[c-nsp] Maximum number of STP instances (Rapid PVST+) in 6500

[Clinton Work]

You will hit the per module limit of 1200 / 1800 using 802.1q trunks long 
before you hit the system wide limit.  Sup720s running IOS 12.2SX support 
the "sh vlan virtual-port" command to view the per-module virtual port counts.

My understanding is that the STP limits in the 12.2SX release notes were 
done using Sup2s and older WS-X61xx modules.  The Sup720 with new WS-X65xx, 
WS-X67xx, and WS-X68xx should be able to do more, but Cisco hasn't published 
any numbers.
