97bbdc06a4 io_uring: add IORING_SETUP_SINGLE_ISSUER 
Add a new IORING_SETUP_SINGLE_ISSUER flag and the userspace visible part
of it, i.e. put limitations of submitters. Also, don't allow it together
with IOPOLL as we're not going to put it to good use.

6a02e4be81 io_uring: inline ->registered_rings 
There can be only 16 registered rings, no need to allocate an array for
them separately but store it in tctx.
