prediction code. Previously, 2GB worth of header predicted data
could leave these variables too far out of sequence which would cause
problems after receiving a packet that did not match the header
prediction.

HUGE_VAL is not properly aligned on some architectures. The previous
fix now works because the two versions of 'math.h' (include/math.h
and lib/msun/src/math.h) have since been merged into one.

This is NOT YET CONVERTED TO -current.
This node is a source for preprogrammed packets at a known rate for testing.
I will convert it to -current "in place" but will MFC teh original
pre-conversion variant as that is what is originally submitted.

nfsm_srvpathsiz. This macro plucks a length out of an rpc request and
verifies that its size does not exceed NFS_MAXPATHLEN. If it does
it generates an ENAMETOOLONG response.
- Use this macro, and the existing nfsm_srvnamsiz macro in two places
where we deal with paths passed in by the client.
This fixes a linux interoperability bug. Linux was sending oversized path
components which would cause us to ignore the request all together. This
causes linux to hang indefinitly while it waits for a response. This
could still happen in other cases where we error out with EBADRPC.

In some ACPI BIOS implementations, boot disabled devices don't have
ACPI_STA_ENABLE bit in _STA object.
Also it is not fatal if getting current IRQ of boot disabled devices
is failed in initial state.
And minor fixes.

across system suspends on the Intel 82371AB PCI-ISA bridge. On a
Sony Vaio C1XD that I have, these registers are not set correctly
after an ACPI resume. The result is that after resuming, a shared
IRQ is left in edge-triggered mode so the interrupt can later become
jammed in a state where the line remains asserted, but the handler
is never called.

behaviour of the hardware: a possibly reserved bit of the receive
descriptor (RFA) `status' field is borrowed to record no-resource
(RNR) events, and the same status field is read and written to at
a time that may clash with the hardware updating this field.
There is no hardware documentation available to determine if these
things are safe to do; the second issue almost certainly isn't, and
the first is only safe if there is documentation saying that this
bit is free to be used by the driver. The PR referenced below
provides extremely convincing evidence that the changes cause random
crashes on some (unusual) hardware.
Since these features are only required by the DEVICE_POLLING case,
this commit makes their use conditional on that option. It does not
change the DEVICE_POLLING case, but at least people with the rare
hardware on which this code causes problems can now avoid the crashes
by not enabling DEVICE_POLLING.
