Improve open-to-close semantics

This bugfix improves xrootd-hdfs's open-to-close semantics. We now synchronize before close, which appears to help force the namenode to update the metadata as soon as the file handle is closed.

Further, if the parsing checksums fails (for example, if the checksum writing is incomplete when the checksum request is done), then we now will retry with a new checksum calculation.

Fix checksums when N2N is used

This release fixes a bug where, when name translation was in use, XrdHdfs did not respond correctly to checksum requests.

Fix segfault in checksum printing

This release includes a single bugfix of a segfault when converting checksum bytes to a human-readable format.

Packaging Fixes Release

This release solely contains packaging fixes in order to support both OSG the 3.3 and 3.4 downstream release series (they differ by major HDFS versions, which subtly changes some RPM names).
