Enforce solver constraints
- Don't sign installed packages during finalizer execution
- Enforce solver constraints: build ALO and AMO rules taking into account
  that the current package might not be selected at all.
- Force uninstalls on upgrade
- Enable option to tell uninstall to ignore conflict with the analized system state,
  as we don't want any conflict with the installed to raise during the upgrade.
  In this way we both force uninstalls and we avoid to check with conflicts
  against the current system state which is pending to deletion.
  This is due to the fact that now the solver enforces the constraints
  and explictly denies two packages of the same version installed.
- Adapt test as now we generate more constraints, which makes the solver more
  noisy on the package that are explictly selected or not

15250bd991 Add support for Package provides
Add "provides" field in packages (which affect both runtime and buildtime deps).
It replaces all the occurences in the deptree before solving, actually
allowing to swap packages and provide virtuals. Along with a mechanism
for package rename #25.

d583fa8bf5 Force the solver to look at the best match first
Add support clauses to force the solver to look after the best match
first.

Closes #29

Do not allow multiple versions in the results
This happens because we select the best instead of selecting the best match in Package BuildFormula()

- Extend the selection test
- Select from databases when ordering
- Relax assertions search
- Split compile step in test
- Adapt tests

Note: This is temporarly until we treat this case in BuildFormula() inside Package
we need to build the constraints between all the requires when expanding
and then create a new constraint that selects the best match

Make solver consume databases instead of world lists
first step - it is slower in the implementation for now, but all cases
seems to be sorted out.
Drop Flagged() and IsSet() from solver. the solver wont care, and only
the assertion value does matter (exception for uninstall)

Add uninstall
Uninstall can be done in different ways - the most accurate would be to try find a minimum subset of packages that gives conflicts and try to reduce them gradually.
E.g. this could be done with other SAT algorithms. For now we keep things simple and we compute the uninstalls as an indirect of an installation from an empty profile.

Also take care of corner cases where world has no clauses, and fixes a typo in building the world formula
