BNetworkAddress: Make the first SetToLinkLevel() take a const pointer.

Technically breaks ABI. However to the best of my knowledge,
nothing uses this method outside of the tree.

use .IsSet() instead if .Get() != NULL

NetworkAddress: Fix things yet again.

If I had used my head instead of blindly c&p'ing the suggested code
from Axel's message, I would have realized that Unset() unsets fStatus
too. Not a bright thing to do on my part...

BNetworkAddress: Fix review comments (again).

Axel changed his mind about the status on Unset(), and I messed
up the fStatus setters.

BNetworkAddress: Address review comments.

Thanks Axel and Rene!

BNetworkAddress: Fix setting fStatus all over the place.

Add a simple DNS caching system to BNetworkAddress

netresolv (and libbind) won't cache DNS requests, which can result in a
lot of DNS requests being made for the same host. Implement a simple
cache in RAM (local to each application) which will keep the most
recently requested addresses cached. This can speed up loading of an
HTTP page a lot, by saving a DNS request for each resource stored on the
same server as the main page.

BNetworkAddress::IsEmpty() now detects empty ipv4/6.

* Until now, only AF_UNSPEC addresses could be empty.
* Now, the unspecified IPV4/IPv6 address is considered empty, too.
* This corresponds to how the kernel modules handles this.

Revert "Move getifaddrs to libnetwork again."

This reverts commit 31ea76548a64b232ed10cb444bf84ca1f7e40b0f.

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

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.

libnetapi: second pass of style cleanup

* remarks from Axel

BNetworkAddress: accept NULL link address strings.

* Reverted back to the original version of BNetworkAddress::SetAddress();
in_addr_t is now in network endian again. Thanks, Philippe!
* Made SetToLoopback(), and SetToLocal() a bit more useful (although the latter
isn't implemented yet).
* Minor cleanup.

know how I implement that function :-)
