  s390x: Create QOM device for s390 storage keys

A new QOM style device is provided to back guest storage keys. A special
version for KVM is created, which handles the storage key access via
KVM_S390_GET_SKEYS and KVM_S390_SET_SKEYS ioctl.

  s390x: Enable new s390-storage-keys device

s390 guest initialization is modified to make use of new s390-storage-keys
device. Old code that globally allocated storage key array is removed.
The new device enables storage key access for kvm guests.

Cache storage key QOM objects in frequently used helper functions to avoid a
performance hit every time we use one of these functions.

  s390x: Dump storage keys qmp command

Provide a dump-skeys qmp command to allow the end user to dump storage
keys. This is useful for debugging problems with guest storage key support
within Qemu and for guest operating system developers.

  s390x: Migrate guest storage keys (initial memory only)

Routines to save/load guest storage keys are provided. register_savevm is
called to register them as migration handlers.

We prepare the protocol to support more complex parameters. So we will
later be able to support standby memory (having empty holes), compression
and "state live migration" like done for ram.
