Create EventType for RStream reading

RStream will be the main way Neovim receives asynchronous messages, so it is
best to have a specialized EventType for it. A new flag parameter was added to
`rstream_new` which tells the RStream instance to defer event handling for later
with KE_EVENT instead of handling it directly from libuv callback.
