pkg_install: Fix and speed up "pkg_admin rebuild-tree". In the pkg_admin front end, instead of adding +REQUIRED_BY entries as they are found, which previously led to duplicate entries, cache the results and write out the files at the end. Underneath, add a caching version of iterate_pkg_db() that avoids the same pkgdb directory lookup for every installed package, but is only suitable for reads. Also add a cache for best_match lookups to avoid expensive matches each time. For all caches, use a simple hashing function to improve lookup performance. In summary, as well as fixing +REQUIRED_BY files, these patches reduce the wall/user/system time of "pkg_admin rebuild-tree" on a system with 12,762 packages installed down from 13m52s/11m20s/2m32s to just 1m4s/1m3s/0m1s.
