[mainzer@jelly test]$
(1) Assertion failure in the vfd_swmr test
(2) Reader error in the vfd swmr concurrent tests
Also fixes for:
(a) Use H5MV_alloc() to allocate space for md_pages_reserved when creating the metadata file in H5F__vfd_swmr_init()
(b) Remove a multi-page (when vfd_swmr_writer is true) from the page buffer in H5MF_xfree()
--src/H5PB.c: checks for size >= page size
--src/H5MF.c: disable/enable page buffering in H5MF_tidy_self_referential_fsm_hack()
--src/H5MFsection.c: call H5PB_remove_entry() for both raw/metadata pages in H5MF__sect_small_merge()
(B) Port and modify existing concurrent swmr tests to VFD SWMR. Also modify the following:
--remove flushes from VFD SWMR writer tests
--set Nreaders to 0 in test/testvfdswmr.sh.in to test for writers only
