If the TLS context couldn't be created, don't listen on the TLS interfaces.

the are likely to only impact the current connection, not overall system
operation.

TLS (HTTPS) will not be enabled/supported in the web server.
Lowered the log level of the cryptlib failures in handle_crypt_call() from
LOG_ERR to LOG_WARNING since these apparently are expected failures when
interacting with misbehaving HTTPS/TLS clients.

toggle option after being changed from the File Scan Configuration menu.

set the "extended description" flag for all subsequently added files if one of
the files uploaded/added contained an embedded description (FILE_ID.DIZ)
causing garbage extended description display when viewing extended information
on files that did not in fact have an embedded description.

- Display the user's last IP address (no longer stored in the "Note" field)
- Moved the deleted/inactive user indicator to the last line before the prompt
- Requires new text.dat entry: UserIpAddr (line 768).
Other text.dat changes:
- Changed the EnterYourComputer prompt to be more accurate
- NewUserFeedbackHdr and UeditAddressBirthday say "BDay" instead of "BD"
- Display Client and Protocol instead of Computer and Connection in uedit.
- UeditPrompt no longer has the leading CRLF embedded in it.

- Display the user's last IP address (no longer stored in the "Note" field)
- Moved the deleted/inactive user indicator to the last line before the prompt
- Requires new text.dat entry: UserIpAddr (line 768).

Writing modem/protocol value to new "IP Address" field in user record.

seperators) and return a 400 error otherwise.  With this check before the
vhost is set, eliminates the need to check when setting the log file name.

Also, lower-case hostnames for consistency and simpler validity checking.

but contains a full struct sockaddr.  We no longer need a separate field for
the address family.

Also, when populating the addr member, simply memcpy() the whole addr, not
the binary address part (derp).

failed login attempt client IP addresses on Windows.

bcc32 pads differently than msvc when an odd-sized string is inserted in
the middle of a structure, so chagne the addr[] field to a nice "power of 2"
size: 128. This allows sbbsctrl.exe client window to work again.
Use uint16_t instead of WORD for the TCP port element, just because.

since that is the only file we're reading in this function.
For some unkonwn reason, opening mail.sdt can sometimes take as long
as 2-3 seconds when the file is on a SMB/CIFS share. This could cause calls to
getmail() to stall noticeably (e.g. sbbsctrl, with the Statistics windows
visible) and logging into the terminal server or viewing user statistics. This
is a new problem, perhaps only with Vertrauen, but this optimization helps
to eliviate the most obvious performance problems triggered by it.
Better/safer string modification (e.g. use of SAFEPRINTF).

filename if it contains any path delimiters.

again for backward compatability (and should no longer be used, but whatever).

obsolete.  If there is no IPv4 address, return "255.255.255.255".

Rename the array to interface_ip_addr_list.

Create a new function to close without one and use it instead until the
ring buffer is created.
