unicore32-softmmu: Add a minimal curses screen support
This patch adds a minimal curses screen support for unicore32-softmmu. We assume 80*30 screen size to minimize the implementation. Two problems are not solved, but they are innocuous. 1. curses windows will be blank when switching to monitor screen and back 2. backspace is not handled yet v1->v2: add extra handler for '\r' Signed-off-by: Zhang Mengchi <zhangmengchi@mprc.pku.edu.cn> Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
