Move Formula.expand_dependencies into the Dependency class, and extend
it to allow arbitrary filters to be applied when enumerating deps.
When supplied with a block, expand_dependencies will yield a [dependent,
dependency] pair for each dependency, allowing callers to filter out
dependencies that may not be applicable or useful in a given situation.
Deps can be skipped by simple calling Dependency.prune in the block,
e.g.:
Dependency.expand_dependencies do |f, dep|
Dependency.prune if dep.to_formula.installed?
end
The return value of the method is the filtered list.
If no block is supplied, a default filter that omits optional or
recommended deps based on what the dependent formula has requested is
applied.
Formula#recursive_dependencies is now implemented on top of this,
allowing FormulaInstaller to exact detailed control over what deps are
installed. `brew missing` and `brew upgrade` can learn to use this to
apply the installed options set when expanding dependencies.
Move Formula.expand_deps and Formula#recursive_deps into compat, because
these methods do not respect the new optional and recommended tags and
thus should no longer be used.
