0038ffb096 target-i386: Add API to get note's size
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.

90166b71c4 target-i386: Add API to write cpu status to core file
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.
