Wez Furlong 693a717db2 improve output parsing performance and throughput
I've been meaning to do this for a while; this commit moves
the escape sequence parsing into the thread that reads the
pty output which achieves two goals:

* Large escape sequences (eg: image protocols) that span multiple
  4k buffers can be processed without ping-ponging between the
  reader thread and the main gui thread
* That parsing can happen in the reader thread, keeping the gui
  thread more responsive.

These changes free up the CPU during intensive operations such
as timg video playback.

This is a slight layering violation, in that this processing
really belongs to local pane (or any pane that embeds Terminal),
rather than generically at the Mux layer, but it's not any
worse a violation than `advance_bytes` already was.
