kernel/arm: Fix a few build regressions around types

Change-Id: I577e64397610bc48e4b7646c533de95d0024dd63

Style fixes to various parts of the system.

This patch was never applied after GSoC 2012. Rebase the parts that
still apply so we can close the ticket.

Fixes #9490.

system: Build using public elf.h header

Reduce duplication of code by

* Removing from elf_common.h definitions available in os/kernel/elf.h
* Deleting elf32.h and elf64.h
* Renaming elf_common.h to elf_private.h
* Updating source to build using public and private ELF header files
together

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.

kernel arm: Quick style cleanup; No functional change

* Add support for R_ARM_ABS32 to kernel ELF linker
* Removal of some commented out (messy) code

ARM:
* Disable TRACE output of ELF relocation
* Implement R_ARM_RELATIVE (for kernel modules)

No more errors on 'loading' of kernel modules now!

* ARM: Initial stab at fixing ELF relocations (much more to do though for full ELF relocation support).

We now boot right up to "INIT: main: done... begin idle loop on cpu 0" ! :)
(Please note that there's still *lots* stubbed out)

[GSoC] [ARM] Patch by Johannes Wischert.
- stubbed out many arch kernel functions (borrowed from other archs),
- partially implement ELF relocations code, enough to load the kernel,
- move uart.c to kernel sources and use the same one for the loader,
- default implementation for gensyscalls,
- assembler code functions for interrupt masking (enable/disable/restore/query).
