Rewrite, rename and extend find_upgraded_binaries

Browse Source 
Rename find_upgraded_binaries into _compute_groups.  The new method
will also compute what binaries will be updated in or added to testing
after migration.

"""Compute the groups of binaries being migrated by item
This method will compute the binaries that will be replaced in
testing and which of them are smooth updatable.
This method will compute the binaries that will be added,
replaced in testing and which of them are smooth updatable.
Parameters:
* "source_name" is the name of the source package, whose
binaries are migrating.
* "source_data" is the fields of that source package from
testing.
* "architecture" is the architecture determines architecture of
the migrating binaries (can be "source" for a
"source"-migration, meaning all binaries regardless of
architecture).
* "suite" is the suite from which the binaries are migrating.
[Same as item.suite, where available]
* "migration_architecture" is the architecture determines
architecture of the migrating binaries (can be "source" for
a "source"-migration, meaning all binaries regardless of
architecture). [Same as item.architecture, where available]
* "is_removal" is a boolean determining if this is a removal
or not [Same as item.is_removal, where available]
* "include_hijacked" determines whether hijacked binaries should
be included in results or not. (defaults: False)
Returns a tuple (adds, rms, smoothbins). "adds" is a set of
binaries that will updated in or appear after the migration.
"rms" is a set of binaries that are not smooth-updatable (or
binaries that could be, but there is no reason to let them be
smooth updated). "smoothbins" is set of binaries that are to
be smooth-updated.
Each "binary" in "adds", "rms" and "smoothbins" will be a
tuple of ("package-name", "version", "architecture") and are
thus tuples suitable for passing on to the
InstallabilityTester.
Returns a tuple (bins, smoothbins). "bins" is a set of binaries
that are not smooth-updatable (or binaries that could be, but
there is no reason to let them be smooth updated).
"smoothbins" is set of binaries that are to be smooth-updated
Pre-Conditions: The source package must be in testing and this
should only be used when considering to do an upgrade
migration from the input suite. (e.g. do not use this for
removals).
