696173c284 Add esnprintf that prints to the given buffer, observing the given 
buffer size, using vsnprintf(3), but exits with err(3)/errx(3) if the

de18e8c95a Make await_signal() await any signal instead of just SIGINT. Add a 
(commented out) private version of strsignal(3), just in case we need
one on some platform.

1818420acd In await_signal(), print a less alarming message when exiting in normal

c8f533cfc3 Merge all of my changes from merge-back-to-feature-vfd_swmr-attempt-1, 
including the merge of `hdffv/hdf5/develop`, back to the branch that Vailin and
I share.

Now I need to put this branch on a fork with a less confusing name than
vchoi_fork!

ce2748f011 (A) Fixes for the assertion failures described in issue #2 (see John Mainzer's last checkin message): 
--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
