Description of the change
Fix bug 1043762 (Incremental backups may take up to 5x more space
after the fix for bug #1022562).
Fix for bug 1022562 unconditionally copied first 64K of every
tablespace for incremental backups. In case of many tablespaces, that
creates huge deltas even in the absence of any changes.
Fixed by not requiring to copy the first 64K, but rather by creating
any missing tablespaces from scratch. Introduce new function
xb_delta_
fil_create_
Non-functional change, no testsuite changes necessary.
