848696bf35 PortioList: Store PortioList in device state
PortioList is an abstraction used for construction of MemoryRegionPortioList
from MemoryRegionPortio. It can be used later to unmap created memory regions.
It also requires proper cleanup because some of the memory inside is allocated
dynamically.

By moving PortioList ot device state we make it possible to cleanup later and
avoid leaking memory.

This change spans several target platforms.  The following testcases cover all
changed lines:
  qemu-system-ppc -M prep
  qemu-system-i386 -vga qxl
  qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0

63e3e24db2 vga: add secondary stdvga variant
Add a standard vga variant which doesn't occupy any legacy
resources and thus can easily be used as secondary (or legacy-free)
graphics adapter.  Programming must be done using the MMIO bar.

e2bbfc8ee2 vga: allow non-global vmstate
Need a way to opt-out from vga.vram being global vmstate, for
secondary vga cards.  Add a bool parameter to vga_common_init
to support this.

2c62f08ddb console: simplify screendump
Screendumps are alot simpler as we can update non-active
QemuConsoles now.  So we only need to update the QemuConsole
we want write out, then dump the DisplaySurface content into
a ppm file.  Done.

No console switching needed.  No special support code in the
gfx card emulation needed.  Zap it all.  Also move ppm_save
out of the vga code and next to the qmp_screendump function.

For now screen dumping is limited to console #0 (like it used
to be), even though it is dead simple to extend it to other
consoles.  I wanna finish the console cleanup before setting
new qapi interfaces into stone.

1dbfa00503 console: rename vga_hw_*, add QemuConsole param
Add QemuConsole parameter to vga_hw_*, so the interface allows to update
non-active consoles (the actual code can't handle this yet, see next
patch).  Passing NULL is allowed and updates the active console, like
the functions do today.

While touching all vga_hw_* calls anyway rename that to the functions to
hardware-neutral graphics_hw_*
