Merge pull request #593 in HDFFV/hdf5 from hdf5_1_8_19 to 1.8/masterhdf5-1_8_19

* commit 'c15238a38fdb3692466bc1218de4c5aeb420fdcc': (153 commits)
  Commit changes to release version strings in README.txt and RELEASE.txt from release.
  Put back link targets for dynamically loaded libraries in Makefile.ams that avoid linking with libhdf5 dependencies.  Some configurations failed unnecessarily to find and link with lz and lsz when these targets were removed.
  Update URL for obtaining source inINSTALL file.
  Disable building of libdynlib* dynamically loaded plugin test libraries on CYGWIN. Added known problem entry to RELEASE.txt. Set version for 1.8.19 release. Barbara updated contents of README.txt file.
  Moved libdynlib* plugin test libraries to noist_LT_LIBRARIES with added flag '-rpath /nowhere' to stop them being installed while keeping them from linking with libhdf5, etc. Incremented version to 1.8.19-pre1 and ran bin/release to create tar and zip files for testing.
  HDF5 1.8.19-pre1 released.
  Add RELEASE.txt entry for H5Dget_chunk_size.
  Remove test entries
  Ran bin/reconfigure after so number change.
  Update hl lib .so numbers:  new function was added. Update RELEASE.txt:  move H5DOread_chunks entry to new features, clarify entry for HDFFV-10051.
  Updated notes for test fixes and added bug fix for h5diff help text.
  Update h5vers and release scripts for 1.8.19 branch, set version to 1.8.19-pre1.
  Make script name consistent across product versions
  Update version to 1.8.19-pre1.
  Propagate .so number changes to Makefile.ins with bin/reconfigure.
  Add toolset option
  Update so version numbers according to the interface compatibility report.
  Update supported Platforms section. Remove empty sub-sections of New Features and Bugs Fixed sections.
  Add entries for HDFFV-10051 and HDFFV-9934 to RELEASE.txt.
  Correct spelling

+ *        Failure:    0
