hw/xen: add stubs for various functions

Those symbols are used by system/physmem.c, and are called only if
xen_enabled() (which happens only if CONFIG_XEN is set and xen is
available).

So we can crash the stubs in case those are called, as they are linked
only when CONFIG_XEN is not set.

rust/hpet: Fix a clippy error

Carge clippy complained about:

error: casts from `u8` to `u32` can be expressed infallibly using `From`

So use `From` to convert `u8` to `u32`.

rust/hpet: convert HPETTimer index to u8 type

The C version of HPET uses the uint8_t type for timer index ("tn"), and
usize type in Rust version will break migration between the C and Rust
versions.

So convert HPETTimer index' type to u8 (consistent with the C version of
HPET) to make it friendly for vmstate support.

rust/hpet: convert num_timers to u8 type

The C version of HPET uses the uint8_t type for num_timers, and usize

Note the commit 7bda68e8e2b0 ("qdev, rust/hpet: fix type of HPET

property has to be re-supported now.

docs/devel/testing: Dissolve the ci-definitions.rst.inc file

This file was meant for defining the vocabulary for our testing
efforts, but it did not age well: First, the definitions are not
only about the CI part, but also about testing in general, so most
of the information should rather reside in main.rst instead.
Second, some vocabulary has never been really adopted by the QEMU
project, for example we never really use the word "system testing"
since "system" rather means the system emulator binaries in the
QEMU project (and we also don't do any testing with other components
like libvirt and virt-managers here). It also defines that the qtests
are the "functional" tests in QEMU, which is not really up to date
anymore after the "tests/functional" framework has been introduced
a couple of months ago (FWIW, the qtests could rather be seen as a
mix between unit testing and functional testing).

To solve this problem, move the useful parts of this file into
main.rst and directly into ci.rst, and drop the ones (like "system
testing") that we don't really need anymore.

gitlab-ci: Update QEMU_JOB_AVOCADO and QEMU_CI_AVOCADO_TESTING

Since we don't run the Avocado jobs in the CI anymore, rename
these variables to QEMU_JOB_FUNCTIONAL and QEMU_CI_FUNCTIONAL.

Also, there was a mismatch between the documentation and the
implementation of QEMU_CI_AVOCADO_TESTING: While the documentation
said that you had to "Set this variable to have the tests using the
Avocado framework run automatically", you indeed needed to set it
to make the pipelines appear in your dashboard - but they were never
run automatically in forks and had to be triggered manually. Let's
improve this now: No need to hide these pipelines from the users
by default anymore (the functional tests should be stable enough
nowadays), and rather allow the users to run the pipelines auto-
matically with this switch now instead, as was documented.

tests/functional: Convert the SMMU test to the functional framework

This test was using cloudinit and a "dnf install" command in the guest
to exercise the NIC with SMMU enabled. Since we don't have the cloudinit
stuff in the functional framework and we should not rely on having access
to external networks (once our ASSETs have been cached), we rather boot
into the initrd first, manually mount the root disk and then use the
check_http_download() function from the functional framework here instead
for testing whether the network works as expected.

Unfortunately, there seems to be a small race when using the files
from Fedora 33: To enter the initrd shell, we have to send a "return"
once. But it does not seem to work if we send it too early. Using a
sleep(0.2) makes it work reliably for me, but to make it even more
unlikely to trigger this situation, let's better limit the Fedora 33
tests to only run with KVM.

Finally, while we're at it, we also add some lines for testing writes
to the hard disk, as we already do it in the test_intel_iommu test.

so most of these Avocado tests have either been disabled by default

We won't include this sluggish cloudinit stuff in the functional
