Also minor cleanup of dependencies in conf/files that I bogusly added
before.
This should fix the requirement that make depend be done starting from
a clean config directory. If you don't have a clean directory, make
depend is still required if you want the proper .o's to be recompiled.

with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

during a trek through RCS. The Macronix 98713 and 98713A both have the
same PCI device ID but different revision numbers, and we need to be
able to tell one from the other. The 98715 and 98715A chips have the
same device ID as the 98725 chip but different revision numbers, however
we lump them into the same category except when identifying them during
the PCI probe output.
The main reason we need tell the chips apart is that the Macronix app
notes say you have to write a special magic number into one of the
registers in order to put the chip in normal operating mode. The 98713
requires one magic value, while all the others require a different one.

alpha, operations involving non-finite numbers or denormalised numbers
or operations which should generate such numbers will cause an arithmetic
exception. For programs which follow some strict code generation rules,
the kernel trap handler can then 'complete' the operation by emulating
the faulting instruction.
To use software completion, a program must be compiled with the arguments
'-mtrap-precision=i' and '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'.
Programs compiled in this way can use non-finite and denormalised numbers
at the expense of slightly less efficient code generation of floating
point instructions. Programs not compiled with these options will receive
a SIGFPE signal when non-finite or denormalised numbers are used or
generated.

Add ICMP_BANDLIM option and 'net.inet.icmp.icmplim' sysctl. If option

to 0 will disable the feature. This feature limits ICMP error responses
for packets sent to bad tcp or udp ports, which does a lot to help the
machine handle network D.O.S. attacks.
The kernel will report packet rates that exceed the limit at a rate of
one kernel printf per second. There is one issue in regards to the
'tail end' of an attack... the kernel will not output the last report
until some unrelated and valid icmp error packet is return at some
point after the attack is over. This is a minor reporting issue only.

with the field pointer pointing to byte 9 of a 6 byte CDB.
In any case, the work around is to put in a quirk mechanism that makes sure
that we don't send 6-byte reads or writes to this device. It's rather sad
that this is necessary. You'd think that they would be able to get
something that basic to work right in their firmware...

problem is worked around by using an interrupt gate for the page
fault handler. This code was originally made for NetBSD/pc98 by
Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp> and has already
been in PC98 tree. Because of this bug, trap_fatal cannot show
correct page fault address if %cr2 is obtained in this function.
Therefore, trap_fatal uses the value from trap() function.
- The trap handler always enables interruption when buggy application
or kernel code has disabled interrupts and then trapped. This code
was prepared by Bruce Evans <bde@FreeBSD.org>.

Setting the alternate method (sysctl -w kern.timecounter.method=1)

I decided to NOT have the "calcru" change the method automatically
because you should be aware of this problem if you have it.
The problems currently seen, related to usleep and a few other corners
are fixed for both methods.
