relay: add buffer-only channels; useful for early logging
Allows one to create and use a channel with no associated files. Files
can be initialized later. This is useful in scenarios such as logging in
early code, before VFS is up. Therefore, such channels can be created and
used as soon as kmem_cache_init() completed.
This is needed by kmemtrace to do tracing in early kernel code.
