331f37d1a8 LibELF: Re-organize ELFDynamicObject::load and add PLT trampoline
ELFDynamicObject::load looks a lot better with all the steps
re-organized into helpers.

Add plt_trampoline.S to handle PLT fixups for lazy loading.
Add the needed trampoline-trampolines in ELFDynamicObject to get to
the proper relocations and to return the symbol back to the assembly
method to call into from the PLT once we return back to user code.

a18b37880e LibELF: Add ELFDynamicObject to dynamically load libaries
This patch also adds some missing relocation defines to exec_elf.h,
and a few helper classes/methods to ELFImage so that we can use it
for our dynamically loaded libs and not just main program images from
the kernel :)
