Enhance the feedtype parameter to support ~2^32 feeds

[semmerson]

If the highest order bit is set, then treat the feed specification as a number and not a bitmask.

pqact(1) entries would have to be enhanced to support (e.g., "1000000 - 1000050").

All utilities that use a feedtype command-line argument would have to be modified.

CPU-s are fast enough nowadays to do this.

Old LDM-s might get confused?

The protocol would likely have to be incremented (LDM8?)
