All the build jobs exist in two flavors: debug and non-debug, where the
former sets 'debug' variable to 'y' and the latter to 'n'. This variable
is only being recognized by the toolstack, because Xen requires
enabling/disabling debug build via e.g. menuconfig/config file.
As a corollary, we end up building/testing Xen with CONFIG_DEBUG always
set to a default value ('y' for unstable and 'n' for stable branches),
regardless of the type of the build job.
Fix this behavior by setting CONFIG_DEBUG according to the 'debug' value.

[stefano: minor code style improvement]

Currently, all the arm64 defconfig build jobs, regardless of the
container used, end up building Xen with the extra config options
specified in the main build script (e.g. CONFIG_EXPERT,
CONFIG_STATIC_MEMORY). Because these options are only needed for
specific test jobs, the current behavior of the CI is incorrect
as we add the extra options to all the defconfig builds. This means
that on arm64 there is not a single job performing proper defconfig build.
To fix this issue, add custom build jobs each time there is a need for
building Xen with additional config options. Introduce EXTRA_XEN_CONFIG
variable to be used by these jobs to store the required options. This
variable will be then read by the main build script to modify the .config
file. This will also help users to understand what is needed to run specific
test.

Add a new test job qemu-smoke-arm64-gcc-boot-cpupools that will execute
script qemu-smoke-arm64.sh to test boot time cpupools feature.
Enable CONFIG_BOOT_TIME_CPUPOOLS for the arm64 build and add a new test
case in qemu-smoke-arm64.sh that if selected will make use of the
ImageBuilder feature to create cpupool with cpu@1, null scheduler and
assign it to domU. Add a check in dom0 xen.start to see if domU is
assigned a Pool-1 with null scheduler.
Take the opportunity to refactor the qemu-smoke-arm64.sh script as
follows:
- use domU_check to store the test's commands to be run from domU
- use dom0_check to store the test's commands to be run from dom0
- use fdtput instead of sed to perform dtb modifications
- use more meaningful messages for "passed" variable. This way we can
grep for messages reported either by domU or dom0 and get rid of
assumption that tests can only be run from domU

Enable CONFIG_STATIC_MEMORY in the existing arm64 build.
Create a new test job, called qemu-smoke-arm64-gcc-staticmem.
Adjust qemu-smoke-arm64.sh script to accomodate the static memory test as a
new test variant. The test variant is determined based on the first argument
passed to the script. For testing static memory, the argument is 'static-mem'.
The test configures DOM1 with a static memory region and adds a check in the
init script.
The check consists in comparing the contents of the /proc/device-tree
memory entry with the static memory range with which DOM1 was configured.
If the memory layout is correct, a message gets printed by DOM1.
At the end of the qemu run, the script searches for the specific message
in the logs and fails if not found.

CentOS 6 is probably the most frequently broken build, so adding it to CI
would be a very good move.
One problem is that CentOS 6 comes with Python 2.6, and Qemu requires 2.7.
There appear to be no sensible ways to get Python 2.7 into a CentOS 6
environments, so modify the build script to skip the Qemu upstream build
instead. Additionally, SeaBIOS requires GCC 4.6 or later, so skip it as well.

Currently randconfig tests are more likely to fail than to succeed
because of a bug in xen's build system: symbols-dummy.o's dependency
is wrong, which causes it to not get rebuild between runs, which
eventually causes linking to fail. There may also be other corner
cases we haven't discovered.
The fix is not straightforward. For now, make sure the tree is cleaned
properly between builds so we don't see random failures in Gitlab CI.
