Headers in include/sysemu/ are not only related to system
*emulation*, they are also used by virtualization. Rename
as system/ which is clearer.

The oldest model that IBM still supports is the z13. Considering
that each generation can "emulate" the previous two generations
in hardware (via the "IBC" feature of the CPUs), this means that
everything that is older than z114/196 is not an officially supported
CPU model anymore. The Linux kernel still support the z10, so if
we also take this into account, everything older than that can
definitely be considered as a legacy CPU model.
For downstream builds of QEMU, we would like to be able to disable
these legacy CPUs in the build. Thus add a CONFIG switch that can be
used to disable them (and old machine types that use them by default).

As error.h suggested, the best practice for callee is to return
something to indicate success / failure.
So make kvm_s390_get_host_cpu_model() return boolean and check the
returned boolean in get_max_cpu_model() instead of accessing @err.

Printing an "s390x" in front of each CPU name is not helpful at all:
It is confusing for the users since they don't know whether they
have to specify these letters for the "-cpu" parameter, too, and
it also takes some precious space in the dense output of the CPU
entries. Let's simply remove this now!
While we're at it, use two spaces at the beginning of the lines for
the indentation of the entries, and add a "Available CPUs" in the
very first line, like most other target architectures are doing it
for their "-cpu help" output already.

some users were confused by this message showing under TCG:
Selected CPU generation is too new. Maximum supported model
in the configuration: 'xyz'
Clarify that the maximum can depend on the accel, and add a
hint to try a different one.
Also add a hint for features mismatch to suggest trying
different accel, QEMU and kernel versions.

As the comment in qapi/error, passing @errp to error_prepend() requires
ERRP_GUARD():
* = Why, when and how to use ERRP_GUARD() =
*
* Without ERRP_GUARD(), use of the @errp parameter is restricted:
...
* - It should not be passed to error_prepend(), error_vprepend() or
* error_append_hint(), because that doesn't work with &error_fatal.
* ERRP_GUARD() lifts these restrictions.
*
* To use ERRP_GUARD(), add it right at the beginning of the function.
* @errp can then be used without worrying about the argument being
* NULL or &error_fatal.
ERRP_GUARD() could avoid the case when @errp is &error_fatal, the user
can't see this additional information, because exit() happens in
error_setg earlier than information is added [1].
In target/s390x/cpu_models.c, there are 2 functions passing @errp to
error_prepend() without ERRP_GUARD():
- check_compatibility()
- s390_realize_cpu_model()
Though both their @errp parameters point to their callers' local @err
virables and don't cause the issue as [1] said, to follow the
requirement of @errp, also add missing ERRP_GUARD() at their beginning.

("error: New macro ERRP_GUARD()").
