Adds a --components command line argument (and corresponding config file
option). If specified, package info is expected to be in the usual Debian
mirror layout, ie:
testing/source/Sources
testing/binary-${ARCH}/Packages

A package can have old cruft no longer in testing, which can't
migrate because it depends on old libraries or packages that
aren't in testing anymore, preventing migration.
There's no point in trying to migrate old cruft that has already
been removed in testing anyway, so don't do that.

The "include_hijacked" parameter of "_compute_groups" was always
false, so there was little point in having it.

The same_source is supposed to compare two versions and (if needed)
"massage" a binNMU version into a source version. This extra feature
of same_source happens to be unused (and not generally applicable):
1) We always compare two source versions, so there is never a
binNMU version in the first place.
2) binary versions are *not* always equal to their source version
(even with the binNMU suffix stripped). This happens when
packages use "dpkg-gencontrol -v<version>".
Note this causes results from some live-data tests to change, because
there has been a sourceful upload with a binNMU version. It was
intended as a binNMU, but was uploaded with the source as well. As
Britney no longer works around this issue, it makes her remove the
affected packages in the end (as their source version does not match
the version in testing).

This bug involves a corner case that involves:
* source orig providing liborig1 and orig-doc in testing
* source orig providing liborig2 and orig-doc in unstable
* source hijack providing liborig2 and orig-doc in both testing and unstable,
where the versions of hijack's binaries has a higher version than those of
"orig".
The arch:all packages are needed to trigger this, because Britney
flags an arch:any package as "out of date" and stops the migration
there. However, she is more lenient with arch:all packages.
What happens is that Britney realises that src:orig need to be updated
in testing (to remove liborig1). This leaves src:orig with no
binaries left in testing (as the orig-doc from hijack is used) and it
is therefore removed as an obsolete source. The obsolete removal then
exploded because Britney was also trying to remove the liborig1
package, which is no longer there.

With this patch, Britney will correctly parse (and deparse) a
versioned Provides. Furthermore, she will allow it to satisfy any
unversioned dependency on the provided package.
This is the easy half of #786803.

It can be used to A) to make the mismatch check more efficient and B)
share identical binaries between suites.

Previously whether such packages received excuses, and the specific
content of such excuses, was dependent on the order in which their
binary packages were considered.

Technically, we simply sort by the "hint-size", but it for most parts
have the effect of putting single item earlier. Note this is /not/ a
perfect solution, but it is a simple heuristic exploiting the common
case.

This made iter_packages_hint a thin wrapper around try_migration, so
it was inlined into its only caller "do_all".
