s390/ioinst: Moved the CC setting to the IO instruction handlers

The IO instruction handlers now take care of setting the CC value on
their own, so that the confusing return code magic in kvm_handle_css_inst()
is not needed anymore.

qcow2: Correct snapshots size for overlap check

Using s->snapshots_size instead of snapshots_size for the metadata
overlap check in qcow2_write_snapshots leads to the detection of an
overlap with the main qcow2 image header when deleting the last
snapshot, since s->snapshots_size has not yet been updated and is
therefore non-zero. However, the offset returned by qcow2_alloc_clusters
will be zero since snapshots_size is zero. Therefore, an overlap is
detected albeit no such will occur.

This patch fixes this by replacing s->snapshots_size by snapshots_size
when calling qcow2_pre_write_overlap_check.

s390/kexec: Implement diag308 subcode 0

This patch implements subcode 0 of diag 308. This is necessary for kexec
(without kdump). The main difference to subcode 1 is that all CPUs get
a full reset, instead of the architectured CPU reset (which leaves all
registers untouched).

s390/sclpconsole: modify definition of input buffer

To use VMState for migration, we need to adapt some sclp code:
   - allocate console buffer as part of the console
   - change semantic of sclpconsole offset fields

s390/eventfacility: Fix receive/send masks

Currently we announce interchanged receive/send masks. This did not
trigger a bug, since the sclp console has the same masks for
send/receive and the Linux guest does not check the sclp mask for simple
events like quiesce. With other event users like the sclp line mode
console, we will have different send/receive bits. Fix it.
