RAMBlock.offset --> GuestPhysBlock.target_start
RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end
RAMBlock.length --> GuestPhysBlock.target_end -
GuestPhysBlock.target_start
"GuestPhysBlock.host_addr" is only used when writing the dump contents.
This patch enables "crash" to work with the vmcore by rebasing the vmcore
from the left side of the following diagram to the right side:
host-private
offset
relative
to ram_addr RAMBlock guest-visible paddrs

Use CPUX86State instead in dump support code.

Move next_cpu from CPU_COMMON to CPUState.
Move first_cpu variable to qom/cpu.h.
gdbstub needs to use CPUState::env_ptr for now.
cpu_copy() no longer needs to save and restore cpu_next.

We should know where the note and memory is stored before writing
them to vmcore. If we know this, we can avoid using lseek() when
creating vmcore.

Dump info contains: endian, class and architecture. The next
patch will use these information to create vmcore. Note: on
x86 box, the class is ELFCLASS64 if the memory is larger than 4G.

The core file has register's value. But it does not include all registers value.
Store the cpu status into QEMU note, and the user can get more information
from vmcore. If you change QEMUCPUState, please count up QEMUCPUSTATE_VERSION.
