    Merge pull request #2636 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:HDFFV-11000-update-testh5cc.sh.in-for-version to develop

    * commit '5c0bd670d6e9919c463fbc05de99e2ba55b0761e':
      Add tests for all version to H5_NO_DEPRECATED_SYMBOLS section and to section for current version, with and without default API version flags.
      HDFFV-11000:  update-testh5cc.sh.in to test sample versioned functions in HDF5 1.10, 1.12 and develop.

* Update configure and Makefile.ins after bin/reconfigure.

* Fix MANIFEST

* Fix HDFFV-10591

Description:
    h52gif produced a segfault when a buffer overflow occurred because
    the data size was corrupted and became very large.  This commit added
    a check on the data size against the buffer size to prevent the segfault.
    It also added error reporting to h52gif to display an error message
    instead of silently exiting when the failure occurred.
Platforms tested:
    Linux/64 (jelly)

* Snapshot 1.8.22-snap9. Update version to 1.8.22-snap10.

(2) Test to verify the fix when doing multiple threads
(3) Update MANIFEST
(4) Add new test to Cmake

* Switch bison and flex update of LT files from bin/genltanalyse to
bin/genparser, and from automatically updating the LT files whenever
reconfigure is run to running only on man<F12>ual command.

* Update hl/sr/H5LT files.
Add bin/genparser to MANIFEST; remove bin/genltanalyze.

* Fix to the merge of PR #2708 for HDFFV-11080 to the 1.8 branch.

* Fix HDFFV-11120 and HDFFV-11121 (CVE-2018-13870 and CVE-2018-13869)

Description:
    When a buffer overflow occurred because a name length was corrupted
    and became very large, h5dump produced a segfault on one file and a
    memcpy parameter overlap on another file.  This commit added checks
    that detect a read pass the end of the buffer to prevent these error
    conditions.

* Reverts lock/unlock callback signature to 1.8.21 version (#254)

* Reverts lock/unlock callback signature to 1.8.21 version

This callback is unused in 1.8. The ros3 and hdfs VFDs are the only VFDs
that have the lock callback implemented and that is just as no-op stubs.
These stubs were removed so the callbacks are now NULL pointers, like
the other VFDs in 1.8.
