port addresses (even though the PC architecture doesn't support them).
Add code to limit the I/O map size based on the lowest set bit of the
address. This cures the problem with the BT946C only having a 16 bit
map register, in voiolation of the PCI specs, without giving up the
general support of >65K port regions.

Ok bruce, this is the one you were seeing..
- Optimise the linux a.out loading and uselib system calls so they
take advantage of some of John's recent interface improvements.
Basically, this means they make far less map changes than before.
- Attempt to plug some potentially nasty kernel_map memory leaks..
- Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from
the slackware 3.0 dist) but this depends on other changes to enhance
the /compat/linux support)
- uselib goes out through a single exit as part of the resource tracking
that I did when closing the resource leaks on errors. This could be
cleaner than what I did, but making a 30-deep nested if/else was not my
idea of fun, neither did I want to repeat the same code 30 times over for
each failure possibility. I guess this function needs to be split into
smaller functions to solve this.
I've been running the Linux Netscape-2.0 (with Java) to test this, and apart
from the long-standing problem with the missing scrollbars, it appears to
still work as before with ZMAGIC libs (and the leaks).. However, I've
been using it with mods for the signal trampoline code for native linux stack
frames on signals and exterminated the blasted sigreturn printf() problem,
so I can't be certain that there is not a dependency on something else.
- Clean up the access to our ifnet structure by caching a pointer
to it instead of always digging through our softc structure.

exactly as I did (should have checked there first I guess) except my
macro for TAILQ_INSERT_BEFORE took an unneeded arg. We now match 4.4Lite2.

- fill in and use ifp->if_softc
- use if_bpf rather than private cookie variables
- change bpf interface to take advantage of this
- call ether_ifattach() directly from Ethernet drivers
- delete kludge in if_attach() that did this indirectly
and rmx_recvpipe. This has no demonstrable effect on performance.
(ttcp reports about 44 Mbit/s for all the buffer sizes I tried between
16384 and 65536.)
