The first commit creates a newtype for the weak/trivial attribute of package flags and stanzas.
The second commit fixes a bug in dependency solver stanza preferences. Previously, stanza choices were set to "weak" even when the stanza preference did not apply. See #3453 (comment).
@kosmikus Does it make sense to call the newtype
WeakOrTrivial
? I'm still not completely sure I understand the meaning of the weak/trivial fields in the solver'sFChoice
andSChoice
nodes.
