Defrag should leave / add freespace to PDS with 0 Secondary extents

When DSS is defragmenting a volume, add an optional parameter FREE%(nn default 10, nn default 10) that applies to DSORG=PO,SPACE=(qty,(prm,0,dir)) that the resulting DSORG=PO have nn% free space and nn% free directory blocks).

When DSS is defragmenting a dataset(s), add an optional parameter FREE(qty,(prm,sec,dir)) that is like the SPACE JCL parameter except it is space in addition to what is in use, or FREE(PCT,(prm,sec,dir)) is a percentage above what is in use.

Due to the reblocking needs when adding directory blocks, for RECFM=U (or all DSORG=PO datasets), if more directory blocks are needed either add an exact multiple of a track's worth of directory blocks, and / or fill the partial track with directory blocks displacing the start of the member area.

    This item is a valid requirement but unlikely to be given high enough priority to be placed into the product plan. If this requirement is high value, please re-open it, or open a new requirement.
