update to version of May 19, 1997
Use the generic root/swap in the model-specific configuration files.
Include pm_ds.c if pm_ds, not dc_ds - dc_ds gets set for the 5000/200 as
well as the 3100, but trying to include pm_ds.c for a 5000/200-only
configuration fails.
make Jazz16 16-bit output work properly again.  Still hangs somewhere
(not yet diagnosed) on occasion in high-speed mode, but a ^C will exit
immediately--no 30-second drainage timeout.
fix popping noises on 16-bit ulinear output.
add big-endian support
XXX ULINEAR_BE still needs ad1848 emulation on gusmax
fix typo
fix typos; from Paul Goyette in PR bin/3676
* don't log failed usernames to ftp.notice; use authpriv.notice instead.
  closes [bin/1571]
* don't quit if "PASV" is received without the user being logged in.
  closes [bin/2401], albiet with a modified test.
Add a cleandir to make build, to make it more like it was before.
These makefiles need to include bsd.own.mk early-on so that they
know BUILDDIR and OBJDIR.
Fix pr#3679 a little different.
Remove the '-nostdlib' flag for ELF systems and keep it for a.out systems.
Remove the install: line and use FILES and FILESDIR.
Use movw when loading countdown registers.
If BUILDDIR is the same as DESTDIR, we aren't really using an object
file tree, so undef OBJDIR and install includes, etc. the old way.
Also, don't use OBJDIR at all if we're not under BSDSRCDIR.
Fix possible uninitialized variable bug which trips -Wall.  When
recovering from a possible race condition in sii_intr, read the active
target from the destat register, and set the softc state pointer
`state' appropriately.  (This warning is in a block that prints a
warning message, and the warning message has _never_ been seen. The
bug is probably innocuous.)

Also addresses the `more thought needed' in the log message for rev. 1.12.
Forgot to quote a variable.
Quote it properly this time.
Add rcmd to the SUBDIR list.
Add ./bin/rcmd
Add inline definitions for _getsr() and _splraise(), and
define splimp() using splraise so early calls to the VM
code (and pmap) do not accidently enable interrupts.
