Fix handling of .note.ABI-tag section for GNU systems [1].
Handle GNU/Linux according to LSB Core Specification 4.0,
Chapter 11. Object Format, 11.8. ABI note tag.
Also check the first word of desc, not only name, according to
glibc abi-tags specification to distinguish between Linux and
kFreeBSD.
Add explicit handling for Debian GNU/kFreeBSD, which runs
on our kernels as well [2].
In {amd64,i386}/trap.c, when checking osrel of the current process,
also check the ABI to not change the signal behaviour for Linux
binary processes, now that we save an osrel version for all three
from the lists above in struct proc [2].
These changes make it possible to run FreeBSD, Debian GNU/kFreeBSD
and Linux binaries on the same machine again for at least i386 and
amd64, and no longer break kFreeBSD which was detected as GNU(/Linux).

Tweak the way that the ACPI and ISA bus drivers match hint devices to
BIOS-enumerated devices:
- Assume a device is a match if the memory and I/O ports match even if the
IRQ or DRQ is wrong or missing. Some BIOSes don't include an IRQ for
the atrtc device for example.
- Add a hack to better match floppy controller devices. Many BIOSes do not
include the starting port of the floppy controller listed in the hints
(0x3f0) in the resources for the device. So far, however, all the BIOS
variations encountered do include the 'port + 2' resource (0x3f2), so
adjust the matching for "fdc" devices to look for 'port + 2'.

Fix ipfw's initialization functions to get the correct order of evaluation
to allow vnet and non vnet operation. Move some functions from ip_fw_pfil.c
to ip_fw2.c and mode to mostly using the SYSINIT and VNET_SYSINIT handlers
instead of the modevent handler. Correct some spelling errors in comments
in the affected code. Note this bug fixes a crash in NON VIMAGE kernels when
ipfw is unloaded.
This patch is a minimal patch for 8.0
I have a much larger patch that actually fixes the underlying problems
that will be applied after 8.0

This patch fixes two bugs in sglist(9) and improves robustness of the API via
better semantics if a request to append an address range to an existing list
fails.
- When cloning an sglist, properly set the length in the new sglist instead of
leaving the new list empty.
- Properly compute the amount of data added to an sglist via
_sglist_append_buf(). This allows sglist_consume_uio() to properly update
uio_resid.
- When a request to append an address range to a scatter/gather list fails,
restore the sglist to the state it had at the start of the function call
instead of resetting it to an empty list.

Fix USB cache sync operations for platforms with non-coherent DMA.
- usb_pc_cpu_invalidate() is called between [consecutive] reads from a device,
so a sequence of BUS_DMASYNC_POSTREAD and _PREREAD should be used. Note we
cannot use or'ed shorthand ( _POSTREAD | _PREREAD) for BUS_DMASYNC flags, as
the low level bus dma sync operation is implementation dependent and we
cannot assume the required order of operations to be guaranteed.
- usb_pc_cpu_flush() is called before writing to a device, so
BUS_DMASYNC_PREWRITE should be used.

Backout r193289. r193289 restored page select bits to previous
value instead of blindly resetting it to 0. However, it seems page
select bits of some 88E1116 PHY is initialized to invalid one such
that restoring page select bits after programming broke MII
register access. The correct solution would be reset page select
bits to 0 in PHY attach stage but it would require more testing.
Since we're in BETA stage such a change would be dangerous so just
back it out.
This change should fix nfe(4) breakage on NVIDIA MCP55.

getcwd() (when __getcwd() fails) works by stating current directory, going up

.zfs/ directory this doesn't work, because .zfs/ is hidden by default, so it
won't be visible in readdir output.
Fix this by implementing VPTOCNP for snapshot directories, so __getcwd()
doesn't fail and getcwd() doesn't have to use readdir method.
