kernel: Remove ndis(4) and associated tools and stuff.

ndis(4) was a wrapper to allow running binary Windows network
drivers that conformed to the Network Driver Interface Specification,
i.e. NDIS.

It only ever supported drivers from the days of Windows XP and
Windows Server 2003 (i.e. NDIS 5.1). And even if one was actually
able to extract the .sys and .inf files from the driver package and
successfully convert them to a building module, which both were
adventures in itself, it could be any result when trying to run it,
depending on the card and driver, from resonably working to not
working, even crashing. But it did work for some cards, so it had
some limited merit in its time.

NetBSD removed it in 2018, FreeBSD in January 2021, so let's follow
suit now.

Having it as security/pam_ssh solves several issues when using multiple

As I wrote in UPGRADING, the main change for "normal" users is probably
that /var/log/wtmp is no longer logged to, just /var/log/wtmpx.

Leave the old API in libc as compat symbols that do nothing and always
succeed for the run-time linker (i.e. old binaries still using them).

dports has been kindly adjusted by zrj and new binary packages for master
are on their way.

A future commit will provide a wtmpcvt(1) utility to convert old wtmp
files to the wtmpx format.

kernel: Remove puffs(4), putter(9) and associated libs and utilities.

All of these were originally pushed and hooked into the build in non-
working condition so that they would not go stale break building. The
hope was that someone would pick up the work and fix the remaining
issues, which never materialized.

This has led to more harm than good, with people occasionally assuming
that this code is functional. Also, the existence of /usr/include/fuse.h
might lead configure checks into believing that we have a working
implementation.

initrd: Detach from the world and build on the fly

Why
---
Currently, the files for initrd image creation are built and installed at
/usr/share/initrd by "buildworld" and "installworld", respectively, and then
mkinitrd(8) simply packs them to create the initrd.img.gz.

For normal users, the shipped /usr/share/initrd and mkinitrd(8) don't make
much sense, since they don't need to modify the initrd contents and create
a modified initrd image.

From a developer's perspective, the required steps (buildworld, installworld
and mkinitrd) to create and test a new initrd image can be annoying.

How
---
Detach the build and installation of the initrd contents from the world.
Build the (rescue/initrd) tools on-the-fly when creating the initrd image.

As per ftigeot's suggestion, these statically linked tools can be useful when
dealing with a broken system, so install them under /rescue to be more
intuitive and easier to use (similar to FreeBSD and maybe other BSDs).

What
----
* Move "share/initrd" to be top-level, and detach it from world.

+ Update the patch in bsd.crunchgen.mk accordingly.
+ Add Makefile.inc to simplify subdir's makefiles.
+ Rewrite the Makefile with targets:
- rescue: build and install the rescue tools into /rescue.
- initrd: further packs the etc and rescue staffs to create the initrd
image.

* Move "sbin/mkinitrd/mkinitrd.sh" under the new "initrd" directory and adapt
it to work with the "initrd" make target. Remove the other parts of
mkinitrd(8).

* Export the above "rescue" and "initrd" targets to be top-level.

* Update nrelease framework to use the new "make initrd".

* Update build.7 man page accordingly.

* Print the message about updating the initrd image and 3rd-party packages
after "make upgrade" instead of "make installworld".

* Document this change in UPDATING.

* Other small updates and style cleanups.

TODO
----
* Add initrd.7 man page
* Crunch more useful tools
* Crunch bin/sbin/etc. into a bundle to save space (??)

It was unmaintained ever since we inherited it from FreeBSD 4.8.

FAST_IPSEC is the implementation to which FreeBSD has moved since, but
it didn't even build in DragonFly.

bootstrap: Remove helpers for upgrading directly from pre 4.4

This is partly needed to smooth out transition between c++98 to c++14
without switching to a rapid release cycling.

Many changes went in since 4.0 involving btools:
gnu/usr.bin/cc50/cc_tools - iconv() c++ issue, pre 4.4
gnu/usr.bin/grep - max_align_t issue, pre 4.2
usr.bin/chflags - chflagsat(2), pre 4.2
usr.bin/gencat - locales, pre 3.6(4.1 for safety)
usr.bin/sort - isnan(), pre 4.4

It is highly recomended to take an intermediate update step to any of
4.4, 4.6, 4.8 or 5.0 releases first when upgrading from older releases.
