dump: rebase from host-private RAMBlock offsets to guest-physical addresses

RAMBlock.offset --> GuestPhysBlock.target_start
RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end

s390x/kvm: Remove redundant return code

Removed the redundant return code statement from handle_instruction() - it
always returned 0 and never reports any errors to its caller, since errors
from the sub-functions are already reported via program exceptions instead....

s390: Implement dump-guest-memory support for target s390x

With this patch dump-guest-memory on s390 produces an ELF formatted,
crash-readable dump.
In order to implement this, the arch-specific part of dump-guest-memory
was added:
target-s390x/arch_dump.c contains the whole set of function for writing...

s390x/kvm: Reworked/fixed handling of cc3 in kvm_handle_css_inst()

Consolidated the setting of the condition code in kvm_handle_css_inst().
For the (unhandled) instructions EQBS and SQBS, we have to return
an operation exception instead of cc3. Also removed the is_ioinst()...

s390x/ioinst: Fixed alignment check in SCHM instruction

full page boundary.

s390x/ioinst: Fixed priority of operand exceptions

Operand exceptions have a lower priority than specification and address
exceptions. Thus the checks for operand exceptions must be done later.

s390x/ioinst: Add missing alignment checks for IO instructions

The IO instructions MSCH, SSCH, STSCH, TSCH, STCRW and TPI require
that the second operand address must be aligned on a word boundary.

s390x/ioinst: Throw addressing exception when memory_map failed

So far, the IO instructions were throwing specification exceptions when
there was a problem with accessing the memory. However, the better way
is to throw an addressing exception instead.

s390x: Rename 'dprintf' to 'DPRINTF'

'dprintf' is the name of a POSIX standard function so we should not be
stealing it for our debug macro. Rename to 'DPRINTF' (in line with
a number of other source files.)

cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".

The reason for the failure is that CPUClass::kvm_fd is not yet...
