Introduce cpu_list_generation_id to track cpu list generation so
that cpu hotplug/unplug can be detected during measurement of
dirty page rate.

cpu_list_generation_id could be used to detect changes of cpu
list, which is prepared for dirty page rate measurement.

Richard Henderson 64c8c6a992 gdbstub: Adjust gdb_syscall_complete_cb declaration 
Change 'ret' to uint64_t.  This resolves a FIXME in the
m68k and nios2 semihosting that we've lost data.

Richard Henderson 9a89470449 semihosting: Split out semihost_sys_lseek 
Split out the non-ARM specific portions of SYS_SEEK to a
reusable function.  This handles all GuestFD.  Isolate the
curious ARM-specific return value processing to a new
callback, common_semi_seek_cb.

Expand the internal type of the offset to int64_t, and
provide the whence argument, which will be required by
m68k and nios2 semihosting.

Note that gdb_do_syscall %x reads target_ulong, not int.
