Set WARNS if not set for EFI boot code and fix the issues highlighted by
setting it.
Most components are set to WARNS level 6 with few being left at lower
levels due to the amount of changes needed to fix at higher levels.
Error types fixed:
* Missing / invalid casts
* Missing inner structs
* Unused vars
* Missing static for internal only funcs
* Missing prototypes
* Alignment changes
* Use of uninitialised vars
* Unknown pragma (intrinsic)
* Missing types etc due to missing includes
* printf formatting types

This one mainly avoids mbuf cluster allocation for TCP ACKs during
TCP sending tests. And it gives me ~200Mbps improvement (4.7Gbps
-> 4.9Gbps), when running iperf3 TCP sending test w/ 16 connections.
While I'm here, nuke the unnecessary zeroing out pkthdr.csum_flags.

- Implement the LRO using tcp_lro APIs, and LRO is enabled by default.
- Add several stats sysctl nodes.
- Check IP/TCP length before sending the packet to tcp_lro_rx(), if host
does not provide RX csum information (*); and add an option through
sysctl to always trust host TCP segment csum checks (default is off).
- Add sysctl to control the LRO entry depth; it is disabled by default.
It is used to avoid holding too much TCP segments in driver. Limiting
the LRO entry depth helps a lot in a one/two streams RX test.
This one 3x the RX performance on my local test (3Gbps -> 10Gbps), and
~2x the RX performance over a directly connected 40Ge network (5Gbps ->
9Gbps).
(*) It seems the host stops supplying csum information, once the network
load is high. This still needs investigation...

After r292066, vdev_geom verifies both the vdev and pool guids of device
labels during open. However, spare and l2arc devices don't have pool guids,
so opening them by guid will fail (opening by path, when the pathname is
known, still succeeds). This change allows a vdev to be opened by guid if
the label contains no pool_guid, which is the case for inactive spares and
l2arc devices.

In the event that the getconfig(3) call in svcunix_create is partly successful,
some of the netconfig(3) resources allocated might be leaked if the call returns
NULL as endnetconfig(3) wasn't called explicitly in that case. Ensure that the
resources are fully cleaned up by going to the `done` label, which will call
endnetconfig(3) for us.

by busdma to the blkfront driver must be an integer number of sectors,
and must be aligned in memory on a "sector" boundary.
Having these assertions yesterday would have made finding the bug fixed
in r293698 somewhat easier.
"The problem with the approach taken both in _bus_dmamap_load_pages and
bus_dmamap_load_ma_triv is that they split the request buffer into
arbitrary chunks based on page boundaries, creating segments that no
longer have a size that's a multiple of the sector size. This breaks
drivers like blkfront (and probably other stuff)." [1]
This was most easily triggered by running `fsck /` on a system running
in Xen (e.g. Amazon EC2) but also showed up via growfs(8) and probably
many other userland tools which access the disk directly.

MSDN says that SMB_SET_FILE_END_OF_FILE_INFO uses signed 64-bit integer
to specify offset, but since smbfs_smb_setfsize() has used plain int,
a value was truncated in case when offset was larger than 2G.

In particular, now `truncate -s 10G` will work correctly on the mounted

If available, record the physical path of a vdev in ZFS meta-data.
Do this both when opening the vdev, and when receiving an attribute
change notification from GEOM.
Make vdev_geom_close() synchronous instead of deferring its work to
a GEOM event handler. There is no benefit to deferring the work and
this prevents a future open call from referencing a consumer that is
scheduled for destruction. The close followed by an immediate open
will occur during a vdev reprobe triggered by any type of I/O error.
Consolidate vdev_geom_close() and vdev_geom_detach() into
vdev_geom_close() and vdev_geom_close_locked(). This also moves the
cross linking operations between vdev and GEOM consumer into a
single place (linking in vdev_geom_attach() and unlinking in
vdev_geom_close_locked()).

at line 484. however, this ioctl writes 32 bits of data (u_int *) and
therefore this ioctl will overwrite and corrupt 16 bits of memory.

in6_selectsrc() has 2 class of users: socket-based one (raw/udp/pcb/etc) and
socket-less (ND code). The main reason for that change is inability to
specify non-default FIB for callers w/o socket since (internally) inpcb
is used to determine fib.
As as result, add 2 wrappers for in6_selectsrc() (making in6_selectsrc()
static):
1) in6_selectsrc_socket() for the former class. Embed scope_ambiguous check
along with returning hop limit when needed.
2) in6_selectsrc_addr() for the latter case. Add 'fibnum' argument and
pass IPv6 address w/ explicitly specified scope as separate argument.
