io_uring: add support for multishot timeouts
A multishot timeout submission will repeatedly generate completions with
the IORING_CQE_F_MORE cflag set. Depending on the value of the `off'
field in the submission, these timeouts can either repeat indefinitely
until cancelled (`off' = 0) or for a fixed number of times (`off' > 0).
Only noseq timeouts (i.e. not dependent on the number of I/O
completions) are supported.
An indefinite timer will be cancelled if the CQ ever overflows.
