Consider the transitive closure of availability #5

The current policy in the opam repository is to only tag the root packages as unavailable for a given compiler version or OS. This helps having more precise error message in opam, for instance:

$ opam install core_bench.109.55.00
The following dependencies couldn't be met:
  - core_bench -> core = 109.55.00 -> custom_printf = 109.27.00
Your request can't be satisfied:
  - custom_printf.109.27.00 is not available because it requires OCaml < 4.02.0.

Which is much more useful feedback than core_bench.109.55.00 requires OCaml < 4.02. Forcing the package maintainer to fix that would be a mistake, in my opinion.

In the reports, you mark custom_printf.109.27.00 as "unavailable" but core_bench.109.55.00 as broken: I think this is the wrong feedback you want to give to package maintainer.
