Init-task names for sparc64 (that's the final one, whew).

sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.

sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree

Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.

Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.
Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.

Add balloc() (a.k.a boot allocator):
- balloc() only needs to know how to allocate memory.
- Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself.
- make kernel aware of boot allocations
More work on OFW device tree:
- use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree
sparc64 boot:
- pass OFW device tree root node pointer to kernel

sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places
OpenFirmware work:
- two new functions for walking the device tree
Generic boot loader work:
- added basic string functions
Usual pile of indentation and formatting fixes.

Remove OpenFirmware calls from kernel/ entirely.
Switch the sparc64 port to use bootinfo.
Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.

Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.
Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.
Move ALIGN_UP to generic part of boot/.
Change header guards in several places so that they don't contain double underscore.
