update (master)
xenocara xlock uses imsg for privsep.
What changes: - imsg_init becomes imsgbuf_init but imsgbuf_init can now fail - Adding imsgbuf functions to hide the msgbuf functions: msgbuf_clear -> imsgbuf_clear msgbuf_write -> imsgbuf_write - Also rename imsg_read to imsgbuf_read. - Both imsgbuf_read and imsgbuf_write have simplified error handling. imsgbuf_write now returns 0 on success so that old wrong connection closed check must be removed - Remove now official ibuf_get_string() OK tb@ matthieu@
