Re-read terminal attributes after applying them.

Browse Source 
After applying settings to a terminal device, in functions term_reset(),
term_replace(), and term_apply(), re-read the setting from the device in
order to update "currtermios", "nexttermios", and "origtermios" as
required. Do not assume that the settings applied are the ones
effectively set to the device (some of them may be ignored, or changed
by the kernel or the driver).
