attached to a parent interface we use its mutex to lock the softc. This
means that in several places like carp_ioctl() we lock softc conditionaly.
This should be redesigned.
To avoid LORs when MII announces us a link state change, we schedule
a quick callout and call carp_carpdev_state_locked() from it.
Initialize callouts using NET_CALLOUT_MPSAFE.

o usb_subr.c, add delta 1.119:
Move usb_get_string() and make it public.
o usbdi.c, bring on par with 1.106, this includes:
- Make an iterator abstraction for looping through all descriptors.
- Whine about not being able to figure out default language if we are debugging.
- Move usb_get_string() and make it public.
o usbdi.h, bring on par with 1.64, this includes:
- Make an iterator abstraction for looping through all descriptors.
- Move usb_get_string() and make it public.
o usbdi_util.c, bring on par with 1.42, this includes:
- Add usbd_get_protocol().
- Use NULL instead of 0.
- Fix (mostly harmless) typo.

is particularly useful when VESA is available (either `options VESA'
or load the vesa module), as BIOSes in some notebooks may correctly
save and restore LCD panel settings using VESA in cases where calling
the video BIOS POST is not effective. On some systems it may also
be necessary to set the hw.acpi.reset_video sysctl to 0.
Also save the DAC state, increase the maximum save state size from
4k to 8k, and refuse to save the VESA state if the BIOS reports it
is larger than the maximum size we can handle.
It doesn't appear that anything currently uses this code, but it
turns out to be capable of restoring some notebook displays to a
working state after a suspend-resume cycle.
if either INVARIANTS or INVARIANT_SUPPORT is defined so that kernel modules
that want to use mtx_assert() only need to define INVARIANTS.

- 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.
