Fixes to PacketMMap dispatcher.

This CL fixes the following bugs:

- Uses atomic to set/read status instead of binary.LittleEndian.PutUint32 etc
which are not atomic.

- Increments ringOffsets for frames that are truncated (i.e status is
  tpStatusCopy)

- Does not ignore frames with tpStatusLost bit set as they are valid frames and
  only indicate that there some frames were lost before this one and metrics can
  be retrieved with a getsockopt call.

- Adds checks to make sure blockSize is a multiple of page size. This is
  required as the kernel allocates in pages per block and rejects sizes that are
  not page aligned with an EINVAL.

Updates #210
