I have an application that creates its special registry key using
NtCreateKey(parent, "Something\0"), and then expects to be able to
open this key with NtOpenKey("Something\0") on start up. Currently
this fails because terminating '\0' in the key name doesn't survive
saving/loading the registry. parse_strW() helper already supports
loading such key names.

As the tests show after creating a kernel object with the name "Something\0"
it's possible to only open it as "Something\0", and an attempt opening it
as "Something" fails with STATUS_OBJECT_NAME_NOT_FOUND, and vice versa.
