Some people might want to run the gitlab CI pipelines in an environment
where multiple CPUs are available to the runners, so let's rather get
the number for "-j" from the "nproc" program (increased by 1 to compensate
for jobs that wait for I/O) instead of hard-coding it.

Currently all pipelines of the gitlab CI are failing, except for the
"build-user" pipeline. There is an issue with the default container
image (likely Debian stable) where they imported something bad in one
of the system headers:
/usr/include/linux/swab.h: In function '__swab':
/builds/huth/qemu/include/qemu/bitops.h:20:34: error: "sizeof" is not
defined, evaluates to 0 [-Werror=undef]
#define BITS_PER_LONG (sizeof (unsigned long) * BITS_PER_BYTE)
We could maybe work-around this issue or wait for the default containers
to get fixed, but considering that we use Ubuntu (and thus Debian-style)
CI in Travis already to a very large extent, we should consider to use
some RPM-based distros in our gitlab CI instead. Thus let's change the
failing pipelines to use Fedora and CentOS (and also one Ubuntu 19.10,
since 20.04 is broken, too) now.

* Assorted minor fixes and cleanups
It includes one patch to avoid a clash with SELinux when using NVLink

We shouldn't be messing around with the CPU list in linux-user save
for the very special case of do_fork(). When threads end we need to
properly follow QOM object lifetime handling and allow the eventual
cpu_common_unrealizefn to both remove the CPU and ensure any clean-up
actions are taken place, for example calling plugin exit hooks.
There is still a race condition to avoid so use the linux-user
specific clone_lock instead of the cpu_list_lock to avoid it.

Basing the cpu_index on the number of currently allocated vCPUs fails
when vCPUs aren't removed in a LIFO manner. This is especially true
when we are allocating a cpu_index for each guest thread in
linux-user where there is no ordering constraint on their allocation
and de-allocation.

Commit e47970f51d "s390x/cpumodel: Fix query-cpu-model-FOO error API
violations" neglected to change visit_check_struct()'s Error **
argument along with the others. If visit_check_struct() failed, we'd
take the success path. Fortunately, it can't fail here:
qobject_input_check_struct() checks we consumed the whole dictionary,
and to get here, we did. Fix it anyway.

usbback_portid_add() leaks the error when qdev_device_add() fails.
Fix that. While there, use the error to improve the error message.
The qemu_opts_from_qdict() similarly leaks on failure. But any
failure there is a programming error. Pass &error_abort.

If SELinux is setup without 'execmem' permission for qemu, all mmap
with (PROT_WRITE | PROT_EXEC) will fail and print a warning in
SELinux log.
If "nvlink2-mr" memory allocation fails (fist diff), it will cause
guest NUMA nodes to not be correctly configured (V100 memory will
not be visible for guest, nor its NUMA nodes).
Not having 'execmem' permission is intesting for virtual machines to
avoid buffer-overflow based attacks, and it's adopted in distros
like RHEL.
So, removing the PROT_EXEC flag seems the right thing to do.
Browsing some other code that mmaps memory for usage with
memory_region_init_ram_device_ptr, I could notice it's usual to
not have PROT_EXEC (only PROT_READ | PROT_WRITE), so it should be
no problem around this.
