Hi,

One of the things we currently cannot do with direct descriptors is pass
it to another application or ring. This adds support for doing so, through
the IORING_OP_MSG_RING ring-to-ring messaging opcode.

Changes since v1:
- Add IORING_MSG_RING_CQE_SKIP flag for IORING_OP_MSG_RING
- Expand commit message in patch 2

Some unresolved questions in patch 2 that need debating.
