exec: RCUify AddressSpaceDispatch
Note that even after this patch, most callers of address_space_* functions must still be under the big QEMU lock, otherwise the memory region returned by address_space_translate can disappear as soon as address_space_translate returns. This will be fixed in the next part of this series. Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
