s390/sclpconsole: prevent char layer callback during initialization

Starting a qemu with an sclp console and pressing a key very early
can result in
"qemu-system-s390x: hw/s390x/sclpconsole.c:60: receive_from_chr_layer:
Assertion `scon->iov' failed."

Lets make sure that the init process is finished, since the iov is...

s390: Fix handling of iscs.

There are two ways to express an interruption subclass:
- As a bitmask, as used in cr6.
- As a number, as used in the I/O interruption word.

Unfortunately, we have treated to I/O interruption word as if it
contained the bitmask as well, which went unnoticed so far as...

target-s390x: Clean up cpu_inject_*() signatures

Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d947798cba92d836d06f6e017ba2b19d (s390:
I/O interrupt and machine check injection.) added functions

target-s390x: Pass S390CPU to s390_{add, del}_running_cpu()

This prepares for moving the halted field to CPUState.
Most call sites can already supply S390CPU, for some env becomes unused.

s390: Add s390-ccw-virtio machine.

virtio-ccw transport to present virtio devices as channel

s390: css error codes.

Changed error codes in the channel subsystem / virtio-ccw code
(-EOPNOTSUPP -> -ENOSYS, -ERESTART -> -EINPROGRESS).

This should hopefully fix building on mingw32.

s390: Drop set_bit usage in virtio_ccw.

set_bit on indicators doesn't go well on 32 bit targets:

note: expected 'long unsigned int *' but argument is of type 'uint64_t *'

Switch to bit shifts instead.

s390-virtio: Check for NULL device in reset hypercall

s390_virtio_bus_find_mem() may return a NULL VirtIOS390Device.
If called with, e.g., args0 == 0, this leads to a segfault.
Fix this by adding error handling as done for other hypercalls.

Present since baf0b55a9e57b909b1f8b0f732c0b10242867418 (Implement...
