implement provides

Packages should be able to export tags which can be used in dependencies.

E.g. vlc could export tag plugin-api=2. And clients could depend on vlc(plugin-api)>=2 instead of exact version number.

This is basically same as “provides”. Provides support is just more generic, especially if we allow versioned provides, e.g. “provides=vlc-plugin-api=2”. If we don’t want to pollute the regular package namespace we can allow some special character in provides, e.g. “provides=vlc:plugin-api=2”.

solver: have most inherited things per-package and clean ups

Required for provides support as package might be pulled in via
non-primary package name. This allows relatively easily to pass
through inherited flags via the provided names. ref #574.
