openfirmware: fix dma-alloc for sparc

The dma-alloc method is in the parent node (the PCI bus), not directly
in the network device.

openfirmware: fail if IP address can't be found

Sending packets from 0.0.0.0 doesn't work quite right, so better admit
we failed.

openfirmware: another way to find the MAC address

Of course Sun and Apple didn't put it at the same place...

openfirmware: more fixes for 64bit systems.

Gets call-method working for sparc, and fix more places where we
accidentally truncate 64bit values or sign-extend 32 bit ones.

* Fixed coding style issues pointed out by Axel.
* Fixed potential buffer overflow and fault in default-client-up code path
(OF counts terminating zero char, too).
* Added an intermediate fallback to parsing the boot path
* Added himself to the copyright holders

Patch by Andreas Faerber: (OpenFirmware network boot)
* If retrieving an IP address from the non-standard /chosen/dhcp-response

* Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

Added a mini networking stack to the boot loader. It speaks basic ARP,
IP, and UDP, as well as a home brewn UDP based protocol, "remote disk",
which provides random access to a single remote file/device. The Open
Firmware flavored boot loader automatically initializes the net stack,
searches for a remote disk, and tries to boot from it, if the boot
device is a network device (e.g. when loading the boot loader via
TFTP).

This is quite nice for developing with a two-machine setup, since one
doesn't even need to install Haiku on the test machine anymore, but can
serve it directly from the development machine. When the networking
support in the kernel is working, this method could even be used to
fully boot, not just for loading kernel and initial modules.
