sPAPR guests inherits the "ibm,loc-code" from the pci pass through

When rebooting the guest, some PEs might be in frozen state. The
contained PCI devices won't work properly if their frozen states
aren't cleared in time. One case running into this situation would
be maximal EEH error times encountered in the guest.
The patch reenables the EEH functinality on PEs
The PCI device MSIx table is cleaned out in hardware after EEH PE
reset. However, we still hold the stale MSIx entries in QEMU, which
should be cleared accordingly. Otherwise, we will run into another
(recursive) EEH error and the PCI devices contained in the PE have
to be offlined exceptionally.
We need communications protocol of user-defined to control the checkpoint
process.
The new checkpoint request is started by Primary VM, and the interactive process
like below:
Checkpoint synchronizing points,

tcmalloc is a malloc implementation that works well with threads and is

gcc 4.9.2 treats -nopie as an error:
cc: error: unrecognized command line option ‘-nopie’
clang 3.5.0 treats -nopie as a warning:
clang: warning: argument unused during compilation: '-nopie'
The causes ./configure to fail with clang:

QEMU does not compile cleanly under clang 3.5.0. These patches eliminate the
avalanche of warnings and make the build usable.
The result is that you *should* be able to use clang 3.5.0 *with* ccache and
-Werror and produce all targets.
Regrettably, this is v5 because I overlooked deleting "--kee

flag is supported or not.

Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.
The glib headers use GCC attributes. Unfortunately the __GNUC__ and
__GNUC_MINOR__ version macros are also defined by clang, but clang
doesn't support the same attributes as GCC.
clang 3.5.0 does not support the __alloc_size__ attribute:

It is still valid to use it for any non-QTest test cases,
which are not run for multiple target binaries.

Capture the explicit setting of "usb=no" into a separate bool, and
use it to skip the update of machine->usb in the board init function.

On sPAPR we haven't supported boot once ever since it emerged, but
recently grew need for it. This patch implements boot once logic
to it.
While at it, we also move to the new bootdevice handling that got
introduced to the tree recently.

IBM uses low 16bits to specify the chip version of a POWER CPU.
So there has never been an actual silicon with PVR = 0x003B.
The first silicon would have PVR 0x003B0100 but it is very unlikely
to find it in any machine shipped to any customer as it was too raw.

This fixes potential runtime crashes and two warnings from Coverity.
The new error message does not add a prefix "qemu:" because that is
already done in function hw_error. It also starts with an uppercase
letter because that seems to be the mostly used form.
