* HADOOP-18671. Add recoverLease(), setSafeMode(), isFileClosed() as interfaces to hadoop-common (#5553)
The HDFS lease APIs have been replicated as interfaces in hadoop-common so other filesystems can
also implement them. Applications which use the leasing APIs should migrate to the new
interface where possible.

Changes method name of RPC.Builder#setnumReaders to setNumReaders()
The original method is still there, just marked deprecated.
It is the one which should be used when working with older branches.
