Thanks to Tek1 for the clues in locating this one.

Consider doing the same for all .h files.
Consider the meaning of sanity.

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.

all files linked with load_cfg.c.

Created IS_PATH_DELIM() macro (stole websrvr.c->is_slash macro).
Defines BSD _PATH_TMP and _PATH_DEVNULL macros for all platforms.

Created sbbs_t::signal_sub_sem() method to handle creation of global
echomail_sem (for FTN sub-boards) and the sub-boards post_sem (if confiugred).

timezone value (for display purposes only).

in the file (uses default attribute of high intensity white). Allows upgrade
from v2.x without overwriting attr.cfg.

grp/lib code prefix (helps generate unique internal codes).

module (.js or .bin) files.
Removed temporary Unix-compatibility hack of converting to lower case:
standard directory paths and loadable modules (which are already lowercase
in the default .cnf files).

or longer, uses a passed 'buflen' parameter to determine the truncation point.

allowing additional sysop-configurable color attribute definitions.

(64) to 48.

- used to specify a physical parent directory for all logical directories in a
file library (convenient for CD-ROMs and other large directory configurations).

Fixed prep_dir() for use on FreeBSD - _fullpath (macro for realpath) initializes the entire MAX_PATH bytes of the destination string.

TEXT.DAT  lines are now allocated with one additional byte and zero-filled for the new YNQX line (was just YN), for backwards compatibility.
