Remove MKCRYPTO option.

Originally, MKCRYPTO was introduced because the United States
classified cryptography as a munition and restricted its export. The
export controls were substantially relaxed fifteen years ago, and are
essentially irrelevant for software with published source code.

In the intervening time, nobody bothered to remove the option after
its motivation -- the US export restriction -- was eliminated. I'm
not aware of any other operating system that has a similar option; I
expect it is mainly out of apathy for churn that we still have it.
Today, cryptography is an essential part of modern computing -- you
can't use the internet responsibly without cryptography.

The position of the TNF board of directors is that TNF makes no
representation that MKCRYPTO=no satisfies any country's cryptography
regulations.

My personal position is that the availability of cryptography is a
basic human right; that any local laws restricting it to a privileged
few are fundamentally immoral; and that it is wrong for developers to
spend effort crippling cryptography to work around such laws.

As proposed on tech-crypto, tech-security, and tech-userlevel to no
objections:

https://mail-index.netbsd.org/tech-userlevel/2017/05/06/msg010547.html

P.S. Reviewing all the uses of MKCRYPTO in src revealed a lot of
*bad* crypto that was conditional on it, e.g. DES in telnet... That
should probably be removed too, but on the grounds that it is bad,
not on the grounds that it is (nominally) crypto.

don't install crypto files with MKCRYPTO=no. with these changes, a
MKCRYPTO=no build completes.

Consistently use CONFIGFILES & CONFIGLINKS (which enable the 'configinstall'
target) instead of using home-grown 'distribution' targets or using
FILES with the 'install' target.
Add some etc/ subdir Makefiles where appropriate.

XXX: some of etc/Makefile install-etc-files could be converted to CONFIGFILES.

babylon5 ssh key changed (due to reinstall)

releng has been on mollari for a while now. Also, add wiki

add morden, mollari, pkgbuild and build

Remove key for "tgm.netbsd.org". The machine was put out of service when
the new autobuild cluster was brought up.

- .isc.netbsd.org aliases are gone
- zathras is gone, alias releng to www

branches: 1.2.2;
The previous version of this file had the wrong key for cvs.netbsd.org(!);
it had the key from before the machine was officially placed in service
as "cvs.netbsd.org". Replace with correct key. Duh.

Moved from src/etc. known_hosts file containing Project servers.
