Modified the copyright year range in code, and corrected "int32_tel"
into "Intel" in two "hypervisor/include/debug/profiling.h" and
"hypervisor/include/debug/profiling_internal.h".

This patch is to eliminate a code scan warning.
p_elf_header32 was given a value when it was declared, but later it was
given the same value again. Just remove the later one.

Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

This is a simply implement for the 32bit and 64bit elf loader.
The loading function first reads the image header, and finds the program
entries that are marked as PT_LOAD, then loads segments from elf file to
guest ram. After that, it finds the bss section in the elf section entries, and
clear the ram area it points to.
Limitations:
1. The e_type of the elf image must be ET_EXEC(executable). Relocatable or
dynamic code is not supported.
2. The loader only copies program segments that has a p_type of
PT_LOAD(loadable segment). Other segments are ignored.
3. The loader doesn’t support Sections that are relocatable
(sh_type is SHT_REL or SHT_RELA)
4. The 64bit elf’s entry address must below 4G.
5. The elf is assumed to be able to put segments to valid guest memory.

This patch adds a function elf_loader() to load elf image.
It checks the elf header, get its 32/64 bit type, then calls
the corresponding loading routines, which are empty, and
will be realized later.
