target-i386: fix icount processing for repz instructions
TCG generates optimized code for i386 repz instructions in single step mode.
It means that when ecx becomes 0, execution of the string instruction breaks
immediately without an additional iteration for ecx==0 (which will only check
ecx and set the flags). Omitting this iteration leads to different
instructions counting in singlestep mode and in normal execution.
This patch disables optimization of this last iteration for icount mode
which should be deterministic.

abort() has the sometimes undesirable side-effect of generating a core
dump. If that is not needed, SIGKILL has the same effect of abruptly
crash qemu; without a core dump.

block: vhdx - change .vhdx_create default block state to ZERO
The VHDX spec specifies that the default new block state is
PAYLOAD_BLOCK_NOT_PRESENT for a dynamic VHDX image, and
PAYLOAD_BLOCK_FULLY_PRESENT for a fixed VHDX image.
However, in order to create space-efficient VHDX images with qemu-img
convert, it is desirable to be able to set has_zero_init to true for
VHDX.
There is currently an option when creating VHDX images, to use block
state ZERO for new blocks. However, this currently defaults to 'off'.
In order to be able to eventually set has_zero_init to true for VHDX,
this needs to default to 'on'.
This patch changes the default to 'on', and provides some help
information to warn against setting it to 'off' when using qemu-img
convert.
[Max Reitz pointed out that a full stop was missing at the end of the
VHDX_BLOCK_OPT_ZERO option help text. I have added it.

The 0.95 VHDX spec defined PAYLOAD_BLOCK_UNMAPPED to be 5. The 1.00

The original value of 5 is now an undefined state in the spec, but it
should be safe to treat it the same and return zeros for data read.
This way, we can maintain compatibility with any images out in the wild
that may have been created in accordance to the 0.95 spec.

target-arm/kvm: make reg sync code common between kvm32/64
Before we launch a guest we query KVM for the list of "co-processor"
registers it knows about. This is used to synchronize system
register state for the bulk of coprocessor/system registers.
Move this code from the 32-bit specific vcpu init function into
a common routine and call it also from the 64-bit vcpu init.
This allows system registers to migrate correctly when using
KVM, and also permits QEMU code to see the current KVM register
state (which will be needed to support big-endian guests, since
the virtio endianness callback must check for some system register
settings).
Since vcpu reset also has to sync registers, we move the
32 bit kvm_arm_reset_vcpu() into common code as well and
share it with the 64 bit version.

[PMM: just copy the 32-bit code rather than improving it along the way;

- A32_BANKED_CURRENT macros are used for choosing the banked register based on

Add the "-semihosting-config" option.
The usual semihosting behaviour is to process the system calls locally and
return; unfortuantelly the initial implementation dinamically changed the
target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb,
is not implemented. The result was that during debug sessions the semihosting
calls were discarded.
This patch adds a configuration variable and an option to set it on the
command line:
-semihosting-config [enable=on|off,]target=native|gdb|auto
This option enables semihosting and defines where the semihosting calls will
be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which
means 'gdb' during debug sessions and 'native' otherwise.
