testing/heirloom-mailx: new aport

heirloom-mailx is a clone of System V "mailx", based on Berkeley Mail 8.1.

It has been enhanced to provide all the command line options
required by POSIX, as well as several other features:
* support for MIME, S/MIME, and attachments
* support for SMTP(S), POP3(S), and IMAP(S)
* support for maildir-format email archives
... and much  more.

This is updated from CVS to get current OpenSSL compat.
NSS could be used instead of OpenSSL.
Some security fixes from Florian Weimer are included - see
 http://seclists.org/oss-sec/2014/q4/1066

krb5 is used for IMAP authentication over GSS; our libgss doesn't work
(and might not be OK to link with openssl?) and using libgssglue
will probably require some patching of the makefile.

++[12.5] as of 7/5/10
++* The undocumented contenttype-cntrl option works again (patch by
++  Laurent Parenteau).
++
++[12.5] as of 6/20/10
++* Fixed a message corruption that occurred when the "inc" command was used
++  with a mbox format mailbox after encrypted messages had been viewed
++  (reported by Martin Neitzel).
++* Fixed a condition that caused mailx to hang when looking at a message,
++  copying that message, and issuing a "z" command evaluating an uncached
++  portion of an IMAP folder.
++* Make it compile with OpenSSL 1.0.0-beta2 (patch by Bernhard Rosenkränzer).
++* When executing an "account" command, ensure that the values of the "hold",
++  "keepsave", "append", and "emptybox" variables remain those of the previous
++  account for all outstanding operations on that account (bug reported by
++  Jeff Woodall).
++* Support Gmail IMAP semantics of "delete" turning into "archive". Previously,
++  when mailx was setting the "\Deleted" flag on a message, it did not set any
++  other flags. This caused mails that had been read and then deleted to appear
++  as unread in Gmail's "All Mail". Now, flags besides "\Deleted" are also set,
++  so that they are kept in the archived copy (reported by Jeremy O'Brien).
++* For RFC 2047 MIME "encoded-word" parts in headers, assume that the end of
++  each word resets the conversion state (Yedidyah Bar-David).
++* When the ORGANIZATION variable has an empty value, do not generate an
++  "Organization:" header field. Previously, this condition resulted in
++  mailx refusing to send mail (Thomas E. Kammeyer).
++* When classifying messages with the junk filter, when selecting the most
++  representative tokens, prefer non-junk tokens over junk tokens if both
++  have the same (reversed) probability, in order to avoid false positives.
++* When calculating the probabilities of tokens that have occurred only in
++  good messages or only in junk messages so far, and these tokens occurred
++  less than ten times, give them slightly less than the minimum/maximum.
++* Fixed "unignore" and similar commands; they did not work at all so far
++  (http://www.freebsd.org/cgi/query-pr.cgi?pr=146280).
++
+ [12.4] released 7/29/08
+ * With the "-E" command line option or if the "skipemptybody" variable is
+   set, outgoing messages that contain no text in their first or only part
