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()
