review of NFSv4.1/4.2 client side patch D29475

[Rick Macklem]

Hi,

If anyone would like to review D29475, which adds required support
for BindConnectionToSession, please do so.
--> Needed to make callbacks to continue working after a TCP
       reconnect occurs, due to a networking partition.

Until this patch is in a client, it is recommended to not run the
nfscbd(8) daemon, since the callback path may break after a
TCP reconnect.
