... who knew?

And remove the "CHRS: " portion of the FIDO_CHARSET_UTF8 definition as we're
now storing these values in their own SMB hfields (FIDOCHARSET), not FIDOCTRL.

Created struct fidoaddr (5D address), though it's only used (so far)
in pktdump.c - doesn't really need to be packed.

* AreaFix updates:
- No longer accepts AreaFix requests to "SBBSecho", since we send mail from
  that name, accepting mail to the same name can create a bot-loop
- Each linked node has a configurable "name" now, where to send notifications
  (not always "sysop")
- AreaFix support for a node can be toggled without clearing their AreaMgr
  password
- Area listings now include the echo descriptions (when available)
- Fix: the badecho is not included in area lists returned via netmail
- Improved log output around AreaFix requests/operations
- %echostats [echo] command now supported to request most recents stats for
  an area
- Notifications can now be toggled by AreaFix sysops using %NOTIFY On/Off
- Notification mail to the local Area Manager (sysop) now have the correct date
  time/zone in the message header (not copied from the AreaFix request)

* Added support for auto-responding to PING NetMail requests
* When exporting EchoMail, if the date/time written or imported exceeds the
  configured maximum age for EchoMail, don't export it (rescan exempted)
* The -g (generate notification messages) works with a passed address now
* Better grunged packet detection (e.g. NULL-terminated header fields must be
  NULL-terminated)
* Avoid bot-loop by refusing to send netmail from "SBBSecho" to "SBBSecho"
  If you setup an echolist to forward areafix requests to your hub a loop could
  occur :-(

Use more formal terminology (e.g. "Type-2", not "type 2.0").

- When importing echomail packets and tossing to linked-nodes, don't loop
messages back to originating nodes, even if their address is not in the PATH or
SEEN-BYs.
- To get the full originating address of an echomail message (for loop-back
prevention), parse the Origin Line before tossing to links. If the Origin Line
cannot be parsed, log a warning message.

FidoNet NetMail can now be gated to an SMTP client (as before), but replies are
now successfully gated back to FTN NetMail. This uses a new more RFC-compliant
To/From address header field format, so older messages (previously gated to
an SMTP client) cannot be successfully replied-to. Tested with Microsoft
"Windows Live Mail 2012" (previously known as Outlook Express).
Test reports/results with other SMTP mail clients would be welcome.

Requires SBBSecho v2.30 or later. File attachments are not yet supported.

Print wanring if type 2+ orig/dest zones don't match the zone fields in the
type-2 portion of the header.
Updated some pkt header field names in fidodefs.h.

header fields, not just the filler portion) - much more sane.

(these are not fidonet standard values).

anyway, so unnecessary.

Moved fmsghdr_t and attribute constant definitions from sbbsdefs.h.
