Message:

NEM,STAM: Partition memory statistics for NEM. bugref:9044

• STAM: Redid the way we handle statistics requiring fetching data from ring-0 (or elsewhere) by introducing a refresh group concept. We'll refresh the statistics for a group if needed and only once per enumeration/query. There's a new registration API for these.
• NEM: Added memory balance statistics for the partition. Some failed fumbling thru VID.DLL/SYS, before realizing that hypercall is the only way to get at them.
• NEM: Added a hypervisor input/output page buffer for non-EMT threads so we can get statistics. Put the related data and code into separate structure to save duplication.
