Add new files in release_docs to MANIFEST. Cimmit changes to Makefile.in(s) and H5PL.c that resulted from running autogen.sh. Merge pull request #407 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:hdf5_1_10_1 to hdf5_1_10_1 Change copyright headers to replace url referring to file to be removed and replace it with new url for COPYING file.

* Checkin of fix for CGNS bugmainzer2017-04-061-1/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (https://jira.hdfgroup.org/browse/HDFFV-10055). Briefly, in H5C_collective_write() in H5Cmpio.c, the metadata cache attempts to perform a collective write of metadata cache entries. This worked fine as long as all processes had at least one entry to write. However, when the process has no entries, the function tries to participate in the collective write by calling MPI_File_set_view(), MPI_File_write_all() and then MPI_File_set_view() again, to match the calls in H5FD_mpio_write(). After pull request 183, the CGNS test benchmark_hdf5 started failing. On investigation, I determined that the failure occurred in the first call to MPI_File_set_view() in the "no data to write" path through H5C_collective_write(). Note that pull request 183 did not create the problem, it only exposed it. The bug can be observed after pull request 182 if one executes the CGNS progam src/ptests/benchmark_hdf5 with 90 processes. The problem appears to have been that the calls to MPI_File_set_view() in H5C_collective_write() and H5FD_mpio_write() were using different values for the info parameter. I patched the problem by adding a MPI specific VFD call allowing me to get the MPI_Info used in H5FD_mpio_write() for use in MPI_File_set_view() calls in H5C_collective_write(). Tested serial & parallel, debug & production on Jelly.
* Omnibus checkin for several relatively minor modifications:mainzer2017-03-281-1/+3
| | | | | | | | | | | | | | | | | | | | 1) Added code test/page_buffer.c to verify that page buffering is disabled in parallel builds. 2) Added code to test/cache_image.c to verify correct interaction between evict on close and cache image -- in particular management of a file containing a cache image containing dirty metadata that has been opened R/O. Also fix for the bug exposed. 3) Added code to testpar/t_cache_image.c to verify expected procedure for reading cache images, and also supporting stats collection code needed for the test. 4) Repair of an overactive sanity check in H5C__reconstruct_cache_contents(). 5) Other minor tidies in passing. Tested serial and parallel, debug and production on Jelly.
