[Qemu-devel] [PATCH 3/4] console: pass Monitor to vga_hw_screen_dump/hw_vga_dump

[Alon Levy <alevy@redhat.com>]

Passes the Monitor ptr to the screendump implementation to all for
monitor suspend and resume for qxl to fix screendump regression.

graphics_console_init signature change required touching every
implemented of screen_dump. There is no change other then an added
parameter. qxl will make use of it in the next patch.

compiles with ./configure
