[William Grant]

[r=lifeless][bug=750640] Fix Source field generation rules in NMAF Packages files.

Stanzas in apt Packages files only need to include the Source field if the details differ from the binary's. If the name differs, it should be "Source: sourcename". If the version differs, it should be "Source: sourcename (sourceversion)". NMAF always acts as if the name differs, never omitting the field nor including the version.

This branch fixes that behaviour, and adds tests.

[Robert Collins (lifeless)]

+def get_field(stanza_fields, name):
30 + for key, value in stanza_fields.fields:
31 + if key == name:
32 + return value

isn't that just
dict(stanza_fields.fields).get(name)
?
