Clear pollin flag when input buffer is flushed
...
The pollin flag must be cleared when the input buffer (pty slave) is
flushed. This ensures that the POLLIN event is not signaled to the application,
when there is not data to read.

Don't clear readable flag on poll
...
When the slave becomes readable we set the pollin flag, and cleared it
in ttynvt_poll().
So if ttynvt_poll() is called twice, the readable flag was lost.
Now we clear it in ttynvt_read() if there actually are no more data to
be read.

ICS-664: Fix "cu problem"
...
In ttynvt_read(), the "interrupted" signal may be delivered after
installing the handler (fuse_req_interrupt_func()) but before calling
read().
If this happens the signal intended to be delivered while in the read()
function call (SIGUSR2) is handled before the read(), and we may hang
indefinitely.
