* commit '5988b1d2f6376e6b1dbca3c0495108954759c4c0':
Modifications to paged aggregation: (1) Fail file create when page buffering is enabled for parallel (2) Fail file create for multi/split drivers when paged aggregation strategy is used or persisting free-space (3) Define a minimum size of 512 for file space page size (4) Fixes to src/H5MF.c and tidy up unused coding (5) Changes to test directory: --cache.c, cache_api.c, dsets.c, 1 test in fheap.c are modified to test with paged aggregation enabled --Fixes to mf.c, tfile.c, stab.c, cache_tagging.c --tpage_buffer.c: skip test when parallel skip test for mult/spilt drivers fixes due to minimum file space page size of 512 Tested on emu, moohan, mayll, playtypus, ostrich, kituo, kite, quail, osx1010test Note that some tests fail when --enable-direct-vfd. These failures occur before this checkin. There are simil r test failures in "develop" branch when --enable-direct-vfd.
