When requesting a size which cannot be read, the error message shows
a different address which is misleading to the user and it looks like
something's wrong with the address parsing. This is because the input
@addr variable is incremented in the memory dumping loop:
(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff849ffe9c specified
Fix that by saving the original address and size and use them in the
error message:
(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff8418069c/size 11534336 specified

On softmuu, instead of setting APIC ID automatically when creating a
X86CPU, require the property to be set before realizing the object
(which is already done by the CPU creation code on PC).
Keep apic_id = 0 by default on *-user so it can simply create a new CPU
object and realize it without extra steps (so target-i386 will be able
to use cpu_generic_init() eventually).

The existing apic_id = cpu_index code has no visible effect: the PC code
already initializes the APIC ID according to the topology on
pc_new_cpu(), and linux-user memcpy()s the CPU state (including
cpuid_apic_id) on cpu_copy().
Remove the dead code and simply let APIC ID to to be 0 by default. This
doesn't change behavior of PC because apic-id is already explicitly set,
and doesn't affect linux-user because APIC ID was already always 0.

listflags() had lots of unnecessary complexity. Instead of printing to a
buffer that will be immediately printed, simply call the printing
function directly. Also, remove the fbits and flags arguments that were
always set to the same value. Also, there's no need to list the flags in
reverse order.

The emulation for EEH RTAS requests from guest isn't covered
by QEMU yet and the patch implements them.
The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:
* RTAS calls are received in spapr_pci.c, sanity check is done
there.
* RTAS handlers handle what they can. If there is something it
cannot handle and the corresponding sPAPRPHBClass callback is
defined, it is called.
* Those callbacks are only implemented for VFIO now. They do ioctl()
to the IOMMU container fd to complete the calls. Error codes from
that ioctl() are transferred back to the guest.

5b79b1c "target-ppc: Create versionless CPU class per family if KVM" added
a dynamic CPU class registration with the name of the CPU family which
QEMU is running on. For example, this allowed specifying "-cpu POWER7"
on every version of POWER7 machine, not just the one which POWER7 was
an alias of. I.e. before 5b79b1c, "-cpu POWER7" would not work on real
POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8.
However that patch broke POWER5+ support as POWER5+ CPU uses the same
name as the CPU class so dynamic registering of the POWER5+ class failed.
This redefines POWER5+ server CPUs by adding a version to them and adding
an alias for TCG case. KVM will use dynamically registered CPUs.
While we are here, do the same for 970 CPU.

This patch adds basic support for the VTB.
PowerISA:
The Virtual Time Base (VTB) is a 64-bit incrementing counter.
Virtual Time Base increments at the same rate as the Time Base until its value
becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value
becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when
this occurs.
The operation of the Virtual Time Base has the following additional
properties.
1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of
the Virtual Time Base.
2. Copying the contents of a GPR to the Virtual Time Base replaces the
contents of the Virtual Time Base with the contents of the GPR.
