Guan Xuetao ff5928d0f2 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'

Guan Xuetao e8ede0a8bb unicore32: Split UniCore-F64 instruction helpers from helper.c
This patch just splits ucf64 instruction simulation helpers from
helper.c.
Also, two checkpatch warnings are solved.

v1->v2: adjust copyright information for new ucf64_helper.c

Guan Xuetao 527d9979b4 unicore32-softmmu: Add coprocessor 0(sysctrl) and 1(ocd) instruction support
Coprocessor 0 is system control coprocessor, and we need get/set its contents.
Also, all cache/tlb ops shoule be implemented here, but just ignored with no harm.

Coprocessor 1 is OCD (on-chip-debugger), which is used for faked console,
so we could output chars to this console without graphic card.
TODO: curses display should be added lator for screen output.

Guan Xuetao 4f23a1e645 unicore32-softmmu: Add unicore32-softmmu build support
This patch adds unicore32-softmmu build support, include configure,
makefile, arch_init, and all missing functions needed by softmmu.
Although all missing functions are empty, unicore32-softmmu could
be build successfully.
By 20120804: change QEMU_ARCH_UNICORE32 to 0x4000
