This is intended to (eventually) be a translation of the current Usurper
Pascal code into C with the only major change being the use of memory mapped
files for IPC and game data.

This model should help greatly with the most common Usurper issues, but it
adds the constraint that all nodes must be running on the same system.

Initially, game play is intended to be identical, and new bugs will be
introduced from the C translation.  As such, this is not intended as a
replacement for Usurper in the near future except the code is being written
for *nix systems initially and will be ported to Win32 at a later time.

"Normally, this response will be a multiline reply. Each line of the
response contains a keyword and, optionally, one or more parameters."
Added RFC1870 Message Size Declaration support to EHLO response.
Strip optional parameters from MAIL FROM command (per RFC1869).

Removed cruft from output files.

output of nodestatus() (e.g. used by Synchronet Control Panel node window).

directing the log output accordingly (apparently online is not always being set
to ON_LOCAL as expected, checking node_num is more a consistent method).

some other single-line messages (replacing static strings).

Don't prompt for "delete mail from everyone" when there is only one e-mail
waiting for the user.
Use some existing text.dat entries (some old and some recently added) where
identical static strings were still being used for no apparent reason.
Added several text.dat entries for the QWK settings menu, node status, and
some other single-line messages (replacing static strings).

be replied to (e.g. with a bounce message) - used by the list server.

recipients (don't assume NET_INTERNET).

bulkmail.js, except the text may contain personalized text (e.g. the user's
password) for each recipient.

Type mismatch in parameter 'optlen' (wanted 'int *', got 'unsigned int') in function nonblocking_connect

comparing in matchuser() - so "digit alman" matches "digital man", etc.

Get the last socket error instead and return that (not tested on Win32)

  DreamForge-based servers (Unreal, et al), which do not support the state
  message.

SENDER field with trailing whitespace removed.
Added hash file validation (checks message numbers, times, source type values).

Ragnarok - sub_list would be populated for sub-boards current user did not have
access to (grp_list element did not exist, but subs could still be accessed via
msg_area.grp) and can_read property did not check group access.
Created userdat convenience functions for checking access/read/op rights to
sub-boards.

the status bar directly (this is now handled in the UpTimerTick), thus
preventing crashes if 2 callbacks are called concurrently.

* double spam.log entry ("TAGGED" and "IGNORED") for the same message
* DNSBL_IGNORE option did not work unless the DNSBL_SPAMHASH was enabled
