merge: pass commitinfo to applyupdates() and get it stored in mergestate
This patch passes the commitinfo calulcated in manifestmerge() to applyupdates()
so that it can be read there and stored in mergestate. On commit, we can read
mergestate for such information and act accordingly.
This patch also makes ACTION_GET_OTHER_AND_STORE not required anymore. Next
patch will remove the messy code surrounding it.
