Add a helper to allow loading an image within specified address range.
This will be used to load multiboot2 images later.

On PowerPC64 ABIv2 we need to look at the symbol to determine
if it has a local entry point. Pass struct mem_sym into
machine_apply_elf_rel() so we can.

- Widen some types. Why did I use unsigned long? I guess this
code predates the decision to support biarch.
- Since I have made the types wider fix the statements that
print those types out.

o With relocatable kernel in picture, the kernel text map offset
(__START_KERNEL_map) is no longer constant. It depends on where kernel
is loaded.
o Now /proc/kcore is read to determine the virtual address the kernel
is mapped at and /porc/iomem is read for determining the physical
address where kernel is loaded at. This information is enough to
create to fill virtual address and phy addr info for elf header
mapping kernel text and data.
o Virtual address for kernel text are needed by gdb as well as crash to
retrieve the meaningful data from core file.
o This patch requires "elf note memsz" fix in the kernel. Currently
that fix is in -mm tree. It will still work with older kernels. It will
display the warning messages (/proc/kcore could not be parsed) and hardcode
the kernel virtual address and size.

o Adding a new parameter to elf functions. This flag can be used to alter
the function behaviour. Currently only one bit is being used for skipping
the elf file len check while builing the elf info.

o Fix the logic to load a the files of type ET_DYN. Helpful in loading
the relocatable kernel to a different address than the address
executable is compiled for.
