Now that we have a hard dependency on python anyway, we can replace the
slow shell script to calculate the option ROM checksum with a fast AND
portable python version. Tested both with python 2.7 and 3.1.

tb.time is a time value, but not necessarily of the same size as time_t:
while time_t is 64 bit for w64, tb.time still is 32 bit only.
Therefore we need en explicit conversion.

Replace all type casts to 'long' or 'unsigned long' by 'intptr_t' or 'uintptr_t'.
For type casts which are only used to extract the lower bits of an address
or to modify those bits, signedness does not matter. There I always use 'uintptr_t'.

The default definition of setjmp which is implemented in MinGW-w64
cannot be used with programs like QEMU which call longjmp from
code without structured exception handling (SEH).
This code therefore disables stack unwinding.
We could also implement SEH for QEMU's generated JIT code, but
that is much more difficult. Stack unwinding would also cost
execution time.

w64 uses the registers rcx, rdx, r8 and r9 for function arguments,
so it needs a different declaration of tcg_target_call_iarg_regs.
rax, rcx, rdx, r8, r9, r10 and r11 may be changed by function calls.
rbx, rbp, rdi, rsi, r12, r13, r14 and r15 remain unchanged by function calls.

Currently, the PAPR VIO network device does not have a reset handler. This
means that after a hard reset, H_REGISTER_LOGICAL_LAN will return an error
when the new guest boot attempts to initialize the device.
This patch corrects this, adding a suitable reset hook.

On the pseries platform, access to PCI config space is via RTAS calls(
which go to the hypervisor) rather than MMIO. This means we don't use
the same code path as nearly everyone else which goes through pci_host.c
and we're missing some of the parameter checking along the way.
We do have some parameter checking in the RTAS calls, but it's not enough.
It checks for overruns, but does not check for unaligned accesses,
oversized accesses (which means the guest could trigger an assertion
failure from pci_host_config_{read,write}_common(). Worse it doesn't do
the basic checking for the number of RTAS arguments and results before
accessing them.
This patch fixes these bugs.

On target-ppc, our table of CPU types and features encodes the features as
found on the hardware, regardless of whether these features are actually
usable under TCG or KVM. We already have cases where the information from
the cpu table must be fixed up to account for limitations in the emulation
method we're using. e.g. TCG does not support the DFP and VSX instructions
and KVM needs different numbering of the CPUs in order to tell it the
correct thread to core mappings.
This patch cleans up these hacks to handle emulation limitations by
consolidating them into a pair of functions specifically for the purpose.

Currently the pseries machine contains not one but two somewhat ugly hacks
to allow printing of early debug messages before the guest has properly
read the device tree.
First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually
invalid) will look for a suitable vty and use that. This supports Linux's
early debug code which will use H_PUT_TERM_CHAR with vtermno==0 before
reading the device tree. Second, we support the RTAS display-character call.
This takes no vtermno so we assume the address of the default first VTY.
This patch makes things more consistent by folding the second hack into the
first. Now, display-character uses the existing vty_lookup() function to
do the same search for a suitable VTY.

Commit 41557447d30eeb944e42069513df13585f5e6c7f also introduced a subtle TLB
flush bug. By applying a mask to the interrupt MSR which cleared the IR/DR
bits at the start of the interrupt handler, the logic towards the end of the
handler to force a TLB flush if either one of these bits were set would never
be triggered.
This patch simply changes the IR/DR bit check in the TLB flush logic to use
the original MSR value (albeit with some interrupt-specific bits cleared) so
that the IR/DR bits are preserved at the point where the check takes place.
