OEcore/bitbake are moving to use the clearer ":" as an overrides
separator.
This is pass one of updating the meta-virt recipes to use that
syntax.
This has only been minimally build/runtime tested, more changes
will be required for missed overrides, or incorrect conversions
Note: A recent bitbake is required:

bitbake: data_smart/parse: Allow ':' characters in variable/function names
It is becomming increasingly clear we need to find a way to show what
is/is not an override in our syntax. We need to do this in a way which
is clear to users, readable and in a way we can transition to.
The most effective way I've found to this is to use the ":" charater
to directly replace "_" where an override is being specified. This
includes "append", "prepend" and "remove" which are effectively special
override directives.
This patch simply adds the character to the parser so bitbake accepts
the value but maps it back to "_" internally so there is no behaviour
change.
This change is simple enough it could potentially be backported to older
version of bitbake meaning layers using the new syntax/markup could
work with older releases. Even if other no other changes are accepted
at this time and we don't backport, it does set us on a path where at
some point in future we could
require a more explict syntax.
I've tested this patch by converting oe-core/meta-yocto to the new
syntax for overrides (9000+ changes) and then seeing that builds
continue to work with this patch.

The Xen hypervisor built for Arm 64-bit targets can be launched with
runqemu by providing a Device Tree binary and configuration for Qemu,
which enables interactive testing of Xen images.
Add qemuboot-xen-dtb.bbclass to add a new bitbake task for generating
the dtb file by using lopper on a device tree produced by Qemu.
Add qemuboot-xen-defaults.bbclass to supply working default parameters
for the qemuarm64 machine and general support for qemuboot for Xen,
and adjust the defaults as needed to boot successfully in testing.

Sometimes Xen is built with different mixes of kernel modules and
built-in values. If we put our expected/default modules in a
variable, they can be overriden by a different kernel provider
as required

runqemu is looking for the QB_DEFAULT_KERNEL to be set to "none"
to trigger special processing. The current set of QB_DEFAULT_KERNEL=""
won't trigger that behaviour .. so we change the default.
We also make the assignments weak, to allow easier overrides in
specific implementations.
We also need a patch to qemuboot.bbclass to make the defaults ??=,
and when that is done, our ?= here will work properly.

Booting this Xen image with QEMU works when launching from the
wic-generated pcbios disk image with the directdisk-xen.wks kickstart
file, so add the variable settings to make doing it simple -- eg:
runqemu xen-image-minimal nographic slirp
Tested with MACHINEs: qemux86-64 and genericx86-64
Memory allocated to qemu is increased slightly over the default to allow
for running Xen and the Linux dom0 and guest VMs.

This change changes the names of many packages produced: the
xen-tools recipe now builds packages previous built by the xen
recipe, so the package prefix changes from "xen-" to "xen-tools-".
A temporary bbappend is provided for qemu to ease the transition.
Multiple motivations for recipe separation:
- improves efficiency of incremental build and development
- supports building the hypervisor and tools with different toolchains
and for different architectures
Switch to using a git recipe on the Xen stable branch:
- enables easier tracking of critical XSA security updates applied
upstream by just advancing SRCREV along the branch
Revision has been set to the tip of the stable-4.12 branch, which
has the one XSA-312 patch applied on top of RELEASE-4.12.2.
The recipe refactor externalizes the block tap components, to enable optional
building of blktap in a separate recipe outside xen-tools, needed by OpenXT.
xenstored is made a virtual package to support switching between
alternative implementations (several exist).
Update xen-image-minimal to install the xen-tools package, which
replaces what was previously xen-base.
Determine the flask policy filename, which is Xen-version specific,
using the same method as the Xen build system.
qemu: update PACKAGECONFIG[xen] for xen package renaming: allows builds
to continue correctly in the meantime while openembedded core and poky
are updated.

The logic for restricting the xen-pciback kernel module to x86-only
images was incorrect, resulting in the IMAGE_INSTALL_x86 and _x86-64
variables causing the IMAGE_INSTALL variable contents to be
overridden and incomplete.
This correction removes the specialized IMAGE_INSTALL_x86 and _x84-64
variables. The replacement logic causes a value with
conditionally-populated contents to be added to the IMAGE_INSTALL
variable.

This commit fixes the xen-image-minimal build for non-x86 arch with PCI enabled.
The Linux kernel option CONFIG_XEN_PCIDEV_BACKEND currently depends on X86.
This means that the xen-pciback kernel module cannot be included in this image
for non-x86 architecture builds, so don't attempt to install it in that case.
