Nasty 0xe0 logic is gone. We map through QKeyCode now, giving us a
nice, readable mapping table.
Quick smoke test in OpenFirmware looks ok. Careful check from arch
maintainers would be very nice, especially on the capslock and numlock
logic. I'm not fully sure whenever I got it translated correctly and
also what it is supposed to do in the first place ...

s390x introduced helper functions for getting/setting one_regs with
commit 860643bc. However, nothing about these is s390-specific.
Alexey Kardashevskiy had already posted a general version, so let's
merge the two patches and massage the code a bit.

Some ONE_REGS on s390 are not protected by a capability. Older kernels
might not provide those and return an error. Fortunately these registers
are only critical for the migration path. There is no need to error out
on reset and normal runtime. Furthermore, these kernels don't provide
a proper dirty bitmap anyway, so let's use tracing for those errors.
Also provide generic one reg helper to simplify the code.

The throttling delay calculation was using an inaccurate sector count to
calculate the time to sleep. This broke rate-limiting for the block
mirror job.
Move the delay calculation into mirror_iteration() where we know how
many sectors were transferred. This lets us calculate an accurate delay
time.

n_start can be actually calculated from offset. The number of
sectors to be allocated(n_end - n_start) can be passed in in
num. By removing n_start and n_end, we can save two parameters.
The side effect is there is a bug in qcow2.c:preallocate() that
passes incorrect n_start to qcow2_alloc_cluster_offset() is
fixed. The bug can be triggerred by a larger cluster size than
the default value(65536), for example:
