Replace valueparam with switch-bitcase in render

Changed valueparam to switch bitcase in render extension for the requests :

CreatePicture
ChangePicture

The changes of valueparam to switch has been made as per the specs for
the render extension for the possible
values of value-mask and value-list

CreatePicture :
http://cgit.freedesktop.org/xorg/proto/renderproto/tree/renderproto.txt?id=renderproto-0.11.1#n572

ChangePicture:
http://cgit.freedesktop.org/xorg/proto/renderproto/tree/renderproto.txt?id=renderproto-0.11.1#n668

The backward compatibility for the extension was checked successfully
by rendering shapes with libraries having
valueparam and then by having libraries with switch bitcase.
