[pnfs] 4.1-sessions and master merge complete

[Marc Eshel]

Hi all,
I did some testing for the master branch that includes both the latest 
session and pNFS updates and most of the tests (mainly reads and writes) 
seems to work fine. There is some problem that seems to appear randomly at 
different points of the operations and is not easily re-creatable. I am 
attaching some sections of the errors messages on the client side maybe 
someone have some ideas where this is coming from.
Marc.
