Per man 3p recvmsg, recvmsg() may return the following flags:

  MSG_EOR     End-of-record was received (if supported by the protocol).
  MSG_OOB     Out-of-band data was received.
  MSG_TRUNC   Normal data was truncated.
  MSG_CTRUNC  Control data was truncated.

Currently RecvFlags contains the flags that may be passed to recvmsg, like OOB and TRUNC, but does not contain the flags which are only received, specifically EOR and CTRUNC.

Add a new ReturnFlags type for flags returned from recvmsg
dadb095 
`RecvMsgReturn`'s `flags` field was previously `RecvFlags`, however
`recvmsg` returns a different set of flags than that. To address that,
add a new type, `ReturnFlags`, which contains the flags that are
returned from `recvmsg`.

Fixes #1287.

Makes sense. I've now submitted #1288 to implement that.
