The operations are to be used by an control domain to set parameters,
list pools, clients, and to be used during migration.
There is no need to have them in the tmem hypercall path.
This patch moves code without adding fixes - and in fact in
some cases makes the parameters soo long that they
We are doing another call to set_xen_guest_handle right

Manipulating the obj- structures requires us to hold the
pool-rwlock lock. Lets make that obvious in this function to
catch any errant users (none found, but we may in future).

Hey!
At the Xenhackathon we spoke that the tmem code needs a bit of cleanups
and simplification. One of the things that Andrew mentioned was that the
TMEM_CONTROL should really be part of the sysctl hypercall. As I ventured
this path I realized there were some other issues that need to be taken

When we are using shared pools we have an global array
(on which we put the pool), and an array of pools per domain.
We also have an shared list of clients (guests) _except_
for the very first domain that created the shared pool.
To deal with multiple guests using an shared pool we have an
