Extend apt build-dep pkg/release to switch dep as needed

2018-05-11T15:58:46Z

apt install pkg/release follows versioned dependencies in the candidate switching if the current candidate does not satisfy the dependency, so for uniformity the same should be supported in build-dep.

fix various typos reported by spellintian

Most of them in (old) code comments. The two instances of user visible string changes the po files of the manpages are fixed up as well. Gbp-Dch: Ignore Reported-By: spellintian

avoid building dependency tree in 'source' command

2016-02-03T13:56:49Z

We don't need the dependencies for obvious reasons and we don't need the candidate version either, so building a pkgDepCache is wasted effort, which we can stop doing now that build-dep cleared the path.

use pkgCache::VS instead of pkgDepCache::VS()

The later just calls the earlier, but the later needs the fullblown dependency cache to be initialized, which is a very costly operation and isn't done anymore that early in the run as we would need to throw away and rebuild it again after we got all the information about source pkgs. As we end up with a nullptr for the pkgDepCache, we use a slightly longer calling convention to make sure that we use the pkgCache directly, avoiding nullptr induced segfaults and costly operations.
