stuff: bz2 support, compress support, many non-required options.
now x_gzip supports "gzip -l" so sysinst should work for these platforms.
gzip will grow slightly - 400 or so bytes on x86 - but this is a small
price to pay for working -l support...
o expect the disk's start routine to return an int. If the
int is non-zero, we enqueue the request and try again
later.
o have a dk_start() routine which runs the request queue.
o have a dk_iodone() function which should be called by the
driver using the framwork from its iodone. dk_iodone will
retry the queue since presumably further progress may be
possible once a request is complete. It is required that
the underlying driver have the resources to keep at least
one transaction in flight at any time.
Modified cgd to:
o be able to keep one transaction in flight at any time
(almost) by keeping a buffer of size MAXPHYS in its softc
and use it.
We still need to make the cgd_cbufpool per device rather than global
and provide a low water mark for it.

(at least according to the submitter.)
Wolfgang Solfrank has explained the problem with router discovery
in `routed` in a way I can understand.
Let's assume that the configured preference of the interface is 5.
This gets converted to 0x80000005 through the use of the UNSIGN_PREF
macro. Later on, this value gets put into the PREF macro, which
compares it against the interface metric(s) (let's assume those
values to be 0 for now). Of course the 0x80000005, cast to int,
is much less than 0, so the clamping rule is triggered, which
gives us a value of 1. This is then converted via SIGN_PREF into
0x80000001 and put into the message. Certainly, this isn't what
was intended.
in Imake.rules:
* Allow XCOMM to be preceded by whitespace and provide a means of generating
* output lines with trailing backslashes.
* Allow XHASH to always be substituted, even in cases where XCOMM isn't.
In particular, this fixes an issue pointed out by wiz on tech-x11, where "@@"
remains unsubstituted for "\" in "startx".
This means that the tools now have correct dependencies (xxx.lo: ... instead
of xxx.o: ...) and in particular causes the pax to be built with consistent
headers.
There could also be other lossage on update builds of tools.
