Hi Linus,

Changes that were queued up for this release. This pull request
contains:

- Support for recvmsg/sendmsg as first class opcodes. I don't envision
  going much further down this path, as there are plans in progress to
  support potentially any system call in an async fashion through
  io_uring. But I think it does make sense to have certain core ops
  available directly, especially those that can support a "try this
  non-blocking" flag/mode. (me)

- Handle generic short reads automatically. This can happen fairly
  easily if parts of the buffered read is cached. Since the application
  needs to issue another request for the remainder, just do this
  internally and save kernel/user roundtrip while providing a nicer more
  robust API. (me)

- Support for linked SQEs. This allows SQEs to depend on each other,
  enabling an application to eg queue a
  read-from-this-file,write-to-that-file pair. (me)

- Fix race in stopping SQ thread (Jackie)

Please pull!
