Changes: added descriptions of latest stuff from David and John.

options: document now reflects the system between 1.1 and 1.2, so say
so.

-- struct ttys now allocated dynamically. (guido)
+- MCLBYTES is now 4096, so each mbuf cluster is given a whole page, in
+  preparation for page flipping.  (davidg/dyson)
+
+- More VM system improvements (dyson/davidg):
+  o Pre-faulting of initial pages on process startup and mmap (faster
+    than starting and immediately taking a fault).
+  o Even more efficient physical map (pmap) code.
+  o Pageouts are now clustered, similar to pagein clustering in 1.1.
+  o The pageout code is more efficient and keeps better statistics.
+  o The procfs can now provide more information from the VM system.
+
+- Improved IP checksum and bzero routines.  (bde/dyson)
+
+- The Mitsumi CD-ROM driver is more careful about recognizing Ethernet
+  cards as CD-ROMs.  (jkh)
+
+- `struct tty's now allocated dynamically, and ring buffers can be
+  deallocated. (guido)
