o Use VOP_GETATTR() to obtain actual size of file and parse no more than that.
Previously, we parsed MAXSHELLCMDLEN characters regardless of the actual file
size. This makes the following working:
$ printf '#!/bin/echo' > /tmp/test.sh
$ chmod 755 /tmp/test.sh
$ /tmp/test.sh
Previously, attempts to execve() that shell script has been failing with bogus
ENAMETOOLONG.

- Simplify CARP_LOG() and making it working (we don't have addlog in FreeBSD).
- Introduce CARP_DEBUG() which logs with LOG_DEBUG severity when
net.inet.carp.log > 1
- Use CARP_DEBUG to log state changes of carp interfaces.
After CARP_LOG() cleanup it appeared that carp_input_c() does not need sc
argument. Remove it.

Also, treat '\0' as line terminating character, which may me useful in
some situations.

for a given device in some circumstances, so move the PDO creation
to the attach routine so we don't end up creating two PDOs.
Also, when we skip the call to ndis_convert_res() in if_ndis.c:ndis_attach(),
initialize sc->ndis_block->nmb_rlist to NULL. We don't explicitly zero
the miniport block, so this will make sure ndis_unload_driver() does
the right thing.
when we create a PDO, the driver_object associated with it is that
of the parent driver, not the driver we're trying to attach. For
example, if we attach a PCI device, the PDO we pass to the NdisAddDevice()
function should contain a pointer to fake_pci_driver, not to the NDIS
driver itself. For PCI or PCMCIA devices this doesn't matter because
the child never needs to talk to the parent bus driver, but for USB,
the child needs to be able to send IRPs to the parent USB bus driver, and
for that to work the parent USB bus driver has to be hung off the PDO.
This involves modifying windrv_lookup() so that we can search for
bus drivers by name, if necessary. Our fake bus drivers attach themselves
as "PCI Bus," "PCCARD Bus" and "USB Bus," so we can search for them
using those names.
The individual attachment stubs now create and attach PDOs to the
parent bus drivers instead of hanging them off the NDIS driver's
object, and in if_ndis.c, we now search for the correct driver
object depending on the bus type, and use that to find the correct PDO.
With this fix, I can get my sample USB ethernet driver to deliver
an IRP to my fake parent USB bus driver's dispatch routines.
- Add stub modules for USB support: subr_usbd.c, usbd_var.h and
if_ndis_usb.c. The subr_usbd.c module is hooked up the build
but currently doesn't do very much. It provides the stub USB
parent driver object and a dispatch routine for
IRM_MJ_INTERNAL_DEVICE_CONTROL. The only exported function at
the moment is USBD_GetUSBDIVersion(). The if_ndis_usb.c stub
compiles, but is not hooked up to the build yet. I'm putting
these here so I can keep them under source code control as I
flesh them out.
right for certain MAP_FIXED mappings on ia64 but it will work fine for all
other mappings and works fine on amd64.

- In kern_ndis.c:ndis_unload_driver(), test that ndis_block->nmb_rlist
is not NULL before trying to free() it.
- In subr_pe.c:pe_get_import_descriptor(), do a case-insensitive
match on the import module name. Most drivers I have encountered
link against "ntoskrnl.exe" but the ASIX USB ethernet driver I'm
testing with wants "NTOSKRNL.EXE."
- In subr_ntoskrnl.c:IoAllocateIrp(), return a pointer to the IRP
instead of NULL. (Stub code leftover.)
- Also in subr_ntoskrnl.c, add ExAllocatePoolWithTag() and ExFreePool()
to the function table list so they'll get exported to drivers properly.

- call carp_carpdev_state() on initialize instead of just setting to INIT
- in carp_carpdev_state() check that interface is UP, instead of checking
that it is not DOWN, because a rebooted machine may have interface in

uses bzero to zero out the object so there probably wont be any
real performance benefit. If UMA grows the ability to supply
zeroed zones more efficiently in the future, we will not have to
