patch and testcase

With this patch, stap can support $$vars or $$parms for kernel marker. 
For example in FC11.

$ stap -l 'kernel.mark("ext4_da_writepage")'
kernel.mark("ext4_da_writepage").format("dev %s ino %lu page_index %lu")

$ stap -e 'probe kernel.mark("ext4_da_writepage") { printf("%s\n",$$parms)}'
