* Respect INDEXDIR after fetching INDEX (Andrew Pantyukhin <sat@FreeBSD.org>)
* Add --batch opition.
* Add --without-env-upgrade option.
* Remove -DPACKAGE_BUILDING (it was in fetch-only mode) because it's only
for build cluster, not users. (Pointed out by kris@FreeBSD.org)
* Add detection of stale lock files. They can stay if one of tools suddenly
terminated.
* Improve pkgdb -F - respect OPTIONS and pkgtools.conf settings.
