Revert "full/incremental backup method".

Browse Source 
This method was introduced in cad595f but on further reflection it does not seem worth the added complexity just to make restore consistency faster without improving the speed of the overall backup. The most common recovery case is PITR and this method produces diminishing returns as the recovery time gets further from the backup end time.

A better solution (not implemented here) is to copy unmodified files from prior backups. This is much faster than recopying and compressing files from the cluster (especially on object stores with a copy command) and can even be done after the backup window to further reduce WAL replay required for consistency. It also reduces load on the host where the backup is made.
