I noticed that more than one caller of smb_open_sub() would not call
smb_create() if the sub had not been previously "created" and in some of the
instances where they did call smb_create(), if create failed, the message base
was errorneously left open. So just do the create here to elmiinate the chance
of error (forgetting) and redundancy of logic.

center the xim in the resulting window and fill the rest with black.

Resize the xim if the window isn't scaled.

The xim wasn't scaled to the new size (ever)

be expanded if people like it... this can be used to store and replay data,
making sprites a lot easier to implement client-side.

Because the test to continue is *after* the loop, we can't continue
when c is the last index into lzh->son, or the code will make use of
lzh->son[sizeof(lzh->son)/sizeof(lzh->son[0])] which is outside the bounds
of the array.

Fixes coverity warning in SyncTERM... matches the size all callers currently
use.

easily result in a message body being added to a message base with no
accompanying message header: if the header data was 0-length, the hfield_dat
was not actually allocated and the applicable smbmsg_t convenience pointer was
not set accordingly. This had the side effect that if a message were to be
imported with a blank recipient ("To" field), the header was not created at
all (to support mutliple header, single body msgs, i.e. bulkmail).
The other functions that set the convenience pointers do not treat 0-length
header field data special, so this was inconsistent behavior.
Most message types (e.g. networks) don't want 0-length "to" fields, but that
shoudl be enforced somewhere else, not here.

So on Windows, calling unlock() on a file region that you don't have locked,
incurs a delay. Likewise, calling lock() on a file region that already have
locked incurs a delay. These delays were seriously throttling message imports
on Windows (e.g. importing echomail or QWK packets). What should take a few
seconds, was taking minutes with noticeable delays. This code has been
performing redundant locks/unlocks for over 15 years, so I can only conclude
that the performance penalty is a new behavior introduced in recent version(s)
of Windows.

The area change feature now uses DDLightbarMenu.  There is no more internal lightbar code in this message reader. This requires the latest dd_lightbar_menu.js (in sbbs/exec/load).

Screen refresh optimization: Only do PageUp and PageDown if not already at the top or bottom of the menu items.  If already there, don't redraw the menu items.

MSS for the packet size.

Fixes problem with telnet server where large transfers were full packets
followed by a 12 byte packet.  Also removes hack in webserver that always
assumed timestamps were enabled.

The Win32 code has not been tested, but is assumed to work perfectly.

You're welcome.
