libbnetapi: Add BNetworkRoute to replace use of route_entry.

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.

NetworkInterface.h: honor 80 character limit.

Revert "Move getifaddrs to libnetwork again."

This reverts commit 31ea76548a64b232ed10cb444bf84ca1f7e40b0f.

Adrien, please try again without clobbering the otherwise nice
BNetworkInterface API!

Conflicts:
src/kits/network/getifaddrs.cpp

Move getifaddrs to libnetwork again.

* BNetworkInterfaceAddress is moved to libnetwork. It is modified to not
use BNetworkAddress (which is in libbnetapi) and instead use sockaddr
and sockaddr_storage directly. All callers are adjusted to this.
* Some support code is shared between BNetworkInterface and
BNetworkInterfaceAddress, move it to libnetwork but in the BPrivate
namespace.

Added family parameter to the GetRoutes() API.
Moved common code to a private file.

Network route API: Second try (WIP).
Implement BNetworkRoster::GetRoutes() and BNetworkInterface::GetRoutes().
Also implement BNetworkInterface::GetDefaultGateway().
There is code duplication at the moment, and the api only supports IPV4.

* Added methods to manipulate routes.
* Added AutoConfigure() method.
* Implemented missing Index() method.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39592 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added convenience methods FindAddress(), and FindFirstAddress().
* Added BNetworkInterfaceAddress::Destination() as synonym for Broadcast()
(depending on the configuration, it could be either one).
* Media() will now return -1 in case of an error.
* Added "const" where it makes sense.
* Added convenience functions for AddAddress(), and RemoveAddress() that only
take the actual address.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38060 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38024 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Adapted API as needed, and implemented most of the C++ API - it's completely
untested at this point, though.
* Will port ifconfig, NetworkStatus, and the Network preferences application
later in order to test the API.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37988 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Adapted headers after Stippi's suggestions - I won't add the const until I
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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37942 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced first draft of a C++ network API. Comments welcome (I haven't
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.
