Typically <foo>list is used for a structure that holds a list head in
FreeBSD, not for members of a list. As such, rename 'struct aiocblist'
to 'struct kaiocb' (the kernel version of 'struct aiocb').
While here, use more consistent variable names for AIO control blocks:
- Use 'job' instead of 'aiocbe', 'cb', 'cbe', or 'iocb' for kernel job
objects.
- Use 'jobn' instead of 'cbn' for use with TAILQ_FOREACH_SAFE().
- Use 'sjob' and 'sjobn' instead of 'scb' and 'scbn' for fsync jobs.
- Use 'ujob' instead of 'aiocbp', 'job', 'uaiocb', or 'uuaiocb' to hold
a user pointer to a 'struct aiocb'.
- Use 'ujobp' instead of 'aiocbp' for a user pointer to a 'struct aiocb *'.

Major changes:
- Add i219/i219(2) hardware support. (Found on Skylake generation and newer
chipsets.)
- Further to the last Skylake support diff, this one also includes support for
the Lewisburg chipset (i219(3)).
- Add a workaround to an igb hardware errata.
All 1G server products need to have IPv6 extension header parsing turned off.
This should be listed in the specification updates for current 1G server
products, e.g. for i350 it's errata #37 in this document:
http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ethernet-controller-i350-spec-update.pdf
- Avoton (i354) PHY errata workaround added
And a bunch of minor fixes, as well as #defines for things that the current
em(4)/igb(4) drivers don't implement.

Fix EFI boot support when presented with multiple valid boot partitions
across multiple devices.
It now prefers to boot from partitions that are present on the underlying
device that the boot1 image was loaded from. This means that it will boot
from the partitions on device the user chose from EFI boot menu in
preference to those on other devices.
Also fixed is the recovery from a failed attempt to boot, from a seemingly
valid partition, by continuing to trying all other available partitions
no matter what the error.
boot1 now use * to signify a partition what was accepted from the preferred
device and + otherwise.
Finally some error messages where improved and DPRINTF's with slowed boot
to aid debugging.
ZFS will still be preferred over UFS when both are available on the boot
device.

- For non-TSO offloading, we don't need to access mbuf to know
which csum offloading is requested, we can just use the
CSUM_{IP,TCP,UDP} in the csum_flags.
- For TSO offloading, we still can depend on CSUM_{TSO4,TSO6}
in the csum_flags to tell whether the TSO packet is an IPv4
TSO packet or an IPv6 TSO packet.
This streamlines csum offloading handling (remove the two goto)
and allows us the nuke the unnecessary get_transport_proto_type().

with interpreter name exactly matching one wanted by the binary. If
no such brand exists, return first brand which accepted the binary by
note.
The change fixes a regression after r292749, where e.g. our two ia32
compat brands, ia32_brand_info and ia32_brand_oinfo, only differ by
the interpeter path and binary matches to a brand by linkage order.
Then old binaries which require /usr/libexec/ld-elf.so.1 but matched
against ia32_brand_info with interp_path /libexec/ld-elf.so.1, were
considered requiring non-standard interpreter name, and magic to force
ld-elf32.so.1 did not happen.
Note that it might make sense to apply the same selection of brands
for other matching criteria, SCO EI_OSABI and 3.x string.

(1) These functions may be called in interrupt context and pcb_onfault

and restored afterwards.
(2) The check that an abort came either from nested interrupt or while

this case.
These functions are called only for profiling reason, so there will be
