Use hmac-sha256 and rather than hmac-md5 that is used for CIFS/SMB.

Signature field in SMB2 header is 16 bytes instead of 8 bytes.

Automatically enable signing by client when requested by the server
when signing ability is available to the client.

This is help us to extend the code for future protocols that can use
another fid mechanism (as SMB2 that has it divided into two parts:
persistent and violatile).

Also rename variables and refactor the code around the changes.

Pull tile gxio ABI fix from Chris Metcalf:

Pull a Xen fix from Konrad Rzeszutek Wilk:
 "It is a bug-fix when we run the initial PV guest on a AMD K8 machine
  and have CONFIG_AMD_NUMA enabled and detect the NUMA topology from the
  Northbridge.

  We end up in the situation where the initial domain gets too much
  information and gets confused and crashes - the fix is to restrict the
  domain to get the information - and we do it by just disabling NUMA on
  the PV guest (the hypervisor is still able to do its proper NUMA
  allocations of guests).

  It is OK to disable the PV guest from accessing NUMA data as right now
  we do not inject any NUMA node information to the PV guests.  When we
  do get to that point, then this patch will have to be reverted."

 * Disable PV NUMA support as we do not do anything with it (yet) and it

An ABI numbering change was made in the hypervisor for Tilera's 4.1
MDE release (just shipped).  It's incompatible with the previous 4.0
release ABI numbering, so we track the new numbering going forward.
We plan to avoid modifying ABI numbering for these interfaces again.

The hypervisor is in charge of allocating the proper "NUMA" memory
and dealing with the CPU scheduler to keep them bound to the proper
NUMA node. The PV guests (and PVHVM) have no inkling of where they
run and do not need to know that right now. In the future we will
need to inject NUMA configuration data (if a guest spans two or more
NUMA nodes) so that the kernel can make the right choices. But those
patches are not yet present.

In the meantime, disable the NUMA capability in the PV guest, which
also fixes a bootup issue. Andre says:

"we see Dom0 crashes due to the kernel detecting the NUMA topology not
by ACPI, but directly from the northbridge (CONFIG_AMD_NUMA).

This will detect the actual NUMA config of the physical machine, but
will crash about the mismatch with Dom0's virtual memory. Variation of
the theme: Dom0 sees what it's not supposed to see.

This happens with the said config option enabled and on a machine where
this scanning is still enabled (K8 and Fam10h, not Bulldozer class)

We have this dump then:

so we just disable NUMA scanning by setting numa_off=1.
