Issue #2000 - Stop using deprecated ext/hash_map.

This has been long deprecated in favor of std::unsorted_map. Since all platforms
are using modern compilers now it should not be a problem to switch over to
std::unsorted_map in the single place hash_map is used. This allows us to build
on platforms which have removed hash_map such as FreeBSD.
