a52c68443d qemu_command: Always use modern syntax of '-m'
Specify the memory size by using '-m size=2048k' instead of just '-m 2'.

The new syntax is used when memory hotplug is enabled. To preserve
memory sizing, if memory hotplug is disabled the size is rounded down to
the nearest mebibyte.

4ee4809907 qemu: validate: Fix logic for validating presence of the HPET timer
Commit 24cc9cda82 switched over to use -machine hpet, but one of the
steps it did was to clear the QEMU_CAPS_NO_HPET capability.

The validation check still uses the old capability though which means
that for configs which would explicitly enable HPET we'd report an error.

Since HPET is an x86(_64) platform specific device, convert the
validation check to an architecture check as all supported qemu versions
actually support it.

Modify a test case to request HPET to catch posible future problems.

Fixes: 24cc9cda82

0b464cd84f tests: Drop more QEMU driver config overrides
These are allegedly necessary to keep the output consistent,
but now that we're using a privileged config for the driver we
get the desired behavior out of the box, and as a bonus the
paths match what you would actually see on a regular host.

573def3a3f tests: Limit use of SPICE TLS
Follow the example of other similar settings and only enable it
for the few test cases that are actually about the specific
functionality, disabling it immediately afterwards.

A few test cases that were completely unrelated to SPICE TLS no
longer see the effects of having the feature enabled.

98c4e3d073 qemu: Use '-machine acpi=on/off' instead of deprecated '-no-acpi'
QEMU deprecated the '-no-acpi' option, thus we should switch to the
modern way to use '-machine'.

Certain ARM machine types don't support ACPI. Given our historically
broken design of using '<acpi/>' without attribute to enable ACPI and
qemu's default of enabling it without '-no-acpi' such configurations
would not work.

Now when qemu reports whether given machine type supports ACPI we can do
a better decision and un-break those configs. Unfortunately not
retroactively.

926594dcc8 qemu: Add implicit watchdog for q35 machine types
The iTCO watchdog is part of the q35 machine type since its inception,
we just did not add it implicitly.

24cc9cda82 qemu: Use '-machine hpet=off' instead of '-no-hpet'
qemu is about to deprecate the '-no-hpet' option in favor of configuring
the timer via '-machine'.

Use the QEMU_CAPS_MACHINE_HPET capability to switch to the new syntax
and mask out the old QEMU_CAPS_NO_HPET capability at the same time to
prevent using the old syntax.

697e26fac6 qemu: capabilities: Detect support for JSON args for -netdev
JSON args for -netdev were added as precursor for adding the 'dgram'
network backend type. Enable the detection and update test cases using
DO_TEST_CAPS_LATEST.

Enabling the capability also ensures that the -netdev argument is
validated against the QAPI schema of 'netdev_add' which was already
implemented but not enabled.

The parser supporting JSON was added by qemu commit f3eedcddba3 and
enabled when adding stream/dgram netdevs in commit 5166fe0ae46.
