pipe: reduce atime precision
The routine is called on successful write and read, which on pipes happens a
lot and for small sizes.
Precision provided by default seems way bigger than necessary and it causes
problems in vms on amd64 (it rdtscp's which vmexits). getnanotime seems to
provide the level roughly in lines of Linux so we should be good here.

Note the that atime handling for named pipes is broken with and without the
patch. The filesystem code is never used for updating atime and never looks
at the updated field. Consequently, while there are no provisions added to
handle named pipes separately, the change is a nop for that case.

MFOpenZFS: Add support for boot environment data to be stored in the label
We are building new bootonce mechanism (previously zfs bootnext) and it is
based on this OpenZFS change. Since this patch is nicely self contained,
I am commiting it as is, and we can stack our changes.
Original patch description follows:
Modern bootloaders leverage data stored in the root filesystem to
enable some of their powerful features. GRUB specifically has a grubenv
file which can store large amounts of configuration data that can be
read and written at boot time and during normal operation. This allows
sysadmins to configure useful features like automated failover after
failed boot attempts. Unfortunately, due to the Copy-on-Write nature
of ZFS, the standard behavior of these tools cannot handle writing to
ZFS files safely at boot time. We need an alternative way to store
data that allows the bootloader to make changes to the data.
This work is very similar to work that was done on Illumos to enable
similar functionality in the FreeBSD bootloader. This patch is different
in that the data being stored is a raw grubenv file; this file can store
arbitrary variables and values, and the scripting provided by grub is
powerful enough that special structures are not required to implement
advanced behavior.
We repurpose the second padding area in each label to store the grubenv
file, protected by an embedded checksum. We add two ioctls to get and
set this data, and libzfs_core and libzfs functions to access them more
easily. There are no direct command line interfaces to these functions;
these will be added directly to the bootloader utilities.

While here reorder struct namecache so that most commonly used fields
are closer.
Upper level protocols defer checksums calculation in hope we have
checksums offloading in a network card. CSUM_DELAY_DATA flag is used
to determine that checksum calculation was deferred. And IP output
routine checks for this flag before pass mbuf to lower layer. Forwarded
packets have not this flag.
NAT64 uses checksums adjustment when it translates IP headers.
In most cases NAT64 is used for forwarded packets, but in case when it
handles locally originated packets we need to finish checksum calculation
that was deferred to correctly adjust it.
Add check for presence of CSUM_DELAY_DATA flag and finish checksum
calculation before adjustment.

1.) #if/#else wasn't taken into account at all for maxsyscall figures, but
2.) We didn't validate contiguous syscall numbers anyways...
This kind of inconsistency is bad as we don't currently ensure explicit
indexing of, e.g., the sysent array if one syscall is unimplemented/missing.
This could be fixed and might be more robust, but it's also good to have the
"documentation" that comes from being explicit as to what the missing
syscalls are.
The new version looks much like the awk version; stash off the current
'last highest syscall seen' if we hit an #if, restore to that if we hit an
#else, and make sure that we're explicitly always defining the next syscall.
The logic at the tail end of process_syscall_def that moves maxsyscall has
been 'cleaned up' a little since we're now ensuring that it's monotonically
increasing earlier in the function. At the moment I think it's unlikely we'd
see range-definitions that are not UNIMPL, but there's no reason to
specifically handle that case for bumping maxsyscall there.
This change was provoked by reading the commit message for r363832 and
realizing that this validation hadn't been included in the initial rewrite
to lua.
