Fixed up network stack and drivers for x86_64.

* Various compilation fixes.
* Fixes to the FreeBSD compatibility layer (from comparing the x86-
specific bits with the equivalent amd64 sources in FreeBSD).
* Compile all the Ethernet drivers except for sis900 and wb840, these
require a bit more work to fix (will file a ticket soon). Tested
ipro1000 and rtl81xx, no issues.

* Improved the output of the "net_domains" KDL command.

* Reworked the complete stack to allow more than one address per network
interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
complete, though, InterfaceAddresses need to hold references to their
interface as well).
* There are two known regressions of this commit that I will fix later:
- you cannot remove interfaces anymore
- IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.

* We need to invalidate all routes belonging to the interface when removing it.
* This fixes the second problem mentioned in bug #6243, and therefore the bug
itself.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37692 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made the stack send out interface change notifications where needed (at least
hopefully :-)).
* Improved interface change notification to include the flags that changed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37594 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made some internal lists use DoublyLinkedLists instead of struct list.
* Added a few KDL commands to improve your debugging experience.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35469 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Locking order dictates that this lock is an inner lock, and shouldn't
be used everywhere.
* This also fixes a panic when deleting interfaces (an already deleted
lock was unlocked).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29902 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The net_domain's lock is now a recursive lock.
* Fixed all route locking problems, of which there were numerous
({add|remove}_route(), and list_routes() did not lock at all). Added
lock assertions in functions that don't do the locking themselves.
* A route will now be removed from the list in remove_route(), not in
put_route_internal(). Before, a route could easily be removed twice, causing
remove_route() to release references it did not own. This fixes bug #2706.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29386 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Cleanup, improved comments, removed useless ones.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29232 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28830 a95241bf-73f2-0310-859d-f6bbb57e9c96

* More or less completed the network notification module - it does not remove
old invalid user listeners yet, though (ie. if a team dies).
* Implemented userland network monitor functions.
* Added a few notifications to the network stack, even though this part isn't
complete yet (especially notify_interface_changed()).
* Added optional debug output to the notifications module.
* Added the module to the image, it basically works now (tested).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28825 a95241bf-73f2-0310-859d-f6bbb57e9c96

without having the domain locked seems to be safe AFAICT.

net_device_interface: remove redundant fields

whenever an interface is deleted, call put_domain_datalink_protocols() so all readers are unregistered.

- Unfortunely this requires RX lock to become a recursive lock.

moved IFF_LINK handling to the device module (ethernet in this case). Now domain interfaces only keep specific flags such as IFF_UP and the configuration flags. IFF_LINK, IFF_BROADCAST etc are maintained exclusively by the device.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20612 a95241bf-73f2-0310-859d-f6bbb57e9c96

a bit more work towards proper locking including a fix to a refcount bug

- fixed a issue in add_interface_to_domain where the device interface's refcount was always incremented since that function was getting the device interface handle and not returning it unconditionlly
- if the ethernet device goes down, and the fd is close()ed, return B_FILE_ERROR instead of calling into the driver again


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20601 a95241bf-73f2-0310-859d-f6bbb57e9c96

started some work to properly handle device_removed() and setting interfaces down in general.

- remove all routes that use interfaces going down.
- when a device is going down, remove associated domain interfaces.
- interfaces weren't getting a properly referenced device interface, fixed.
- down call down_device_interface when deleting a interface, instead set it down and let the upcounts do its job.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20600 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed ETHER_GET_LINK_STATE ethernet driver interface, added ETHER_SET_LINK_STATE_SEM.
* The device interface list now uses class DoublyLinkedList instead of struct list.
* Implemented SIOC[SG]IFMEDIA for setting (not supported by any device yet), and
retrieving the device media information.
* Fixed a locking bug in list_domain_interfaces().
* Added new stack function device_link_changed() that should be called in case the
link state (media) changed.
* The ethernet device module now spawns a thread and will periodically check the media
state of all ethernet devices that support this (if any).
* Minor cleanup.
