Move ifconfig SFP status functionality into libifconfig
libifconfig_sfp.h provides an API in libifconfig for querying SFP module
properties, operational status, and vendor strings, as well as descriptions
of the various fields, string conversions, and other useful helpers for
implementing user interfaces.
SFP module status is obtained by reading registers via an I2C interface.
Descriptions of these registers and the values therein have been collected
in a Lua table which is used to generate all the boilerplace C headers and
source files for accessing these values, their names, and descriptions.
The generated code is fully commented and readable.
This is the first use of libifconfig in ifconfig itself. For now, the
scope remains very limited. Over time, more of ifconfig will be replaced
with libifconfig.
Some minor changes to the formatting of ifconfig output have been made:
- Module memory hex dumps are indented one extra space as a result of using
hexdump(3) instead of a bespoke hex dump function.
- Media descriptions have an added two-character short-name in parenthesis.
- QSFP modules were incorrectly displaying TX bias current as power. Now
TX channels display bias current, and this change has been made for both
SFP and QSFP modules for consistency.
A Lua binding for libifconfig including this functionality is implemented
but has not been included in this commit. The plan is for it to be
committed after dynamic module loading has been enabled in flua.

The practice of creating symbolic links is somewhat fragile. Always
make copies instead.
There's too many times that we can't run the new binaries with old
libraries. Making the links when things are known to be 'safe' is a
nice optimization, but a copy of all the binaries is only 30MB, so
saving the copies at the cost of increased support when new symbols
are added and used as part of the bootstrap seems to be unwise.
There may be additional optimizations possible here, especially for
!FreeBSD hosts. However, that's beyond the scope of the problem I'm
trying to fix with make failing mid-way through an installworld across
change r363679. This optimization there caused us to run a new binary
with an old library once a new make was installed due to the symbolic
link. One could just copy make, but then other binaries fail as well,
so rather than play whack-a-mole, I opted to take us back to the old
way. Before r340157 or so we did copies (thogh of a lot fewer
artifacts), and we didn't have issues like this.

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.
