The new ISA v3.0 slbia variants have not been implemented for TCG,
which can lead to crashing when a POWER9 machine boots Linux using

did not mark the functions as such. As a result, clang (but not gcc)
fails to build with older glib unless -Wno-unused-function is enabled.

We have APIs which returns signed int64_t, to be able to return error.
Therefore we can't handle bitmaps with absolute size larger than
(INT64_MAX+1). Still, keep maximum to be INT64_MAX which is a bit
safer.
Note, that bitmaps are used to represent disk images

We have bdrv_dirty_bitmap_next_zero, let's add corresponding
bdrv_dirty_bitmap_next_dirty, which is more comfortable to use than
bitmap iterators in some cases.

The function is definitely internal (it's not used by third party and
it has complicated interface). Move it to .c file.

vfio_pfn.ref_count is always updated by holding iommu->lock, using atomic

I've tested smoe more cmbinations and found that I van have v4.2 work on focal.
Eventually I have realized that when I install start the qemu from Ubuntu not
only that but also the formerly working build of v4.2.0 from git start to fail
(without rebuilding).

Hi Laurent, I'm on a MacOS Mojave running Qemu installed by homebrew

The option to install was: `brew install --HEAD qemu -s --verbose`.
Maybe it's a Mac related problem?
