Now only stp_print_flush is exported from host script. - This patch disables irqs only for a short period of time for writing data into relayfs buffer safely. So, now each guest owns its print buffer(Stp_pbuf). - This patch also decreases the size of relay buffer of guest scripts to 128KB, because the guest scripts use relay buffer only for urgent messages. Other functions and usage are same as the previous patch. So you can test it by the previous testcase.
