Add recovery test for missing redo segment with backup_label This commit adds a test case for early startup where a backup_label file uses a checkpoint LSN and a redo LSN located in two different segments, where the segment of the redo LSN is missing. This code has never been covered, and is complex enough that a test case is going to be useful in the long-term.
Nitin has proposed a more complex approach than what is added by this commit, by forcing a reuse of the injection points to produce a split between redo and checkpoint. This commit relies on the checkpoint and redo LSNs generated by the first steps of the test, combined with a generated backup_label, making the whole cheaper.
