This adds the large CQE support for io-uring. Large CQE's are 16 bytes longer.
To support the longer CQE's the allocation part is changed and when the CQE is
accessed.
The allocation of the large CQE's is twice as big, so the allocation size is
doubled. The ring size calculation needs to take this into account.
I'm missing something here, do we have a user for it apart
from no-op requests?
Applied, thanks!
