   Fix merge error during last update.

   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()

   Update to libXi 1.8.2.

   The fix for double alignment on 32bits machines with strict constraints
   was already committed.

   Update to libXfont2 2.0.7

   Update to xserver 21.1.14. tested by tb@

   The xkb security fix was committed earlier. This is the rest of the
   21.1.14 update.

   Don't log DDC modelines (after hotplug events/xrandr) or "Using XX ranges
   from config file" messages. These were printed after hotplug events which
   could be frequent in some cases (I have machines where this happens every
   10 seconds when the monitor is in a dpms power-saving mode resulting in a
   full /var/log filesystem).

   EDID vendor/product ID still logged, giving an indication that events are
   happening, but reduced from ~3.5KB per event to <100 bytes.

   xkb: Fix buffer overflow in _XkbSetCompatMap()

   The _XkbSetCompatMap() function attempts to resize the `sym_interpret`
   buffer.

   However, It didn't update its size properly. It updated `num_si` only,
   without updating `size_si`.
