Enable chunk rename during log recovery

Whenever Informix performs a backup of the rootdbs, it automatically backs up Informix critical files (oncfg, onconfig & sqlhosts). When the Informix critical files are restored via "onbar -r -cf only -t <A TIMESTAMP>", it restores the latest files, ignoring the "-t" command line argument.

To restore Informix instance with chunk rename of say two day ago the process will be:

1. restore critical files backed up during the "onbar -b -L 0"

2. Parse oncfg

3. Create renamed disk subsystem to accomodate renamed instance

4. Generate informix restore file

5. Run restore

In cases a chunk (recall that the critical files are more recent), the restore as chunk did not exist in the Level 0. A typical error message is:

Unable to write storage space restore data to the database server: The old chunk path (<CHUNK PATH>, <CHUNK OFFSET>) in the input file does not exist in the backup..

This RFE is to allow onbar to continue if the the rename file contains more chunks that are not in the level 0 and also use the rename file during the logical logs apply.
