memory: add -machine dump-guest-core=on|off
Add a new '[,dump-guest-core=on|off]' option to the '-machine' option. When
'dump-guest-core=off' is specified, guest memory is omitted from the core dump.
The default behavior continues to be to include guest memory when a core dump is
triggered. In my testing, this brought the core dump size down from 384MB to 6MB
on a 2GB guest.
Is anything additional required to preserve this setting for migration or
savevm? I don't believe so.
Changelog:
v3:
Eliminate globals as per Anthony's suggestion
set no dump from qemu_ram_remap() as well
v2:
move the option from -m to -machine, rename option dump -> dump-guest-core
