The BNetworkRoute class manages a route_entry and the sockaddr's
associated with it. It replaces the direct use of route_entry in the
BNetworkInterface API.
Using route_entry is fragile and inconvenient as it only holds pointers
to the sockaddr's. When getting a list of routes from the kernel, each
route_entry is set up so that its pointers point into the single flat
buffer that is passed around. Creating a copy of the route_entry and
then deleting the flat buffer makes the pointers in the copy stale.
Returning these route entries therefore always lead to a use-after-free
when they were eventually used.
BNetworkRoute also takes over the code and functionallity of getting
routes from RouteSupport. The corresponding method in BNetworkRoster is
replaced by a static method in BNetworkRoute.
Also distinguish between the default route and gateway of an interface.
GetDefaultRoute() now gets the default BNetworkRoute for the interface
while GetDefaultGateway() gets the associated gateway address within
that default route. Adjust network preferences panel to this change.
Note that we currently only seem to have per interface default routes
and not an actual global default route. This was already the case before
these changes and I did not further investigate what this means.
Implement BNetworkRoster::GetRoutes() and BNetworkInterface::GetRoutes().
Also implement BNetworkInterface::GetDefaultGateway().
There is code duplication at the moment, and the api only supports IPV4.
BNetworkRoster::{Count|GetNext|Add|Remove}PersistentNetwork() as it fits
better (thanks Philippe for the heads up).
* Implement the backend for these functions in the net_server and also move
conversion of the wireless_network based format into the settings based format
there.
* Implement removal of a network from the settings and make adding a new network
with the same name replace the old one instead of just adding multiple ones.
Might need to change this in the future depending on how we want to handle
multiple networks with the same name (i.e. distinguish based on BSSID or
similar).
* Fix apparent oversight that caused configured networks _not_ to be used in the
auto join attempt.
* Remove auto joining open networks. I've been bitten by that more than once now
because we happen to have an open network in the neighbourhood that I now
accidentally used to transfer quite a bit of (unencrypted) stuff before
noticing... In the future, one will instead have to explicitly join an open
network once and store that config. Note that the driver will actually still
auto-associate with open networks due to how things are set up currently.
Note also that the auto join will fire join requests whenever there's a
disassociation event, so you might see spurious join dialogs when the
wpa_supplicant actually just re-establishes the connection.
* Make join requests async again. Instead of waiting for a synchronous reply of
the wpa_supplicant we instead return success when the request has been sent.
While the API call might still be made synchronous again in the future, the
net_server should really not block on an external application. In the case of
the wpa_supplicant we would otherwise deadlock when using the new
*PersistentNetwork() API after a successful join, and in other cases we might
just unacceptably delay other calls.

untested at this point, though.
* Will port ifconfig, NetworkStatus, and the Network preferences application
later in order to test the API.

know how I implement that function :-)
* Cleaned up libbnetapi.so Jamfile, removed non-Haiku target code.
* Added empty files to the build to see that the headers are compiling.

started implementing it yet, anyway).
* Note that BNetworkAddress is supposed to replace BNetAddress -- the latter
does not provide enough space for a struct sockaddr_storage, and has a very
IPv4 specific and incapable API, anyway.
