If for some reason building without 'git', you'll need these 2 files to
already exist somehow - still need to work that out (e.g. for daily
built-source archives).

Need to update the Windows build to generate these files now.

This fixes issue #194 reported by mlong.

Always use the return value of term_supports(), which correctly supports pre-logon and auto-terminal-capability-detection, rather than useron.misc for all door drop file generation.

This should resolve the issue recently discussed in #synchronet with regards to a user getting non-ANSI output from door games even when using an ANSI-capable terminal.

When forwarding a single-part MIME-encoded HTML email, the preamble (original message header info) and any user comments, need to be HTML-encoded.

Add the commonly-used "Fwd: " prefix to the default message subject, when forwarding.

This required that smb_getplaintext() no longer always-NULLify the message's text_subtype (e.g. "html"). For single-part messages, this element was getting freed and NULLed.

Add/use a new SMBLIB convenience function to add a string header field, but only if non-NULL: smb_hfield_string()

Add configurable options for email validation (length and valid chars)

See merge request !62

Since we're calling smb_getplaintext() manually here, and its not going to return the comment headers as part of the plain-text (the way smb_getmsgtxt() can), so we need to display find/display the comment headers first.

even when GETMSGTXT_PLAIN mode flag is used and the message contains a MIME-encoded plain-text portion. Obviously the GETMSGTXT_NO_HFIELDS exception still applies.

The fixed problem was when forwarding a MIME-encoded email, the forwarding information (and user comment, if supplied) could be suppressed/lost.

The new messages subject may be passed into forwardmail(). If it isn't, it'll be prompted for (defaulting to the original message subject).

Also, fix forwarding to QWKnet (look-up full-route/to-user-number).

reported by Nelgin.

smb_getmsgtxt() returns any "comment" headers as part of the message body text, and has since 2003.
When I added mail->netmail (stored message) export support to SBBSecho v3, I duplicated this logic, so comment headers were added *twice* to exported netmail messages. Oops. I didn't notice until today when playing with forwarding-to-netmail (FTN).

Also noticed and fixed: any comment headers in posted messages (unlikely/uncommon) would not be exported to EchoMail messages. Use the correct smb_getmsgtxt() mode flags ("NO_TAILS" instead of "BODY_ONLY") - I know, not great names.

User number is not always relevant (e.g. could be #0) when sending
netmail, so don't show that. And the CRLF at in the Forwarded string
appears extraneous.

No longer derive the new message header from the original - too many problems. Simplified the forwarding support smblib (multiple SENDER* and RECIPIENT* header fields no longer expected/supported). Technically, the FORWARDED header field really serves no important purpose now.
A comment can be passed into forwardmail() or (if NULL), will be prompted for. There is an issue where the added comment can be obscured by the receiving mail program if the original message is a multi-part MIME message. Not sure the best solution for that. Still a WIP in that regard.

Update comments on jsonclient

Only do the local user notification when appropriate.
Signal the FTN netmail semaphore when appropriate.

Fix bug that corrupts the menu after deleting menus

Closes #83, #108, #141.
Still to do: expose via JS (e.g. for use in msglist.js).

Copy some code from atcodes.cpp to show all the aux and network attributes.

Also, the MsgAttr text.dat string only contains 17 %s's but we were passing 18, so the last attribute (KillSent) would never be shown.

Instead, split this into 3 strings and just pass those 3 strings to the MsgAttr format string along with a ton of blank strings. So we don't have to keep updating the MsgAttr text.dat string every time we add more attribute flags (that was kind of ridiculous).

Use ctime_r() to dump the forwarded date/time.
Correct some other unsafe uses of ctime() here (replace with cime_r).
Fix the accidental reference to the GPL license (it's actually LGPL for smblib).

The convenience pointers to_ext and to_net need to be invalidated (nullified) if we are going to allow forwarding from local email boxes to network mail and keep all the original message header fields in tact.

The "Forwarded" field must now be added *before* any new recipient information (local user extension or network address of the forwarding destination).

This is part of the solution to request #83, #108, and #141.

New JS User.stats properties:
- read_mail_waiting
- unread_mail_waiting
- spam_waiting

New @-codes:
- MAILR (read mail waiting)
- MAILU (unread mail waiting)

And the corresponding MAILR# and MAILU# codes (for non-current user's stats).

Addresses feature request #191.

Barren Realms Elite 3rd party install config

Just like the exec and eval sections, except executed/evaluated *before*
any external programs are installed.
New optional 'fail' key to specify a custom failure message.
Example:
[pre-eval:file_exists(startup_dir + 'test.txt')]
prompt = false
required = true
fail = You must create text.txt before you can install.

... as pointed out by Nelgin. You can toggle more than one sub-board/directory's "template" option to "Yes". But only the first such sub/dir is actually the template, so only indicate the first such sub with a splat ('*').

There is no actual TCP-client when a timed event is executing, so don't create one in the JS context when the socket is invalid.

Don't display the text.dat SelectItemHdr if an xtrn_sec_head.* file was shown.
Center the sections and the "Which" prompt when the "center=true" modopts.ini
option is set.

Add support for modopts.ini "center=true" option to center single-column
program listing in the terminal.

When a custom section header files (xtrn<sec>_head.*) is displayed, don't
print the XtrnProgLstHdr string from the text.dat.

xp_inet_pton() now sets the socket errno value, doing as instructed by the TODO.

Mr. Millionaire's request.

printfile() assumes you want the file displayed starting in column 0, so will send a CRLF to insure that it does (unless the P_NOCRLF mode flag is specified). But this CRLF printing was happening before the file was opened and when the P_NOERROR mode flag is specified, this should be a silent failure with no print output. So move the CRLF printing to *after* the file is opened.

This expose an issue in the latest xtrn_sec.js where it makes several calls to bbs.menu() with the P_NOERROR mode flag set, expecting nothing to happen if/when the optional display files (e.g. xtrn*_tail.*) don't exist.

Reported by JC via IRC.

When system.new_user() was called but the current "client" object is uninitialized (e.g. has NULL protocol, host or IP address fields because there is no active client, e.g. because is was called from a timed event with active user online) - this code would dereference a NULL pointer and crash the b0rad. Reported by Mortifis.
