This removes the limit for p9 fids and the huge fid array that came along with
it. Instead, it dynamically allocates fids and stores them in a rb-tree.
This is useful when the guest needs a lot of fids, such as when stress
testing guests.

The current code will update the PPR on almost any APIC read; however
that's only required if we read the PPR.
kvm_update_ppr() shows up in some profiles, albeit with a low usage (~1%).
This should reduce it further (it will still be called during interrupt
processing).
