they aren't in the usual path of execution for syscalls and traps.
The main complication for this is that we have to set flags to control
ast() everywhere that changes the signal mask.
Avoid locking in userret() in most of the remaining cases.

inline function sigsetmasked() and a new macro SIGPENDING(). CURSIG()
will soon be moved out of the normal path of execution for syscalls and
traps. Then its efficiency will be less important but the new interfaces
will be useful for checking for unmasked pending signals in more places.

Assert that sched_lock is not held in CURSIG().
o OpenBSD's wiconfig tells me that a value of '2' is for sony wireless
cards, 1 is for lucent (which we already knew) and '5' is for embedded
lucent cards.
o Move some RID definitions to if_wavelan_ieee.h and use NetBSD names
more often.

interrupts. This is a bit harder than it needs to be because there's
more than one way to generate link attentions, at least one of which
does not work on the BCM5700, but does on the 5701.
For the 5701, we can safely use the 'link changed' bit in the status
block, and we enable link change attentions in the mac event register.
For the 5700, we have to use MII interrupts, which require checking
the MAC status register rather than the status block. This requires
doing an extra register access on each interrupt which I'd prefer to
avoid, but them's the breaks. Testing with both a 3c996-T and 3c996B-T
shows that we do in fact detect the link going up and down properly
on cable insertions/disconnections.
Also, avoid twiddling the autopoll enable bit in the MI mode register
when doing a PHY read. I think this coupled with the other changes
will stop the interrupt storms Paul Saab has been harassing me about.
Manually setting the link to 100baseTX full duplex seems to work ok
for me. (I'm typing over the 3c996B-T right now.)
Lastly, teach the driver how to recognize a 3c996B-SX by checking
the hardware config word in the EEPROM in order to detect the media.
We attach 5701 fiber cards correctly now, but I haven't verified that
they send/receive packets yet since I don't have a second fiber
interface at home. (I know that fiber 5700 cards work, so I'm
keeping my fingers crossed.)
<strings.h>, based on POSIX.1-2001's requirements.
o Add 'restrict' qualifier (spelled '__restrict') to functions in
<string.h>, as per C99 and POSIX.1-2001.
o Properly expose new POSIX.1-2001 functions in <string.h>.
This driver was written by Myson and is made available
by their courtesy.
The 5.x version is not fully tested (I will be testing) but
the 4.x version has been tested by many.
I will commit it soon.
Myson have their own chip design based on the DEC 214xx family but
with several differences. Myson sells this chip to several
EOMs in teh Chinese area so there may be many noname brand cards
that respond to this driver. Myson will be supplying a list
of some of these.
We get enough protection from the lock on the individual lists that we
aquire later.

1) Properly detect the Symbol based cards (The 3Com Airconnect and their
ilk) and only reset them *ONCE* ever. This appears to make them work,
but more testing is needed. The tests that would wedge up my machine
completely now appear to work, but I have not real access points
handy.
2) Report both the Station firmware and the Primary firmware on Prism
based cards. On Lucent based cards, only report the station firmware
since that's all it supports. On symbol cards, report the symbol
specific firmware name as its station firmware.
3) Better Prism 2.5 and 3 family names. We really need to go table
driven for this.
4) Workaround for bugs in Intersil's firmware is only needed for at most
0.8.2 and earlier, since 0.8.3 and later appear to work.

Unfortunately, this level doesn't really provide enough granularity. We
probably need several MI NOTES type files for things that are shared by
several architectures but not by all. For example, the PCI options could
live in a NOTES.pci.
This also updates the Makefile for i386 to generate LINT. The only changes
in the generated LINT are the order of various options.
Suggestions for improvement welcome.
