Make it work, but change the interface to be safe for non-root users. In
particular, right now interface only works for the tables which can be
minimally parsed by kernel to determine the table size. Then, userspace can
query the table size, after that it provides a buffer of needed size
and kernel copies out just table to userspace.
Main advantage is that user no longer need to be able to read /dev/mem,
the disadvantage is the need to have minimal parsers aware of the table
types. Right now the parsers are implemented for ESRT and PROP tables.
Future extension of the present interface might be a return of only
the table physical address, in case kernel does not have suitable
parser yet. Then, a privileged user could read the table from /dev/mem.
This extension, which logically equivalent to the old (non-worked)
EFIIOC_GET_TABLE variant, is not implemented until needed.

Instead of having multiple kyua libraries, just include the files as part
of usr.bin/kyua. Previously, we would build each kyua source up to four
times: once as a .o file and once as a .pieo. Additionally, the kyua
libraries might be built again for compat32. As all the kyua libraries
amount to 102 C++ sources the build time is significant (especially when
using an assertions enabled compiler). This change ensures that we build
306 fewer .cpp source files as part of buildworld.

Building and installing architecture-specific man pages only raises a number of
problems:
* The https://www.freebsd.org/cgi/man.cgi is incomplete. As an
example, it does not show results for pae(4). The reason for this is
that the cgi interface runs on FreeBSD amd64.
* In FreeBSD amd64 some manual pages have broken X-refs. See hptrr(4)
for an example.
* Also, we have broken links in our Release Notes. This is a
consequence of the first point. See
https://www.freebsd.org/releases/13.0R/hardware/#proc-i386.
Make MAN_ARCH default to 'all' so we build all the man pages for all the
architectures. The difference in disk space is negligible. Also link
architecture-specific man pages to their own section while keeping their own
namespace.

In the 2BSD line, the 2.8BSD tapes were the first ones to include a
kernel, both source and a bootable tape. This was an AT&T V7 kernel,
with a number of bug fixes; new features in use at Berkeley; performance
enhancements that were circulating to V7 in the licensee community; and
build system changes. Based on the TUHS archives, it contains none of
the V32 changes, however.
In addition to the source code analysis, Mike Karels relates the story
of how his group lost a customizes to V6 on a PDP-11/40 due to a disk
crash. Since V7 just came out and Bill Jolitz had just brought that up
elsewhere, they replaced their customized V6 with a V7 system, and that
base would eventually become 2.8BSD. (Quarter Century of Unix)
Given both lines of evidence, add a direct line from V7 Unix to 2.8BSD.
Also confirmed that the V6 line to 1BSD and 2BSD was appropriate. 1BSD
and 2BSD included ashell(1) and ex(1). ashell(1) was derived from v6
hell. ex(1) was an enhanced v6 ed. 2.8BSD included process control and
user-land utilities from 4.1BSD

ENETC it a gigabit Ethernet controller found on the LS1028A board.
It supports basic VLAN offloads - tag extraction, injection and hardware
filtering. Inband MDIO connectivity is used for link status
monitoring through the miibus interface. Fixed-link mode is also
supported, which allows for operation of internal cpu to switch port.
Since no admin interrupts are present in hardware, link status polling
has to be used.
Due to a hardware bug software reset of the NIC results in a external
abort. Because of that most of the hardware initialization is done
during attach. This also means that in the case of an fatal error full
board reset is required.
The enetc_hw.h header was imporoted from Linux. It is dual licensed.

Now that the upper layers all go through a layer to tie into these
information functions that translates an sbuf into char * and len. The
current interface suffers issues of what to do in cases of truncation,
etc. Instead, migrate all these functions to using struct sbuf and these
issues go away. The caller is also in charge of any memory allocation
and/or expansion that's needed during this process.
Create a bus_generic_child_{pnpinfo,location} and make it default. It
just returns success. This is for those busses that have no information
for these items. Migrate the now-empty routines to using this as
appropriate.
Document these new interfaces with man pages, and oversight from before.

This is usually an error caused by using an absolute path in SRCS. This
happened to me in 83c20b8a2d due to changing LDADD to SRCS.
I did not notice that this had created a .o file inside the source tree
since .gitignore contains "*.o" and therefore git did not report any
changes.
Adding this warning message to bsd.lib.mk/bsd.prog.mk should prevent
issues like this in the future.
