solver3: Order obsolete choices last
This has two aspects:
1. For a dependency A | B | C we order the obsolete packages last,
that is, if A is obsolete, this gets reordered to B | C | A,
such that we try to pick non-obsolete packages first to ease
upgrade calculation.
2. When comparing two dependencies, we order dependencies into three
groups: First we satisfy dependencies mentioning only non-installed
(NEW) packages, then we satisfy "normal" dependencies, and finally
we satisfy any dependencies mentioning obsolete packages.
This means for example if you have obsolete libfoo1 and a new
libfoo1t64, that we will see Depends: libfoo1t64 before any
Depends: libfoo1 (which may expand to libfoo1 | libfoo1t64),
so we effectively will have selected "replacement" packages
this way already before getting to older packages where we
would have to choose between the obsolete package and its
replacement.
