[PATCH] xl.conf defaults changes for Xen 4.4. (v1).

[Konrad Rzeszutek Wilk <konrad@kernel.org>]

Hey George and Ian,

During the Xen 4.3 release we briefly chatted about enabling and
providing an seatbelt parameter for some of the functionality
that libxl provides. In particular these were:
 - xl vcpu-set - it has an host check such that the vCPU cannot be
                 set higher than the pCPU. But a user can set such
                 values in the guest config and launch an over-subscribed
                 guest without any warnings. (Perhaps we should add
                 a warning for that as well? Or don't launch the guest?)
 - claim_mode - The functionality here is not just specific to tmem enabled
                 guests. Any generic guest can benefit from this and it
                 allows the user to get up-to-date memory information on how
                 much free memory there really is - and how much is being
                 consumed for the guest creation. By default it is disabled.
                 This turns it on by default.

Please see the patches and enjoy reviewing them. I've asbestos jumpsuit 
ready in case this discussion gets heated.
