... using uncrustify mod_paren_on_return config

White-space changes only, exception being the rare insertion of NL before
closing brace (couldn't find the option to disable that behavior).

I excluded some header files (e.g. sbbs.h) since uncrustify seemed to be doing
more harm than good there. I might just end up applying different set of rules
to .h files.

like datestr() does.

datestr() will return this string when passed a time_t value of 0.

Vertrauen's FTP server gets abused by QWKnet logins sometimes and handling
the race conditions around QWK packet creation attempts is silly - there's
no legit reason why a QWKnet account needs to be logged-in multiple times
concurrently to the hub's FTP server, so reject the subsequent logins even
when they're on different hosts (as is the case with Vertrauen).

As part of this change:
- fmutex() now takes an new time_t* argument to (optionally) store the
  time of the mutex file for helping logging (locked since when?).
- time_as_hhmm() created to format a string as either HH:MM or HH:MM[a|p]
  (depending on system configuration for 12 or 24 hour time formatting).
- renamed the old hhmmtostr ()to tm_as_hhmm() (since it takes a struct tm arg)
  and have it return a non-padded string (useful in more situations without
  requiring truncation) when the sysop prefers 24-hour time.

For cases where we want to the verbal short date output, regardless of sysop
preference/configuration.

This allows us to use dstrtounix() for MM/DD/YY dates regardless of the system
configuration (sysop/locale preference).

This fixes issue with QWK route.dat file and door.sys (expiration date)
parsing where the date is/has-to-be in MM/DD/YY format, always.

"01/00/00" would get parsed/converted back to Jan-1-2000 (usually), which is
usually not what we want.

Although we've added (in SBBS v3.20) configurable numeric date input/display
formats for the system, the output was still ambiguous for users (e.g.
NN/NN/NN which could be interpretted a number of ways), so I've added an option
to choose "verbal" short date formats to be displayed where possible instead.
The same value separate from the numeric format (whatever the sysop chose) is
used in the verbal date output, but since month name abbreviations are 3
characters, only one separator is used (to keep the output length fixed at 8
characters).

The new "Verbal" short date display format is choosable in the SCFG wizard and
via SCFG->System->Short Date Format.

To complete the request from: Max (WESTLINE)

  Is it possible to do a new dateformat in scfg
  In sweden we using YYYY-MM-DD format as standard.

The default will be '/'.  Technically, any separator is possible by editing
the "date_sep" value in the global section of main.ini.  SCFG allows the
most popular separators: /.- and space.

... and YYYY/MM/DD for birthdate input/display.

Now set in SCFG->System (not toggle options) and stored in the "date_fmt" key
(new) in main.ini. The old sys_misc SM_EURODATE flag is deprecated (but used
to determine the default value of date_fmt when not present).

Generates a "Dd Hh Mm" string from a specified number of minutes.

This macro has expanded to nothing for a while now and even before, the usage was misguided and unnecessary as explained in this video: https://www.youtube.com/watch?v=cjotPqQxxAY

The goal of this commit is that: only modules that either are part-of sbbs.dll/libsbbs.so or need to link with/use that library, will #include "sbbs.h" and thus be dependent on its subsequent includes (e.g. cryptlib.h, jsapi.h). This should mean extdeps.mk can be trimmed way down.

I also removed CVS keyword/comments and trimmed up the boilerplate copyright notice in modified and added source/header files in this commit.

There is no functional change in behavior in this comment.

I'm fed-up with MSVC assertions in ctype functions (e.g. isdigit, isprint, isspace, etc.) when called with out-of-range (e.g. negative) values.

This problem only affects MSVC debug builds, but if you run them (like I do), these things are like little time bombs that can drive you crazy (knocking your board out of service).

The new macros names are bit more descriptive as well.

- Never ban the server's own address
- Log the login attempt and last name attempted
- Use a compressed version of the HH:MM:SS "time remaining" portion of the log

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

file (msgdate) so that modules that use date_str.c will not require smblib too.

the '+' char (e.g. +0700).
Fix for rfc822date(): now correctly parses (theoretical) negative timezone
offsets that have a non-zero minutes field (e.g. -0430).
Fix for msgdate(): all RFC822 timezones are now represented in numeric
offset format (per RFC1123).
