pkgdb: Tolerate missing password file

Also don't ask the user for password. If the password is not in the
file, there's no password.

pkgdb: Remove the word 'Error'

It looks worse than it is.

catalog-release-to-disk: New catalog generation utility

New features compared to the old solution:

- Runs multiple REST queries in parallel
- Only links and/or unlinks pkg files on disk when necessary
- Only generates new index (catalog/description) files when necessary

This patch removes the old code to avoid confusion.
