The previous default of "balanced" appears to have caused pathological
behavior, including very poor performance and 100% CPU load in the
arc_reclaim_thread.
The symptoms appeared when the daily periodic run started.
With this change, the system--and the ARC in particular--behaved
normally during a manual daily periodic run.
From Mark Johnston: The port of the balanced strategy is incomplete,
since arc_prune_async() is a no-op on FreeBSD. (This also seems
to imply that r337653 is a no-op.) After 12 is branched we can
port the remaining bits and consider changing the default back.

Reflect the fact that ig4(4) is not an Intel-specific device but
a driver for Synopsys DesignWare I2C controller that now ships in
AMD systems too.

notices the missing ntpd user and refers to UPDATING. This change makes
it more clear which aspect of UPDATING is important for the ntpd change.

Output padding is specified via outlen, which is set using the return value
of fprintf. Because it's printing that padding plus a trailing byte, it
grows by one each iteration rather than reflecting actual length.
Additionally, iec was sized improperly for scaling up similarly to si.
Fixing this revealed that the humanize_number(3) call to populate persec
was using the wrong width.

r338642 toggled the REPRODUCIBLE_BUILD knob but missed the
corresponding kern.opts.mk change.
We want to build the 12.0 release artifacts with reproducible builds
mode enabled. Switch it on in HEAD now to enable testing with upcoming
ALPHA builds. We can revisit the default setting for HEAD after the
branch is created.
This change eliminates the build metadata (user, hostname, timestamp,
etc.) from the kernel and loader. If the src tree is a git, svn or p4
checkout with changes then the metadata is retained.
The WITHOUT_REPRODUCIBLE_BUILD src.conf(5) knob can be used to revert
to the previous behaviour.

Both drivers use this interface so add a dependancy on it.
Since awg uses aw_sid for generating the MAC address, make it
depend on both aw_sid and nmvem so when only removing nvmem from
kernel config it will not include this driver.
