When there isn't a version-script for a shared library (like for
unstable libs), we create one based on the current Xen version. But
that version-script became out-of-date as soon as Xen's version
changes and make as no way to regenerate the version-script on
rebuild.
For unstable libs, we only needs the symver to be different from a
previous release of Xen. There's an option "--default-symver" which
allow to use the soname as symver and as the soname have the Xen
release version, it will be different for every release. With
--default-symver we don't need to generate a version-script.
But we also need to know if there's already an existing version script
, for that we introduce $(version-script) to be used to point to the
path of the existing script. (Guessing if a version script exist for a
stable library with for example $(wildcard) won't work as a file will
exist when building the library without this patch.)
We don't need the version-script unless we are making the shared
library so it is removed from the "all" target.

html output when the script is called with --cppcheck-html.
With this patch cppcheck will benefit of platform configuration files
that will help it to understand the target of the compilation and
improve the analysis. These are XML files placed in
xen/tools/cppcheck-plat/, describing to cppcheck the length of basic

To do so:
- Update xen-analysis.py with the code to integrate cppcheck.
- add platform configuration files for cppcheck..
- add cppcheck-cc.sh script that is a wrapper for cppcheck and it's
used as Xen compiler, it will intercept all flags given from the

We can't have a source file with the same name that exist in both the
common code and in the arch specific code for efi/. This can lead to
confusion in make and it can pick up the wrong source file. This issue
lead to a failure to build a pv-shim for x86 out-of-tree, as this is
one example of an x86 build using the efi/stub.c.
The issue is that in out-of-tree, make might find x86/efi/stub.c via
VPATH, but as the target needs to be rebuilt due to FORCE, make
actually avoid changing the source tree and rebuilt the target with
VPATH ignored, so $@ lead to the build tree where "stub.c" doesn't
exist yet so a link is made to "common/stub.c".
Rework the new common/stub.c file to have a different name than the
already existing one, by renaming the existing one. We can hide the
compat aliases that x86 uses behind CONFIG_COMPAT so a Arm build will
not have them.
Also revert the change to the rule that creates symbolic links it's
better to just recreate the link in cases where an existing file exist
or the link goes to the wrong file.
Avoid using $(EFIOBJ-y) as an alias for $(clean-files), add
"stub.c" directly to $(clean-files).
Also update .gitignore as this was also missing from the original

cppcheck can be used to check Xen code quality.
To create a report do "make cppcheck" on a built tree adding any options
you added during the process you used to build xen (like CROSS_COMPILE
or XEN_TARGET_ARCH). This will generate an xml report xen-cppcheck.xml.
To create a html report do "make cppcheck-html" in the same way and a
full report to be seen in a browser will be generated in
cppcheck-htmlreport/index.html.
For better results it is recommended to build your own cppcheck from the
latest sources that you can find at [1].
Development and result analysis has been done with cppcheck 2.7.
The Makefile rule is searching for all C files which have been compiled
(ie which have a generated .o file) and is running cppcheck on all of
them using the current configuration of xen so only the code actually
compiled is checked.
A new tool is introduced to merge all cppcheck reports into one global
report including all findings and removing duplicates.
Some extra variables can be used to customize the report:
- CPPCHECK can be used to give the full path to the cppcheck binary to
use (default is to use the one from the standard path).
- CPPCHECK_HTMLREPORT can be used to give the full path to
cppcheck-htmlreport (default is to use the one from the standard path).
This has been tested on several arm configurations (x86 should work but
has not been tested).

This patch adds support for bundling the xen.efi hypervisor, the xen.cfg
configuration file, the Linux kernel and initrd, as well as the XSM,
and architectural specific files into a single "unified" EFI executable.
This allows an administrator to update the components independently
without requiring rebuilding xen, as well as to replace the components
in an existing image.
The resulting EFI executable can be invoked directly from the UEFI Boot
Manager, removing the need to use a separate loader like grub as well
as removing dependencies on local filesystem access. And since it is
a single file, it can be signed and validated by UEFI Secure Boot without
requring the shim protocol.
It is inspired by systemd-boot's unified kernel technique and borrows the
function to locate PE sections from systemd's LGPL'ed code. During EFI
boot, Xen looks at its own loaded image to locate the PE sections for
the Xen configuration (`.config`), dom0 kernel (`.kernel`), dom0 initrd
(`.ramdisk`), and XSM config (`.xsm`), which are included after building
xen.efi using objcopy to add named sections for each input file.
For x86, the CPU ucode can be included in a section named `.ucode`,
which is loaded in the efi_arch_cfg_file_late() stage of the boot process.
On ARM systems the Device Tree can be included in a section named
`.dtb`, which is loaded during the efi_arch_cfg_file_early() stage of
the boot process.
Note that the system will fall back to loading files from disk if
the named sections do not exist. This allows distributions to continue
with the status quo if they want a signed kernel + config, while still
allowing a user provided initrd (which is how the shim protocol currently
works as well).
This patch also adds constness to the section parameter of
efi_arch_cfg_file_early() and efi_arch_cfg_file_late(),
changes pe_find_section() to use a const CHAR16 section name,
and adds pe_name_compare() to match section names.

Carve out all libxenlight related sources and move them to
tools/libs/light in order to use the generic library build environment.
The closely related sources for libxl-save-helper and the libxl test
environment are being moved, too.
