Enable support for multipage folios on the 9P filesystem.  This is all
handled through netfslib and is already enabled on AFS and CIFS also.

Since this is fairly unrelated to the other patches let's take this
through the 9p tree as well - I'll run some quick tests to verify writes
go from 4k to something larger and it doesn't blow up immediately and
push it out for 6.11

(huh, my memory is rotten, we were already aggregating writes at some
point without this. Oh, well, at least it doesn't seem to blow up)
