Add a new DDB command, "show rmans", which will show the address and brief
details of each rman header, but not the contents of all rman structures in the system. This is especially useful on platforms where some rmans have many thousands of entries in rmans, making scrolling through the output of "show all rman" impractical. Individual rmans can then be viewed including their contents with "show rman 0xaddr" as usual. Reviewed by: jhb
