was never used. This was intended to be a method for internationalization,
letting the sysop change which key is used as the uiniversal "quit" key.
This commit replaces most of the uses of the hard-coded 'Q' for quit wtih the
3rd charcter in the text.dat YNQP string. Some hard-coded menus still have the
'Q' key hard-coded and will need to be addressed later. The text.h YN index
macro was changed to YNQP and the JS text index variable name will change
as well.

to allow the caller to skip the question (ie: for new user feedback validation)
This replaces the "never prompt for validation user" patch since:

DigitalMan: I suppose if someone has an issue, a new mode bit could be burned for that

Is clearly permission.

to forward to external mail address), don't prompt the user if they wish to
forward (always forward).
More safe string copying/formatting.

all exported functions and data types using a 32-bit time_t (time32_t).

especially through SMTP (where these values are exposed via the Originator-info
header field): SENDERUSERID, SENDERSERVER, and SERVERTIME.

unlimited number of emails per day.

That is, if any of the following text.dat entries are set to a blank/emtpy
string (by editing ctrl/text.dat or via run-time script modification), the
question will not be asked of the user allowing greater sysop-customization
of hard-coded processes (e.g. new user application):

inserting (long) typedefs to prevent warnings, but in the case of the JS File()
class, actually supporting file lengths > 32-bit.

Added FTN PID header field to all messages created by sbbs.

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).

name.

Added HOST and IP keywords to allow restricted access/privileges to/for
specific remote hostnames or IP addresses (wildcards allowed).
All string-argument type ARS keywords (e.g. SHELL, PROT, etc.) now support .can
style wildcards.
The current remote client is now used for protocol, host, and IP ARS checking,
when available, so this requires passing the client pointer around (which
explains why so many files are touched by this change) and takes care of a
long standing to-do item (the user's 'modem' value was used for the PROT
value checking, which was not always correct).

by properly const-ifying the appropriate functions and variables.

single function.
* editfile() now modifies a temporary copy of the file which solves 2 problems:
A. editors restricted to the temp dir (e.g. PICO) can now be used to edit other
    files (e.g. sig files)
B. DOS editors can now be used to edit files with long filenames
    (e.g. .plan files)

Uploads in E-mail is set to "No". This option has been in SCFG for 10(+?) years
and was never used. :-)

no need to do manual initialization here.

Created DLL-exported msg_client_hfields() in postmsg.cpp as a common function
to add these client tracking header fields.

smb_read() will now retry the read operation if the read fails with an errno of
DEADLOCK (occurs on Unix if a Win32 system has the bytes already locked).

the system timezone, which handles the optional automatic toggle of the DST bit
for US-zones in real-time. Previously, the DST flag would only be toggled when
loading configuration files, now it will happen in real-time.

smb_hfield_append_str() used for creating and appending ASCIIZ header fields.
These functions handle the string-length calculation automatically.
