Minor bugfixes from initial v2.0 deploys

This bugfix release corrects directory creation logic which was noticed when testing v2.0 at Caltech.

Mostly minor, but everyone will appreciate it! Enjoy!

Xrootd-HDFS Improved Write Support

Historically, Xrootd-HDFS has been used as a mechanism to provide data access -- that is, reading data remotely from sites.

However, as Xrootd grows in its capabilities (particularly, integrity checking and HTTP/WebDAV support), we've been getting requests to fill in the missing pieces of the API for writing.

With this release, one can:

• Make directories.
• Remove files and directories.
• Write files larger than 2GB.
• Perform chmod against a remote server.

Overall, this brings xrootd-hdfs closer to exposing the full set of underlying filesystem capabilities.

Enjoy!

Minor bugfix in listing directories

This release fixes a minor bug for reporting error codes when listing directories fails. Previously, it was possible for the error state to leak between calls to libhdfs.

Performance Improvements

This bugfix release tweaks the runtime environment to allow HDFS to load its native libraries.

The native libraries contain heavily-optimized code for performance critical sections (such as checksum calculations); without them, the libhdfs library will fall back to the slower Java equivalents when used from xrootd-hdfs.

EL7 bugfix release

This bugfix release features minor fixes for compilation on the EL7 platform (as well as accompanying packaging fixes from OSG).
