[Qemu-devel] [PATCH 6/8] machine: rename kvm_shadow_mem to kvm-shadow-mem

[Luiz Capitulino <lcapitulino@redhat.com>]

QOM conversion wants option names with dashes. This commit does the
change for the kvm_shadow_mem machine type option.

The old option name is still supported through an option alias for
backwards compatibility.
