libnfs-raw.h: rename export -> exportname to avoid clash with C++ keyword
From http://en.cppreference.com/w/cpp/keyword/export :
Until C++11:
"Used to mark a template definition exported, which allows the same
template to be declared, but not defined, in other translation units."
Since C++11:
"The keyword is unused and reserved."

Add a mechanism to control what the next XID value on a session will be.
This makes it possible for multiple processes/contexts to use the same
target and (with some synchronization) avoid XID collissions across processes/contexts.

Mix in the pid in the top 16 bits for the initial xid.
This helps for users which rapidly fork a lot of processes that then
immediately create a new context (I am looking at you dbench)
to awoid having lots of processes starting and using overlapping xid values.

Don't clamp write3 max to 32k
We use our own XDR and RPC layer nowadays and do not have
any external dependencies to XDR or RPC.
As such we no longer need to clamp the write size to max 32kb
since we never link to the system rpc/xdr libraries.
(and thus dont have to clamp in case the system library is broken for
pdu's > 32k)
