Dana Robinson 2266ee56c3 Fixes minor issues in various virtual file drivers
- HDFS VFD files now ignored in the Autotools when the HDFS VFD is not
  being built.
- All VFD init code uses idiomatic H5I_INVALID_HID instead of -1
  or FAIL.
- The HDFS VFD now includes H5FDdrvr_module.h in the right place.
- The HDFS tests in test/hdfs.c no longer pass NULL to VERIFY macros, which
  raised warnings.
- Minor tweaks to fix const, unused variables, etc. warnings in
  several VFDs.
