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.

Remove the need for -Wno-pointer-sign. Does not change the output .o file.

Wrap compiler-specific flags with HAVE_GCC and HAVE_PCC as necessary. Add a few flags for PCC.

Add test for HAVE_PCC with HAVE_GCC which turn off compiler warning flags.

branches: 1.33.20;
sprinkle some -fno-strict-aliasing and -Wno-pointer-sign with GCC4.

Add MK... variables to enable/disable various aspects of building
crypto support into the system. See share/mk/bsd.README for more
a full description.

branches: 1.31.2;
libcrypt can now always decrypt, so always -DDES, and eliminate the
<bsd.crypto.mk> song-and-dance.

branches: 1.30.6;
optionally include CRYPTOPATH Makefile.frag files.

Use bsd.crypto.mk.

CFLAGS->CPPFLAGS

kill extra space

Remove WARNS=1 from all the subdirectory Makefiles, and add it to Makefile.inc
now that all /bin has been cleaned.

Avoid the last warnings and add WARNS=1

convert to new RCS id conventions.

Renamed insque

the insque and remque in libcompat don't seem to work (!)

insque is in libcompat

`s3' applies the last substitution to the 3rd (or nth) match.
Split up the code to several files.

Added a line-addressing test so this isn't overlooked again.
Added BACKWARDS directive to Makefile for compatibility.
Completely changed the name space as per FSF's request.
Fixed a line-addressing bug introduced by previous `fix', i.e.,
space preceding a digit acts a plus (+) operator, as in `1 1' == `2',
and a plus operator by itself acts as +1, but a space by itself
should not equal a plus operator, i.e., `1 ' != `1+' == `2'.

Use new POSIX.2 compatible regex routines in C library instead of -lgnuregex.

don't hard-link to 'red' -- that's not a standard BSD thang. If people
want it, they can make the link themselves.

always include libcrypt

Repeating a search requires only `/' (or `?'), not `//' (or `??')
But `s/' is still invalid, use `s//' instead.
If first regex is invalid, regex pointer is now set to NULL so that repeating
the search correctly reports "No previous pattern".

Add RCS identifiers, remove some completely useless RCS logs and patchkit
headers, and a few other insignificant changes.

incorporate changes from 0-9-base to 0-9-ALPHA

branches: 1.12.2;
fixed undo within a global command (would corrupt the buffer)

fixed regex initialization
added more support for BACKWARDS option

Added a restricted mode in the form of a new command: red

added support for lines of arbitrary length
added support for 8-bit data, including NULs

Use global value of CFLAGS for optimization.

rearranged headers to compile cleanly
minor corrections in man page

added man page (draft)
fixed `!' command
final code cleanup

Removed getrange() hack from undo()

added an efficient and relatively clean move (`m' command)
added ustack checking

implemented line marks as pointers
marks to lines that are moved, deleted or otherwise changed are cleared
undo restores cleared marks
added strerror diagnostics

updated to alm's ed-0.2
