Created DLL-exported msg_client_hfields() in postmsg.cpp as a common function
to add these client tracking header fields.

smb_read() will now retry the read operation if the read fails with an errno of
DEADLOCK (occurs on Unix if a Win32 system has the bytes already locked).

the same message simultaneously.

Added support for JavaScript mail processors configured in mailproc.cfg
with "?scriptname". See ctrl/mailproc.cfg and exec/mailproc_example.js for
details.
Some cosemtic changes to log entries.
Bugfix: if a mail processor rejected a message, the server could segfault if
the sending server reset the session or attempted another message. Also,
temp files (recipient list and msg text) would be orphaned in the data_dir.

recycling without using semaphore files.

back to callback functions (e.g. lputs, thread_up, etc). This allows servers
to share the same callback functions, eliminating many nearly-identical
functions. This was able to shave quite a bit of redundant code from ntsvcs.c.
This feature is not utilized in sbbs (sbbscon.c) or sbbsctrl (mainformunit.cpp).

smb_hfield_append_str() used for creating and appending ASCIIZ header fields.
These functions handle the string-length calculation automatically.

Adding destination nettype and address for QWK-routed SMTP mail.
Added support for mail processing command-line specifers: %h, %i, and %u
(see ctrl/mailproc.cfg for details).
Fixed %v (version specifier).

Added support for routing to QWKnet uplink (e.g. vert!digital.man@youraddr.com)

to track down the issue, I finally gave up... as a result, there is a new
feature!

Linux will no longer completely drop it's root privs (It never really did
anyways, and you couldn't possibly make it... but now it does so even less)

As a result, Linux can now recycle all servers when running as non-root.

From a security standpoint, doing this is more secure than running as root,
but less secure than the behaviour on POSIX.4 compliant pthreads.  Running
the BBS as root means that if a user can create a file with the name of his
choice, or pass *any* command through to a shell, that user will get root
access to the machine.  Using the new behaviour, the user would need to
trick the Synchronet binary itself into executing arbitrary and specially
crafted code... probobly using the dreaded buffer overflow... of which
there are probobly some in the web server code.  :-)  If the user can do
this much more tricky feat, then the user gets root privs.  If not, the
user will have to find something else to exploit on your system.

Knowing that some *BSD users (surely not OpenBSD users though) will want to
trade security for convenience, I stole a page out of the Sendmail book and
implemented a "DONT_BLAME_SYNCHRONET" make option.  Compiling like this:
gmake DONT_BLAME_SYNCHRONET=1

Will implement this same behaviour on non-Linux platforms.  Allowing this
partial security feature.

(doesn't yet work for routing to uplinks).
