d20ebdda28 qemu: Switch to -accel
We currently use -machine accel=XXX which is just a syntax sugar
for -accel XXX. The former doesn't allow specifying arguments for
accelerator, because all arguments passed to -machine are
treated as arguments of machine itself.

The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

7bf6292fb3 qemu: always translate underscores to hyphens in CPU features
QEMU switched from using underscores in x86 CPU features to hyphens
in the 2.8.0 series with two commits

    target-i386: Remove underscores from feat_names arrays

  commit 54b8dc7c19cd781e96f1e9b001ca6001d804eb19

    target-i386: Register aliases for feature names with underscores

Libvirt names use underscores so we conditionally tranlate the
names when talking to new QEMU. Since the min QEMU was raised to
version 2.11.0, all QEMU versions we talk to expect hypens, so
the translation can be done unconditionally.

d1e48bd3db qemuxml2argvtest: Unify 'cpu-tsc-frequency' and 'cpu-tsc-high-frequency' case
Use the larger number in the original test to avoid having two files.

Additionally this avoids use of 'host-model' with DO_TEST_CAPS_LATEST in
cases when it isn't necessary for the purpose of the test as the CPU
model tends to change.

0046e0b1c2 qemuxml2argvtest: Use internal wrapping of command line arguments
virCommandToString has the possibility to return an already wrapped
string with better format than what we get from the test wrapper script.

The main advantage is that arguments for an option are always on the
same line which makes it more easy to see what changed in a diff and
prevents re-wrapping of the line if a wrapping point moves over the
threshold.

Additionally the used output is the same we have in the VM log file when
a VM is starting.

43c9c0859f qemu: use long on|off syntax for -chardev boolean option values
The preferred syntax for boolean options is to set the value "on" or
"off". QEMU 7.1.0 will deprecate the short format we currently use.

The long format has been supported with -chardev since at least 1.5.3,
so we don't need to check for it.

2de75faa28 tests: qemuxml2argv: Make use of versioned cpu-tsc-frequency and cpu-host-model-cmt tests
Commit fb973cfbb4 added versioned test outputs for the above mentioned
tests but didn't actually enable them. Fix that mistake and fix the
output of the tsc-frequency test.

fb973cfbb4 qemuxml2argvtest: Add 4.0.0 cases for kvm features tests
Newer QEMU will translate the feature names to their canonical names so
4.0.0 is the last one which produces the results we currently have in
*-latest.args.
