Add required arch_elf_* functions for all archs

Added an ELF64 version of preloaded_image.

* There is now 2 structures, preloaded_elf32_image and preloaded_elf64_image,
which both inherit from preloaded_image.
* For now I've just hardcoded in use of preloaded_elf32_image, but the
bootloader ELF code will shortly be converted to use templates which use
the appropriate structure. The kernel will be changed later when I add
ELF64 support to it.
* All kernel_args data is now compatible between 32-bit and 64-bit kernels.

Symbol resolution functions in the kernel: Removed the unused parameter
allowing optional prepending of a string to the symbol names.

Make kernel elf loaders usable by bootloader to factor them out of it.

* Fixed a bug regarding storing/restoring FPSCR in the interrupt
code. The stack pointer was not adjusted, hence we were
overwriting the previous register value. But it looks like I
missed to check in the arch_cpu.h with the iframe structure
including the floating point registers anyway.
* Backported the ELF PPC relocation code from the boot loader to
the kernel.
* Fixed the PPC version of arch_thread_switch_kstack_and_call().
Apparently the signature had changed, but the assembly
implementation was not adjusted accordingly.
* sc prints more registers now (LR, CR, CTR, XER,...).
* Fixed several occurences of not-working fault handlers.
Apparently the compiler realized, that the "error" label was
never jumped to (by the code it knew), and optimized the
respective code away. Now we use a trick to make it think the
error label might actually be jumped to. I wonder whether the
x86 version has the same problem when being compiled with GCC4.
* Adopted the x86 page fault handling interrupt code.
