through the use of a new build directive, MACHINE_CPU, which contains a
list of the CPU generations/features for which optimizations are desired.
This feature will be extended to cover the ports tree in the future.
Currently OpenSSL provides optimizations for i386, i586 and i686-class
CPUs. Currently it has not been tested on an i386 or i486.
Teach make(1) to provide sensible defaults for MACHINE_CPU if it is not
defined (namely, the lowest common denominator CPU we support for each
architecture). Currently this is i386 for the i386 architecture and ev4
for the alpha. sys.mk also sets the variable as a last resort for
consistency with MACHINE_ARCH and bootstrapping from very old versions of
make.
Benchmarks show a significant speed increase even in the i386 case, with
additional improvements for i586 and i686 systems. For maximum performance
define MACHINE_CPU=i686 i586 i386 in /etc/make.conf.

o Add comments in some places to clarify some points.
o Don't typedef sc_p. This isn't usually done in the drivers and may
cause problems in teh future if C goes the C++ route of requiring
one and only one definition for each and every type. Instead use
the current convetion of expanding struct ${1}_softc * inline needed.
o change some comments to be more style(9)-like.
o Define and use DEV2SOFTC to encapsulate storing/getting softc from a
dev_t. This also takes care of the missing cast from the examples.
o Define and use DEVICE2SOFTC, similar to DEV2SOFTC for getting the
softc from a device_t.

We still should have this generate foo_{isa,pci,pccard,cardbus,eisa}.c
and foovar.h from templates of some sort, but I was too lazy to do
that in this commit. I did document it in the comments, however.
Note: bde-like corrections made with the help of my my portable
plastic bde icon. Results with the real bde may vary with use.
ENABLE_SUID_SSH being defined reenable it for those that want it.
This follows discussion favoring the change from September. It
is not usually necessary to be setuid root, possibly less safe,
and less convenient (cannot use $HOSTALIASES, for example).

I have added support for finding non-PNP devices to this
sample loadable ISA driver.
PCI support will come later.
If someone with a clue about newbus were to look it over it would be
really cool.
This creates a skeleton ISA device driver.
I don't pretend that it's fully correct or even opitimal
but it at least creates (and compiles) a 'clean' ISA driver.
Hopefully PCI/PCCARD/etc. support will be added when I understand it.
Unlike the old version this just creates a module. The old one tried to
create a new kernel with the driver to be tested.
Replace all in-tree uses with necessary subset of <sys/{fb,kb,cons}io.h>.
This is also the appropriate fix for exo-tree sources.
Put warnings in <machine/console.h> to discourage use.
November 15th 2000 the warnings will be converted to errors.
January 15th 2001 the <machine/console.h> files will be removed.
