constify struct cfattach

Replace ancient DELAY inherited from Mach and the associated scary
comment with a barrier. Tested in both fast and slow modes.

Get rid of evcount's support for arranging counters in a tree
hierarchy. Everything attached to a single root node anyway, so at
best we had a bush.

Pass a device name to {tc,tcds,ioasic}_intr_establish in order to get
meaningful names associated to the interrupt counters.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Get rid of TC_IPL_xxx values and tc_intrlevel_t, and use IPL_xxx and int.
No functional change.

Use new event counter API for interrupt counting on alpha. By me, with some
edits by Theo. deraadt@ ok

Typos: defintion -> definition, proccess -> process

There are more occurences hiding in binutils, lynx and afs but I am too
lazy to report them upstream at the moment.

Remove more '\n's from panic() statements. Both trailing and leading.

Big TURBOchannel support catchup from NetBSD, part 1.
A few local changes and tweaks remain.

This bring DEC 3000 machines back in the game, but framebuffers are still
not supported at the moment.

Thanks to ericj@ and nate@ for supplying me a DEC 3000 for testing.
