**smaller than /24 allocations**.  Our default ruleset will not allow
those, even though they will be for various pieces of critical dual-stack
infrastructure to help IPv6-only systems survive.
This adds a default rule to allow those blocks.  With it, I see the

By default, MSVC's stdlib.h defines min(), so we need to spell out something

calls that it generates ab initio.  Eliminate direct #includes of it.  Make
sure it's a dependency of all objects (unnecessary for asm, but close enough).

which results in tame() code placements being much more recognizeable.
tame() can be moved to unistd.h and does not need cpp symbols to turn the
bits on and off.  The resulting API is a bit unexpected, but simplifies the
mapping to enabling bits in the kernel substantially.

In wsconsctl.conf configuration variables can contain doublequotes
which are removed by the shell if wsconsctl is used interactively.
In scripts, without using eval, these doublequotes are preserved
and the wsconsctl command complains about "illegal character in

Remove documentation for and instances of 'ty'. Add instances of

floppies and 'rdroot' for all boot images/miniroots.
Add 'rdroot' to dktypenames and an associated #define DTYPE_RDROOT,
since 'dt' values are parsed by matching entries in dktypenames[].
