The vm_extra_pre_umount function in vmimage.subr served two purposes: It removed /etc/resolv.conf and /qemu (if cross-building), and it provided a function for cloudware to override in order to make cloud specific changes to the filesystem before constructing a disk image. This resulted in a number of bugs: 1. When cross-building, the emulator binary was left as /qemu in the Azure, GCE, Openstack and Vagrant images. 2. The build host's resolv.conf was left as /etc/resolv.conf in the basic-ci and basic-cloudinit images. 3. When building GCE images, a Google-specific resolv.conf file was constructed, and then deleted before the disk image was created. Move the bits needed for running code inside a VM staging directory from vm_install_base into a new vm_emulation_setup routine, and move the corresponding cleanup bits from vm_extra_pre_umount to a new vm_emulation_cleanup routine. Remove the /qemu and /etc/resolv.conf cleanups from the cloudware configuration files (where they exist) since we will now be running vm_emulation_cleanup to remove those even when vm_extra_pre_umount has been overridden. Override vm_emulation_cleanup in gce.conf since in that one case (and *only* that one case) we don't want to clean up resolv.conf (since it was constructed for the VM image rather than copied from the host). releng/14.1 candidate.
