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.

In C (not C++), 'naked' inline is almost always a mistake. Either use

My change to allow bootstrapping pwd_mkdb (r363992) resulted in i386 build
failures because the bootstrap header was being included in non-bootstrap chpass.
Dropping the no longer required pwd_mkdb include path from chpass fixes
the build, but to be certain that the failure doesn't get re-introduced,
I've also moved the bootstrap pwd.h into a subdirectory so that adding
-I${SRCTOP}/usr.sbin/pwd_mkdb doesn't pull it in.

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.

While at it add some more comments explaining the current
radix_tree_insert() function and make sure to clean the root node when
the radix tree reaches the maximum height. This can happen if the
index passed is too big when the tree is empty.
The radix_tree_store() function is basically a copy of the
radix_tree_insert() function with some added functionality.
The radix_tree_store() function is local to FreeBSD and does not yet
exist in Linux.

This breaks the build on macOS where this header doesn't exist. I could
also add a compat header to tools/build/cross-build but since it's not
needed removing it seems like the better solution.
Make sure to reclaim epoch structures when they are freed to support
dynamic allocation and freeing of epoch structures.
While at it, move the 64 supported epoch control structures to the
static memory domain. This overall simplifies the management and
debugging of system epoch's.
