"easy foo/1 bar/2" and "easy bar/2 foo/1" are simply different ways of
writing the same hint, so the corresponding Hint objects should compare
as equal.

So far we only check that hints which should have version information
do (and those which should not do not).

As HintItem is now redundant, also replace it with a new class -
UnversionnedMigrationItem - and migrate users of the classes to use
the new versions.

This function allows a textual representation of a package (e.g.
"foo/amd64") to be convered to a HintItem().

Where possible, avoid creating a list only to discard immediately
afterwards. Example:
"""
for x in sorted([x for x in ...]):
...
"""
Creates a list, passes it to sorted, which generates a new list and
sorts that copy. Since sorted accepts an iterable, we can avoid the
"inner" list and just pass it a generator expression instead.

By moving the package loop inside register_reverses, it will be
invoked a lot less (reducing the overhead of invoking functions).

Beside some "minor differences" they were computing the same "tree"
(read: "graph"), so merge them into one (get_reverse_tree) and
properly document return value and special cases.

Rewrite the arguments of find_upgraded_binaries to not use an instance
of MigrationItem. We want to call it at a time where we have not
created MigrationItems yet.

A removal hint will generate both source and per-arch excuses if the
version of the source package differs between testing and unstable. If
the source versions are the same then only the per-arch excuses will
be generated.

In rare cases with hints with overlapping virtual packages provided by
different sources, this can make a difference.
