ppc patch queue 2017-10-17

Here's the currently accumulated set of ppc patches for qemu.

  * The biggest set here is the ppc parts of Igor Mammedov's cleanups
    to cpu model handling
  * The above also includes a generic patches which are required as
    prerequisites for the ppc parts.  They don't seem to have been
    merged by Eduardo yet, so I hope they're ok to include here.
  * Apart from that it's basically just assorted bug fixes and cleanups

Commit "3d90c625 vga: stop passing pointers to vga_draw_line*
functions" is incomplete.  It doesn't handle the case that the vga
rendering code tries to create a shared surface, i.e. a pixman image
backed by vga video memory.  That can not work in case the guest display
wraps from end of video memory to the start.  So force shadowing in that
case.  Also adjust the snapshot region calculation.

Can trigger with cirrus only, when programming vbe modes using the bochs
api (stdvga, also qxl and virtio-vga in vga compat mode) wrap arounds
can't happen.

In order to prevent the guest from forcing the allocation of large amounts
of qemu memory (or host kernel memory, in the case of KVM HV), we limit
the size of Hashed Page Table (HPT) it is allowed to allocated, based on
its RAM size.

However, the current calculation is not correct: it only adds up the size
of plugged memory, ignoring the base memory size.  This patch corrects it.

While we're there, use get_plugged_memory_size() instead of directly
calling pc_existing_dimms_capacity().  The only difference is that it
will abort on failure, which is right: a failure here indicates something
wrong within qemu.

use common cpu_model prasing in vl.c and set default cpu_model
using generic MachineClass::default_cpu_type.

Beside of switching to generic infrastructure it solves several
issues.

 * ppc_cpu_class_by_name() is used to deal with lower/upper case
   and alias translations into actual cpu type, which fixes
    '-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0'
   usecases which error out with:
    'invalid CPU model 'FOO' for powernv machine'
 * allows to switch to lower-case typenames in pnv chip/core name
   (by convention typnames should be lower-case)
 * replace aliased names /power8, power9, .../ with exact cpu model
   names (i.e. typenames should be stable but aliases might decide to
   point to other cpu model withi family or changed by kvm). It will
   also help to simplify pnv_chip/core code and get rid of dependency
   on cpu_model parsing.
