attempting to change the BPF filter on a BPF descriptor at the same
time: retrieve the old filter pointer under the same locked region
as setting the new pointer.

- Use our loop DLT type, not OpenBSD. [1]
- The fields that are converted to network byte order are not 32-bit
fields but 16-bit fields, so htons should be used in htonl. [1]
- Secondly, ip_input changes ip->ip_len into its value without
the ip-header length. So, restore the length to make bpf happy. [1]
- Use bpf_mtap2(), use temporary af1, since bpf_mtap2 doesn't
understand uint8_t af identifier.

yet I only changed one of them. So when we loaded drivers, we'd fail
to allocate resources correct.
This pointed out that we were doing the wrong thing when we failed to
attach a child. We released all the resources and almost deleted the
child. Instead, we should keep the resources allocated so when/if a
driver is loaded, we can go w/o having to allocate them. We use
pci_cfg_save/restore to restore the BARs with these resources.
This seems to fix the problems that we were seeing that I thought
might have magically gone away in the last revision of cardbus.c (but
really didn't).

shared-last-sector problem.
After this change, even if there is more than one provider with the same
last sector, the proper one will be chosen based on its size.
It still doesn't fix the 'c' partition problem (when da0s1 can be confused
with da0s1c) and situation when 'a' partition starts at offset 0
(then da0s1a can be confused with da0s1 and da0s1c). One can use '-h'
option there, when creating device or avoid sharing last sector.
Actually, when providers share the same last sector and their size is equal,
they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c)
isn't important at all.
- Provide backward compatibility.
- Update copyright's year.

- Add debug.watchdog tunable, so we can specify watchdog CPU from loader
which will help to debug hangs on boot.
- Remove 'U' from debug.watchdog sysctl definition, so if we set it to '-1'
it really shows '-1'.
- Fix comment.
