      Add thc_channel definition, update pieces of interface. · 3e525b06
      Charlie Jacobsen authored
      I realized we need to be doing the state checking in some of
      the other ipc functions (perhaps indirectly, e.g. thc_ipc_call).
      And then it seemed to make more sense to create a
      new data type - a thc channel that wraps a fipc channel with
      extras that we need when doing async stuff. So, we still do
      ref counting, but it's on the thc_channel.
      I no longer free the thc_channel when the ref drops. Leave up
      to the libasync user to decide.
      I updated the interface so that e.g. thc_ipc_recv now takes
      a struct thc_channel instead.

      Add reference counting and state to channel group items. · 8e602ced

      Motivation: thc is cooperative, but there are still cases where
      we can get into trouble. In thc_poll_recv, it's possible that
      the awe we switch to (to receive a response) wants to kill the
      channel that we just polled on. In the original implementation,
      after we scheduled that awe, we would eventually come back into
      thc_poll_recv, go to the top of the loop, and try to receive
      again; but instead, we should just abort (and in fact, we would
      be using memory after it had been freed).
      When a channel group item is created (with thc_channel_group_item_init),
      its state = LIVE, and its ref count is 1. So, the creating awe
      automatically gets a reference. When another awe wants to grab
      a reference, it should call thc_channel_group_item_inc_ref; and
      to release a reference, thc_channel_group_item_dec_ref. dec ref
      will remove the channel group item from its group and free it
      when the ref count reaches 0. To signal to other awe's (thc async
      threads) that a channel is dead, you should call
