c4ba4aa547 libifconfig: Overhaul ifconfig_media_* interfaces
Define an ifmedia_t type to use for ifmedia words.

Add ifconfig_media_lookup_* functions to lookup ifmedia words by name.

Get media options as an array of option names rather than formatting it
as a comma-delimited list into a buffer.

Sprinkle const on static the static description tables for peace of
mind.

Don't need to zero memory allocated by calloc.

94cba8034b 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.

e5539fb618 libifconfig: Add function to get bridge status
The new function operates similarly to ifconfig_lagg_get_lagg_status and
likewise is accompanied by a function to free the bridge status data structure.

I have included in this patch the relocation of some strings describing STP
parameters and the PV2ID macro from ifconfig into net/if_bridgevar.h as they
are useful for consumers of libifconfig.

b1d757bc1d libifconfig: multiple feature additions
Added the ability to:

* Create virtual interfaces
* Create vlan interfaces
* Get interface fib
* Get interface groups
* Get interface status
* Get nd6 info
* Get media status
* Get additional ifaddr info in a convenient struct
* Get vhids
* Get carp info
* Get lagg and laggport status
* Iterate over all interfaces and ifaddrs

And add more examples, too.

Note that this is a backwards-incompatible change. But that's ok, because it's
a private library.

c2803f1a04 libifconfig: allow to get original interface name via ifconfig_get_orig_name()
Uses the same method as in tools/tools/ifinfo/ifinfo.c
(via net.link.generic sysctl).

Tested with modified wlandebug(8).

ec21434933 Renaming libifc to libifconfig in response to feedback on initial commit of
this library. Sticking to 'libifconfig' (and 'ifconfig_' as function prefix)
should reduce chances of namespace collisions, make it more clear what the
library does, and be more in line with existing libraries.
