We stopped populating the element with real data some time ago, it's
time to drop it entirely.

Multiarch adds a Depends: foo:any syntax, permitted only if the
target of the dependency is "Multi-Arch: allowed". This has
been supported by dpkg and apt for some time and is now safe to
use in unstable.

"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.

If there are multiple versions of an arch:all package in unstable (due
to outdated or no longer built arch:any packages) then only one of them
should be recorded in the list of binary packages built from the source
package. Otherwise we may try and remove the binary package from various
lists multiple times, leading to crashes.

Given a source which provides two packages and has different versions
in testing and unstable, binNMUs in unstable corresponding to the
older source version should not be considered as migration candidates.
For example:
testing
-------
source 1
bin 1 arch1
bin 1 arch2
unstable
--------
source 2
bin 2 arch1
bin 1+b1 arch2
The binary migration on arch2 should not be considered a candidate.

Although this should never happen, rather than crashing if one of the
versions is none, simply indicate that they are unequal.

Although this isn't an issue during normal runs, the excuses might be
built multiple times during a hint-tester run and should not accumulate
during the run.
