Remove $FreeBSD$: two-line nroff pattern

Remove /^\.\\"\n\.\\"\s*\$FreeBSD\$$\n/

Indicate which port gpg.1 comes from.

enigma(1) Remove reference to PGP; modernize a bit

- the port was removed 2017-06-07 in r442847
- gnupg1 is the older version of gpg with legacy PGP support
- remove unused macro
- remove now-false statement about export restrictions

Remove bdes(1)

The use of DES for anything is discouraged, especially with a static IV of 0

If you still need bdes(1) to decrypt Kirk's video lectures, see
security/bdes in ports.

mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

When I wrote this man page more than 5 years ago, I simply didn't
understand the true symmetric nature of Enigma, so my description of
``automatically detects that the input is encrypted'' was simply
wrong. Replace that by a more accurate description of why feeding the
ciphertext again into the engine will decrypt it.

Some man page cleanup. Make the NAME and SYNOPSIS sections agree so
that whatis(1) will produce the expected results.

Typo.

Fix some of the more blatant bugs in the original code, provide a
BSD-able Makefile, add a man page (that also puts a bold warning about
the weakness of the encryption), and implement the -k option for
compatibility with other vendor's implementations. (Unlike those
other vendors, we actually also document this option and its
problems.)

There are more violations of style(9) in it, like the not-use of
getopt(3), but it's not worth the while fixing all of this.
