After 4.16 release, Xen build system has been changed significantly.
When building latest status of Xen it was observed that commit
317c98cb91 broke the hypervisor build on arm32 due to the change in
handling Rules.mk that xen.inc modifies to override CC and CPP.
In order to fix the issue this patch moves overriding CC and CPP from
Rules.mk to make command line by adding them to EXTRA_OEMAKE:arm.
Take the opportunity to bump SRCREV of xen_git.bb and xen-tools_git.bb
to the current status of master.

Xen build may fail for arm machines that have enabled extra flags,
that can be enabled only for specific architecture version, e.g. armv8-2a.

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.

Ensure that the Xen build system variables EXTRA_CFLAGS_XEN_CORE and
EXTRA_CFLAGS_XEN_TOOLS are passed into the compile steps.
Update the hypervisor compilation to avoid passing in most compile flags
from the build environment via EXTRA_CFLAGS_XEN_CORE -- prefer the
compiler defaults and the flags set by the Xen build system, so only the
debug prefix flags are provided.
Observeration derived from the prior commit e99974aa, so:

If a recipe DEPENDS on xen we should include its binaries in the sysroot.
The do_install task also ships files to /boot and /usr/lib64. Hence, extend
SYSROOT_DIRS to include these paths.

When having rm_work and bitbake needs to re-run do_deploy, we need to ensure
that the ${B} is re-generated, otherwise the deploy-xen will be empty.

This patch introduces the following changes:
1. When building in OE environment the linker path needs to be passed when
buildind the Kconfig tool in order to get the menuconfig task properly
working.
2. By inheriting cml1.bbclass we can drop some environment variables
settings in xen-hypervisor.inc for the menuconfig task, and also be
able to search for config fragmens and use the diffconfig task. Also,
there is no need to have a custom do_menuconfig task anymore.

The deploy for the uncompressed image was checking if a .gz file exists,
it should instead check for a straight xen file.

Amend addtask for deploy in both recipes: add deploy before do_build to
ensure that it completes before the build step stamp is written.
Suggested-by: Bertrand Marquis <bertrand.marquis@arm.com>
Add comments explaining the scheduling of the deploy task to
both the hypervisor and tools recipes.
In the hypervisor build, change deploy to obtain files from ${B} rather
than ${D}, since it allows a bbappend to modify boot binary file
destinations in do_install without breaking do_deploy.
To ensure that a deployed hypervisor has matching tools in any image
being built, add a dependency to make sure that the tools have built and
been staged first:
do_deploy[depends] += "xen-tools:do_populate_sysroot"
Also add a dependency to ensure that anything that the tools recipe
deploys, such as a XSM policy file, has been deployed first:
do_deploy[depends] += "xen-tools:do_deploy"
Schedule deploy tasks after populate_sysroot to ensure that deployed
binaries match those staged for inclusion in the image rootfs.

Adds patches for packaged scripts to enable deployment with python3
where they have been ported to python 3 upstream.
setuptools3 inherits distutils3 which modifies ${B}, so cd ${S} is
needed in the do_configure, do_compile and do_install steps.
Remove python 2 dependency from the Xen recipes by adding a new
separate recipe, xen-python2, for packaging the remaining optional
scripts which are yet to be ported to python 3. Package naming in
the separate recipe is chosen to support transition back into the
xen-tools recipe if the scripts are ported later.
Use RSUGGESTS to support inclusion of the xen-python2 scripts in
images that include python 2.
Drop the remus package python dependency since the script was removed
in 2014: commit 5b66f84e37a45038f9e5dae7a5768a5525d1e6ba
Add python3 RDEPENDS needed to run xenmon.

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.
