into the image and running 'pkg install' from there, use 'pkg fetch' to download packages into a temporary location and then 'pkg add' to install them into the image. This simplifies the code by avoiding the need to copy /etc/resolv.conf into the image and then delete it later, and makes it possible to cross build (e.g., to create an amd64 image when running on i386 hardware; or in the future for building disk images for embedded platforms). Because pkg was implicitly installed when VM_EXTRA_PACKAGES was non-empty, add it to VM_EXTRA_PACKAGES in azure.conf and openstack.conf to maintain the current behaviour. By default repo-FreeBSD.sqlite is copied into the image, (a) to match previous behaviour, where the file would be downloaded by the chrooted pkg invocation; and (b) because it may be useful for testing purposes, e.g., to see why a package didn't get installed. Because this file is large (46 MB) and not likely to be useful in -RELEASE images which are being launched into Clouds several months later, it can be disabled by setting NOREPOSQLITE. As far as I know this commit does not change the disk images produced in any filesystem-visible way.
