improve scroll_up perf
...
We were marking the entire scrollback history as dirty on each line
scroll. This was from the early days and isn't needed any more.
This brings the runtime of:
```
$ find /usr > /tmp/usr-files.txt
$ time cat /tmp/usr-files.txt
```
down from ~2.5s to ~1.2s.
Also avoid a redundant line_mut() call in set_cell().

Don't loop to read from pty
...
We don't need to be greedy in handling this read. It is important
not to for example when a lot of data is being written to the pty
we don't want that to starve the gui event handler and block sending
an interrupt signal.
