Added parameter to take screenshot with screendump as PNG

Currently screendump only supports PPM format, which is un-compressed. Added
a "format" parameter to QMP and HMP screendump command to support PNG image
capture using libpng.

QMP example usage:
{ "execute": "screendump", "arguments": { "filename": "/tmp/image",
"format":"png" } }

HMP example usage:
screendump /tmp/image -f png
