The problem is that replay will unlink any segments which were on disk
at the time the replay starts. However, some of those segments may
have been created by current node since the boot. If a segment is part
of reserve for example, it will be unlinked by replay, but we will
still use that segment to log mutations. Those mutations will not be
visible to replay after a crash though.
The fix is to record preexisting segents before any new segments will
have a chance to be created and use that as the replay list.
Introduced in abe7358767.
