183f6b8d7e sclp: sort into categories
Sort the sclp consoles into the input category, just as virtio-serial.
Various other sclp devices don't have an obvious category, sort them
into misc.

bb3e9e1fd7 s390x/sclpconsole: Avoid hanging SCLP ASCII console
Force recalculation of file descriptor sets for main loop's poll(),
in order to be able to readd a possibly removed input file descriptor
after can_read() returned 0 (zero).

35d08458a9 savevm: Remove all the unneeded version_minimum_id_old (rest)
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

b074e62205 s390x/sclpconsole: Fix and simplify interrupt injection

Turns out that we actually dont need the indirection, so trigger the
sclp interrupt directly.

c3d9f24a39 s390/eventfacility: allow childs to handle more than 1 event type
Currently all handlers (quiesce, console) only handle one event type.
Some drivers will handle multiple (compatible) event types. Rework the
code accordingly.

3af6de321f s390/sclp: add reset() functions
Add reset() functions for event-facility, sclpconsole, and sclpquiesce.
The reset() functions perform variable initialization
at IPL and e.g. when monitor system_reset is called.

ea9ad3e945 s390/sclpconsole: modify definition of input buffer
