A new keyword `join` is introduced to generate the parent image. It
takes precedence over a `requires` or a `image` already defined in a
spec.
It will generate all the artifacts from the packages listed and join
them in a single image which will be used as parent for the package
build process.
This is a change which invalidates priorly generated hashes.
Fixes#173
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.
Fixes races conditions and make the DB Switchable. Also prepare inside
the CompilationSpec the tree of the deps to be built, and parallelize
only the building jobs.
Closes#7

Add CompilationSpecs type to handle slices of CompilationSpec, to
perform operation such as Unique() and Remove().
Add also dependencies and the spec associated to the Artifact, to track
how the artifact was generated.
Add revdeps compilation wrapper, and unit tests
Whenever we update the tree with new informations, all the sibilings
needs to be updated as well
Also switch to inmemory db for recipe - even if this should be a switch
