(using gethostname).

files in the format: ctrl/<action>[.host][.service].
Examples:
* ctrl/recycle - recycle all services on all hosts
* ctrl/recycle.vert - recycle all services on system with hostname "vert"
* ctrl/shutdown.vert.telnet - shutdown telnet service on vert only
[service] can be "telnet", "ftp", "mail", "web" or "services".

The old recycle semaphore filenames (e.g. telnet.rec, ftpsrvr.rec, etc.) are
still supported for backward-compatibility.

type semaphore files (and possibly others in the future) for the different
servers (e.g. telnet, ftp, etc.).

Add more lprintf() logging.

specified e-mail address.

(e.g. "user@addr") into an SMB net_type (or NET_NONE for local e-mail).

Prompts the SysOp for system password.
If a valid username is sent and IP is not in rlogin.can and the local username
wasn't the correct password, prompt for password.

Decrufting.
Fix send_headers() to return if using HTTP/0.9
Added a few comments.

from NetBSDs compat library.
Also, it's not new if the If-Modified-Since and Last-Modified times are
equal.

Speed options. The NAWS option is particularlly nice as we don't need ANSI
cursor posistion reports to auto-detect screen size. If the user's account is
configured for auto-screen length detection and using a telnet client that
supports NAWS, the screen length will be dynamically updated (!).

and added TELNET_MODE_OFF definition (to detect non-Telnet, e.g. RLogin).

tracks state of local *and* remote option modes to prevent redundant requests
and responses, etc. Should be very robust now.

Use sizeof() instead of explicit sizes where appropriate
Expand buffers to MAX_REQUEST_LINE+1 to allow for the terminator
Made char buf[] a magic bumber size since it has nothing to do with headers
and is in facta binary buffer, not a string buffer.

snprintf() behaviour!

(getting tired of typing "memset(var,0,sizeof(var))").

Bugfix: flagging a node for "re-run"  (e.g. when saving changes in SCFG)
recycles the server , rather than just reloading the .cnf files.
This fixes the problem with JS events not running (even crashing) after a
rerun/reload without recycle.

* using scfg.data_dir before calling load_cfg()
* using stftime(%G), which isn't supported by MSVC
* using too small a buffer for the time portion of the log string
* thread leak: http_logging_thread() would wait forever on log_sem
  (never terminate)

Fixed bug in read_mime_types():
* wasn't resetting mime_count (e.g. after recycle)

Added missing socket descriptor to many lprintf() calls.

Fixed bug regarding checking recycle semaphore file (websrvr.rec) date/time
(wasn't initializing the "initialized" timestamp variable).
