This method is called to set options on the stream.

### Parameters

`option`

  One of:

  - `STREAM_OPTION_BLOCKING` (The method was called in response to stream_set_blocking())
  - `STREAM_OPTION_READ_TIMEOUT` (The method was called in response to stream_set_timeout())
  - `STREAM_OPTION_WRITE_BUFFER` (The method was called in response to stream_set_write_buffer())
`arg1`

  If `option` is

  - `STREAM_OPTION_BLOCKING`: requested blocking mode (1 meaning block 0 not blocking).
  - `STREAM_OPTION_READ_TIMEOUT`: the timeout in seconds.
  - `STREAM_OPTION_WRITE_BUFFER`: buffer mode (`STREAM_BUFFER_NONE` or `STREAM_BUFFER_FULL`).
`arg2`
