x11/mlterm: Add support for 8-/4-bpp planar fb found on NetBSD/amiga.

Requires amidisplaycc(4) driver from NetBSD-current. With older
drivers, automatically falls back to monochrome mode.

Bump revision.

+Add support for 8- and 4-bpp planar fb found on NetBSD/amiga.
+
+Requires amidisplaycc(4) driver from NetBSD-current. With older
+drivers, automatically falls back to monochrome mode.
+
+XXX
+Only tested for 8-bpp mode. As 4-bpp mode requires ancient
+analogue monitors.
+
+XXX
+Logic to detect planar fb is not very elegant...
+
+This has been pull-requested to upstream:
