Description of problem:
SDL and curses has been disabled default, but still in qemu-doc. If qemu-kvm will not support it should remove it from qemu-doc.

Version-Release number of selected component (if applicable):

Host:
qemu-kvm-1.5.3-31.el7.x86_64

How reproducible:
100%

Steps to Reproduce:

1.Start qemu-kvm with sdl/curses option.
[root@localhost ~]# /usr/libexec/qemu-kvm -monitor stdio -display sdl
SDL support is disabled
[root@localhost ~]# /usr/libexec/qemu-kvm -monitor stdio -display curses
Curses support is disabled
[root@localhost ~]# /usr/libexec/qemu-kvm -monitor stdio -sdl
SDL support is disabled
[root@localhost ~]# /usr/libexec/qemu-kvm -monitor stdio -curses
Curses support is disabled

2.Check qemu-kvm manual.
man qemu-kvm
...
       -display type
           Select type of display to use. This option is a replacement for the old style -sdl/-curses/... options. Valid values for type are

           sdl Display video output via SDL (usually in a separate graphics window; see the SDL documentation for other possibilities).

           curses
               Display video output via curses. For graphics device models which support a text mode, QEMU can display this output using a curses/ncurses interface. Nothing is
               displayed when the graphics device is in graphical mode or if the graphics device does not support a text mode. Generally only the VGA device models support text
               mode.

Expected results:
Remove sdl/curses from qemu-doc.
