merge: remove no longer required ACTION_GET_OTHER_AND_STORE
In
1b8fd4af33189c84feadb47c74d659ec31cde3b9 I (ab)used merge actions to pass
info from manifestmerge() to applyupdates() and store info in mergestate.
In previous patches, we introduced a separate return value from manifestmerge()
and calculateupdates() and an argument to applyupdates() which achieved the same
thing.
Let's remove this no longer required messy code.
