While we're here, brucify the printf() call which happens when we
time out on acquisition of vm_page_queue_mtx.

device associated with any PCI devices that are enumerated in the ACPI
tree when adding children to an ACPI PCI bus and remove the duplicate
ACPI-only device_t and replace the device_t associated with the handle with
the ACPI and PCI aware device_t.
Several changes:
* Implement read for ulpt.
* If the device is not opened for reading, occasionally drain any
data the printer might have (but don't hammer the printer with reads).
* Lower the buffer size to one page.
The driver seems to work with more printers now.

Sorted includes.
Removed unused includes.
the SS_NBIO flag from the parent socket to the child socket during an
accept() operation.
The file descriptor O_NONBLOCK flag would have been propagated already
by the fflag assignment, and therefore would have been inconsistent
with the underlying socket's so_state member.
This makes accept() more closely adhere to the API contract we effectively
outline in the manual page. Note also that Linux continues to differ here;
O_NONBLOCK is not propagated. The other BSDs do propagate the flag, as
does Solaris. The Single UNIX Specification does not offer specific
advice on this issue.

- Split the code out into if_clone.[ch].
- Locked struct if_clone. [1]
- Add a per-cloner match function rather then simply matching names of
the form <name><unit> and <name>.
- Use the match function to allow creation of <interface>.<tag>
vlan interfaces. The old way is preserved unchanged!
- Also the match function to allow creation of stf(4) interfaces named
stf0, stf, or 6to4. This is the only major user visible change in
that "ifconfig stf" creates the interface stf rather then stf0 and
does not print "stf0" to stdout.
- Allow destroy functions to fail so they can refuse to delete
interfaces. Currently, we forbid the deletion of interfaces which
were created in the init function, particularly lo0, pflog0, and
pfsync0. In the case of lo0 this was a panic implementation so it
does not count as a user visiable change. :-)
- Since most interfaces do not need the new functionality, an family of
wrapper functions, ifc_simple_*(), were created to wrap old style
cloner functions.
- The IF_CLONE_INITIALIZER macro is replaced with a new incompatible
IFC_CLONE_INITIALIZER and ifc_simple consumers use IFC_SIMPLE_DECLARE
instead.

Only the first link0..link$NLINKS hooks would be utilized, whereas
the link hooks may be connected sparsely.
Add a counter variable so that the link hook array is only traversed
while there is still work to do, but that it continues up to the end
if it has to.
