Add use of RCU for qemu_logfile.

This now allows changing the logfile while logging is active,
and also solves the issue of a seg fault while changing the logfile.

Any read access to the qemu_logfile handle will use
the rcu_read_lock()/unlock() around the use of the handle.
To fetch the handle we will use atomic_rcu_read().
We also in many cases do a check for validity of the
logfile handle before using it to deal with the case where the
file is closed and set to NULL.

The cases where we write to the qemu_logfile will use atomic_rcu_set().
Writers will also use call_rcu() with a newly added qemu_logfile_free
function for freeing/closing when readers have finished.

Also, some of the iotests crash when using "dist: bionic" on arm64

tests/boot-sector: Fix the bad s390x assembler code

There are currently two bugs in s390x_code[]: First, the initial jump
uses the wrong offset, so it was jumping to 0x10014 instead of 0x10010.
Second, LHI only loads the lower 32-bit of the register.

Everything worked fine as long as the s390-ccw bios code was jumping
here with r3 containing zeroes in the uppermost 48 bit - which just
happened to be the case so far by accident. But we can not rely on this
fact, and indeed one of the recent suggested patches to jump2ipl.c cause
the newer GCCs to put different values into r3. In that case the code
from s390x_code[] crashes very ungracefully.

Thus let's make sure to jump to the right instruction, and use LGHI
instead of LHI to make sure that we always zero out the upper bits
of the register.

 nothing at 0xf0000 and bugs ensue.
"

The pc-0.x machines have been marked as deprecated since QEMU v4.0, so
