Shawn Anastasio 0595f96854 automation: Change build script to use arch defconfig
Change automation build script to call the make defconfig target before
setting CONFIG_DEBUG and extra options. This fixes issues on Power where
the build fails without using the ppc64_defconfig.

Debian Stretch, Ubuntu trusty (14.04), Ubuntu xenial (16.04) and

Shawn Anastasio 2ed144aff1 automation: Switch ppc64le tests to PowerNV machine type
Run ppc64le tests with the PowerNV machine type (bare metal) instead of
the paravirtualized pseries machine. This requires a more modern version
of QEMU than is present in debian bullseye's repository, so update the
dockerfile to build QEMU from source.

Support for booting on pseries was broken by 74b725a64d ('xen/ppc:
Implement initial Radix MMU support') which resulted in CI failures. In
preparation for removing pseries support entirely, switch the CI
infrastructure to the PowerNV machine type.

Simone Ballarin 9336df4a3e automation: Add ECLAIR pipelines
Add two pipelines that analyze an ARM64 and a X86_64 build with the
ECLAIR static analyzer on the guidelines contained in Set1.

The analysis configuration is stored in automation/eclair_analysis.

All commits on the xen-project/xen:staging branch will be analyzed
and their artifacts will be stored indefinitely; the integration will
report differential information with respect to the previous analysis.

All commits on other branches or repositories will be analyzed and
only the last ten artifacts will be kept; the integration will report
differential information with respect to the analysis done on the common
ancestor with xen-project/xen:staging (if available).

Currently the pipeline variable ENABLE_ECLAIR_BOT is set to "n".
Doing so disables the generation of comments with the analysis summary
on the commit threads. The variable can be set to "y" if the a masked
variable named ECLAIR_BOT_TOKEN is set with the impersonation token of
an account with enough privileges to write on all repositories.

Additionaly any repository should be able to read a masked variable
named WTOKEN with the token provided by BUGSENG.

The analysis fails if it contains violations of guidelines tagged as
clean:added. The list of clean guidelines are maintained in
automation/eclair_analysis/ECLAIR/tagging.ecl.

By passing "gem-passthrough" as a test variant, the test will instruct

server root) as a guest dtb and to add "xen,passthrough" dtb property to
