After an OTA is applied, a wipe in recovery may overwrite components of dynamic partitions living in userdata. If the OTA has not yet begun merging, we mark the current slot unbootable. If the OTA has begun merging, we wait for the merge to complete. This logic is encapsulated in libsnapshot. Bug: 139156011 Test: manual test Change-Id: Id6544a1b8583afcbba11559d46214ec2e68ffa40
