Merge pull request #1590 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:1.10/master to 1.10/masterhdf5-1_10_5
* commit '6819c11508b0610f222fe3bfe8a19f637bf4319c': (154 commits) CMake needs a tar.gz examples file for windows, too. Correct file permissions on README.txt. Address merge anomalies and incorrect file permissions. Update release date in README.txt and RELEASE.txt. Revisions to Platforms tested. Updated LT_VERS_AGE in config/lt_vers.am due to reinstatement of previously removed symbols, then ran autogen.sh to propagate so number changes and H5E_LOGFAIL_g addition to files checked in on release branch. Updated H5err.txt to replace a global variable that was removed during the metadata cache logging changes (to maintain binary compatibility). HDFFV-10552,10686 restore H5O_*1 functions Minor fix in h5str_sprintf for NULL region references Add new files to MANIFEST. Update so version numbers. fix 2 typos. Update RELEASE.txt for TRILABS-34 and remove unused sections. Add script for building HDF5 with CMake on HPC machines that use sbatch. Add README file for inclusion in CMake-hdf5-<version>.tar.gz file. Add updated README_HPC file with cross compile instructions. set version to 1.10.5-pre1. Change default build mode to production. Merge pull request #1560 in HDFFV/hdf5 from hdf5-1-10-documentation-only to hdf5_1_10_5 Update HISTORY-1_10.txt and RELEASE.txt files. Modify RELEASE.txt in response to PR comments Check in files generated by autogen.sh for hdf5_1_10_5 release branch. Check in files generated by autogen.sh for hdf5_1_10_5 release branch. 2019/02/16.
