(warning fixes).

Needs a line-ending too, to support multple file requests in a single .req
file.

Move the common outbound directory creation logic into a function.

cause of Robb Starr's reported "ERROR: 400 Bad Request" problem.

to glyphs found in the Courier New font. When mapped to code points not present
in the monospace/courier font family, a different (proportional) font is used
which messes up the "ANSI graphics" display.
- 0x10 is now mapped to U+9658 (black right-pointing pointer) instead of U+9658
  (black right-pointing triangle)
- 0x11 is now mapped to U+9668 (black left-pointing pointer) instead of U+9664
  (black left-pointing triangle)
Incidentally, 0x1e and 0x1f were already mapped correctly.

Also fixed:
- 0x16 now maps to U+9604 (lower half black) instead of U+9644 (black rectangle)

Added some helpful comments (hex values, ASCII values).

on Windows XP now.  At the very least, it will now require MSVCR80.DLL.

used to, that is, it stores the broken-down date/time values in the time_t
equivalent for the local timezone, regardless of what value is in the zone
element of the xpDateTime_t.

_mkgmtime() however didn't appear until MSVCR80.dll, so the current use of
MSVCRT.DLL is broken and SyncTERM won't build.

testing the Host value (vhost value already has port stripped).

Zero-length host names are not legal either.

never worked.

If "syslog" is passed as a command-line option, always send log output to
syslog, even when not daemonized.

- the socket could be (and sometimes is) already disconnected.

a socket (and returns void), but mxlookup.c did not know this because it had
its own prototype for this function (lazy, I know).
- moved the prototypes for mail_open_socket and mail_close_socket to mailsrvr.h
- use socket() to create the (single) socket (is not a multisock, does not do
  IPv6)
- this was the cause of the "getting socket option type" errors in the
  error.log that began showing up recently. Good thing it had a "LOG_ERR"
  log level or I probably would not have noticed for a long time. :-)

rather than send the zero bytes.

to the local timezone equivalent (not adjusting for offset). Now using timegm()
(aka mkgmtime()) to fix this scenario. Times in zones other than the local time
zone or UTC are explicitly not supported by this function now (returns
INVALID_TIME in that scenario).

equivalent to sane_mktime() for broken-down date/time's in UTC.

from xpdatetime.c to support more date string formats (e.g. the JavaScript
Date.toISOString() format).

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.

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.
