Allow to specify the container engine to run with ENGINE variable.
By default, ENGINE=auto and will select either podman or docker.

Add a --engine option to select either docker, podman or auto.
Among other advantages, podman allows to run rootless & daemonless
containers, fortunately sharing compatible CLI with docker.
With current podman, we have to use a uidmap trick in order to be able
to rw-share the ccache directory with the container user.
With a user 1000, the default mapping is: 1000 (host) -> 0 (container).
So write access to /var/tmp/ccache ends will end with permission
denied error.
With "--uidmap 1000:0:1 --uidmap 0:1:1000", the mapping is:
1000 (host) -> 0 (container, 1st namespace) -> 1000 (container, 2nd namespace).
(the rest is mumbo jumbo to avoid holes in the range of UIDs)
A future podman version may have an option such as --userns-keep-uid.
Thanks to Debarshi Ray <rishi@redhat.com> for the help!

There's a race condition in which the tcp_chr_read() ioc handler can
close a connection that is being written to from another thread.
Running iotest 136 in a loop triggers this problem and crashes QEMU.

After g_source_attach() the GMainContext holds a reference to the
GSource, so the caller does not need to keep it.
qio_task_thread_worker() is not releasing its reference so the GSource

The old memory_region_{add|clear}_coalescing() has some defects
because they both changed mr->coalesced before updating the regions
using memory_region_update_coalesced_range_as(). Then when the
regions were updated in memory_region_update_coalesced_range_as() the
mr->coalesced will always be either one more or one less. So:
- For memory_region_add_coalescing: it'll always trying to remove the
newly added coalesced region while it shouldn't, and,
- For memory_region_clear_coalescing: when it calls the update there
will be no coalesced ranges on mr->coalesced because they were all
removed before hand so the update will probably do nothing for real.
Let's fix this. Now we've got flat_range_coalesced_io_notify() to
notify a single CoalescedMemoryRange instance change, so use it in the
existing memory_region_update_coalesced_range() logic by only notify
either an addition or deletion. Then we hammer both the
memory_region_{add|clear}_coalescing() to use it.

The has_coalesced_range could potentially be problematic in that it
only works for additions of coalesced mmio ranges but not deletions.
The reason is that has_coalesced_range information can be lost when
the FlatView updates the topology again when the updated region is not
covering the coalesced regions. When that happens, due to
flatrange_equal() is not checking against has_coalesced_range, the new
FlatRange will be seen as the same one as the old and the new
instance (whose has_coalesced_range will be zero) will replace the old
instance (whose has_coalesced_range _could_ be non-zero).
The counter was originally used to make sure every FlatRange will only
notify once for coalesced_io_{add|del} memory listeners, because each
FlatRange can be used by multiple address spaces, so logically
speaking it could be called multiple times. However we should not
limit that, because memory listeners should will only be registered
with specific address space rather than multiple address spaces.
So let's fix this up by simply removing the whole has_coalesced_range.

It is a workaround of current KVM's KVM_UNREGISTER_COALESCED_MMIO
interface. The kernel interface only allows to unregister an mmio
device with exactly the zone size when registered, or any smaller zone
that is included in the device mmio zone. It does not support the
userspace to specify a very large zone to remove all the small mmio
devices within the zone covered.
Logically speaking it would be nicer to fix this from KVM side, though
in all cases we still need to coop with old kernels so let's do this.

Defining CONFIG_TOOLS on the basis of $(TOOLS) has the disadvantage
of including it also if e.g. qemu-ga is requested. The correct
information is available in configure, define it there.

tools if the only "tool" being built is the guest agent.

The POWER8 and POWER9 User's Manuals specify the implementation
behavior for what the ISA leaves "undefined" behavior for the
xscvdpspn and xscvdpsp instructions. This patch corrects the QEMU
implementation to match the hardware implementation for that case.
ISA 3.0B has xscvdpspn leaving its result in word 0 of the target register,
with the other words of the target register left "undefined".
The User's Manuals specify:
VSX scalar convert from double-precision to single-precision (xscvdpsp,
xscvdpspn).
VSR[32:63] is set to VSR[0:31].
So, words 0 and 1 both contain the result.
Note: this is important because GCC as of version 8 or so, assumes and takes
advantage of this behavior to optimize the following sequence:
xscvdpspn vs0,vs1
mffprwz r8,f0
ISA 3.0B has xscvdpspn leaving its result in word 0 of the target register,
and mffprwz expecting its input to come from word 1 of the source register.
This sequence fails with QEMU, as a shift is required between those two
instructions. However, since the hardware splats the result to both words 0
and 1 of its output register, the shift is not necessary.
Expect a future revision of the ISA to specify this behavior.

ISA 3.0B added a set of Floating-Point Status and Control Register (FPSCR)
instructions: mffsce, mffscdrn, mffscdrni, mffscrn, mffscrni, mffsl.
This patch adds support for 'mffsl'.
'mffsl' is identical to 'mffs', except it only returns mode, status, and enable
bits from the FPSCR.
On CPUs without support for 'mffsl' (below ISA 3.0), the 'mffsl' instruction
will execute identically to 'mffs'.
Note: I renamed FPSCR_RN to FPSCR_RN0 so I could create an FPSCR_RN mask which
is both bits of the FPSCR rounding mode, as defined in the ISA.
I also fixed a typo in the definition of FPSCR_FR.

v4:
- nit: added some braces to resolve a checkpatch complaint.
v3:
- Changed tcg_gen_and_i64 to tcg_gen_andi_i64, eliminating the need for a
temporary, per review from Richard Henderson.
v2:
- I found that I copied too much of the 'mffs' implementation.
The 'Rc' condition code bits are not needed for 'mffsl'. Removed.
- I now free the (renamed) 'tmask' temporary.
- I now bail early for older ISA to the original 'mffs' implementation.

DPDES stores a status of a doorbell message and if it is lost in
migration, the destination CPU won't receive it. This does not hit us
much as IPIs complete too quick to catch a pending one and even if
we missed one, broadcasts happen often enough to wake that CPU.
This defines DPDES and registers with KVM for migration.

If an IRQ is allocated and not configured, such as a MSI requested by
a PCI driver, it can be saved in its default state and possibly later
on restored using the same state. If not initially MASKED, KVM will
try to find a matching priority/target tuple for the interrupt and
fail to restore the VM because 0/0 is not a valid target.
When allocating a IRQ number, the EAS should be set to a sane default :
VALID and MASKED.

Linux guest kernels have code which scans the string of characters
returned from the H_GET_TERM_CHAR hypercall and removes any \0
character which comes immediately after a \r character. This is to
work around a bug which was present in some ancient versions of
PowerVM. In order to avoid the corruption of the console byte stream
that this introduced, commit 6c3bc244d3cb ("spapr: Implement bug in
spapr-vty device to be compatible with PowerVM") added a workaround
which adds a \0 character after every \r character. Unfortunately,
this corrupts the console byte stream for those operating systems,
such as AIX, which don't remove the null bytes.
We can avoid triggering the Linux kernel workaround if we avoid
returning a buffer which contains a \0 after a \r. We can do that by
breaking out of the loop in vty_getchars() if we are about to insert a
\0 and the previous character in the buffer is a \r. That means we
return the characters up to the \r for the current H_GET_TERM_CHAR,
and the characters starting with the \0 for the next one.
With this workaround, we don't insert any spurious characters and we
avoid triggering the Linux kernel workaround, so the guest will
receive an uncorrupted stream whether or not they have the workaround.

When freeing MSIs, we need to:
- remove them from the machine's MSI bitmap
- remove them from the IC backend
- remove them from the PHB's MSI cache
This is currently open coded in two places in rtas_ibm_change_msi(),
and we're about to need this in spapr_phb_reset() as well. Instead of
duplicating this code again, make it a destroy function for the PHB's
MSI cache. Removing an MSI device from the cache will call the destroy
function internally.
