[PATCH] hashmap: address ThreadSanitizer concerns

From: Jeff Hostetler <redacted>

This is to address concerns raised by ThreadSanitizer on the
mailing list about threaded unprotected R/W access to map.size with my previous
"disallow rehash" change (0607e10009ee4e37cb49b4cec8d28a9dda1656a4).

See:

TODO  This version contains methods to disable item counting and automatic
rehashing independently.  Since the latter is implicit with the former, we
could get by with just the one, but I thought we could discuss it since it
does provide a little extra clarity of intent.
