*

* to check for online status, &c.
* 2. add a "long Dial(long connectionId = -1)" function which asks the user
* about which connection to dial (this may be done using native dialogs
* under NT, need generic dialogs for all others) and returns the identifier
* of the selected connection (it's opaque to the application) - it may be
* reused later to dial the same connection later (or use strings instead of
* longs may be?)
* 3. add an async version of dialing functions which notify the caller about
* the progress (or may be even start another thread to monitor it)
* 4. the static creation/accessor functions are not MT-safe - but is this
* really crucial? I think we may suppose they're always called from the
* main thread?

We first try to find out if ppp interface is active. If it is, we assume
that we're online but don't have a permanent connection (this is false if a
networked machine uses modem to connect to somewhere else, but we can't do
anything in this case anyhow).
If no ppp interface is detected, we check for eth interface. If it is
found, we check that we can, indeed, connect to an Internet host. The logic
here is that connection check should be fast enough in this case and we
don't want to give false positives in a (common) case of a machine on a LAN
which is not connected to the outside.
If we didn't find either ppp or eth interfaces, we stop here and decide
that we're connected. However, if couldn't check for this, we try to ping a
remote host just in case.
NB1: Checking for the interface presence can be done in 2 ways
a) reading /proc/net/dev under Linux
b) spawning ifconfig under any OS
The first method is faster but only works under Linux.
NB2: pinging, actually, means that we first try to connect "manually" to
a port on remove machine and if it fails, we run ping.

// Fullscreen mode:
// ----------------------------------------------------------------------------
// NB: Setting fullscreen mode under X11 is a complicated matter. There was
// no standard way of doing it until recently. ICCCM doesn't know the
// concept of fullscreen windows and the only way to make a window
// fullscreen is to remove decorations, resize it to cover entire screen
// and set WIN_LAYER_ABOVE_DOCK.
//
// This doesn't always work, though. Specifically, at least kwin from
// KDE 3 ignores the hint. The only way to make kwin accept our request
// is to emulate the way Qt does it. That is, unmap the window, set
// _NET_WM_WINDOW_TYPE to _KDE_NET_WM_WINDOW_TYPE_OVERRIDE (KDE extension),
// add _NET_WM_STATE_STAYS_ON_TOP (ditto) to _NET_WM_STATE and map
// the window again.
//
// Version 1.2 of Window Manager Specification (aka wm-spec aka
// Extended Window Manager Hints) introduced _NET_WM_STATE_FULLSCREEN
// window state which provides cleanest and simplest possible way of
// making a window fullscreen. WM-spec is a de-facto standard adopted
// by GNOME and KDE folks, but _NET_WM_STATE_FULLSCREEN isn't yet widely
// supported. As of January 2003, only GNOME 2's default WM Metacity
// implements, KDE will support it from version 3.2. At toolkits level,
// GTK+ >= 2.1.2 uses it as the only method of making windows fullscreen
// (that's why wxGTK will *not* switch to using gtk_window_fullscreen
// unless it has better compatibility with older WMs).
//
//
// This is what wxWidgets does in wxSetFullScreenStateX11:
// 1) if _NET_WM_STATE_FULLSCREEN is supported, use it
// 2) otherwise try WM-specific hacks (KDE, IceWM)
// 3) use _WIN_LAYER and hope that the WM will recognize it
// The code was tested with:
