Paolo Bonzini 1645b8eee5 serial: only resample THR interrupt on rising edge of IER.THRI 
There is disagreement on whether LSR.THRE should be resampled when
IER.THRI goes from 1 to 1.  Bochs only does it if IER.THRI goes from 0
to 1; PCE does it even if IER.THRI is unchanged.  But the Windows driver
seems to always go from 1 to 0 and back to 1, so do things in agreement
with Bochs, because the handling of thr_ipending was reported in 2010
(https://lists.gnu.org/archive/html/qemu-devel/2010-03/msg01914.html)
as breaking DR-DOS Plus.
