to their own package
