These tests document the relative precedence of the stable, bottle,
devel, and head specifications, and the conditions that can influence
which is selected (e.g. command-line flags).
The initializer for Formula does a number of validations, but it does
them in a weird order, and some attributes aren't validated under
certain circumstances. This became even more of a mess when most
software package attributes were moved into the SoftwareSpec class.
This commit removes the last vestiges of storing these attributes as
instance variables. In particular, it eliminates #set_instance_variable
and #validate_variable, replacing them with methods that operate on
SoftwareSpec instances, and generate more useful errors.
Doing these validations unconditionally in the initializer means we bail
out much earlier if the formula has invalid attributes or is not fully
specified, and no longer need to validate in #prefix.
Technically we don't need to validate in #brew either, but we continue
to do so anyway as a safety measure, and because we cannot enforce calls
to super in subclasses.
brew versions is hardcoded to cd to HOMEBREW_REPOSITORY before running
git, and as such fails to report previous versions for any formulae
from a tapped repository.
Add two new private methods repository and entry_name to replace the
hardcoded HOMEBREW_REPOSITORY and formula path, and brew versions
work for both builtin and tapped formulae.

We should handle this case in some predictable way, but until we do,
let's raise a more appropriate exception. It would also be good to get
rid of the duplication here.
