728a2b6523 Replace broken reference ELF file for testing 
The existing ELF file was somehow seriously broken.
It's now replaced with the file generated by the current code of
ELFio, which seems to be working correctly.

So the test now serves as a regression test for future
changes.

fe78d06e81 Segment align updated when saving, not loading 
After loading, the data model in memory should resemble the original ELF file as closely as possible,
so that ELF viewers based on elfio will print out the original values, not the calculated ones.

446e0c215c elfio_note: fix MSVC compiler warning 
Fix the following MSVC compiler warning:

elfio/elfio_note.hpp(77): warning C4267: 'initializing' : conversion from 'size_t' to 'ELFIO::Elf_Word', possible loss of data

by changing the type of max_name_sizei to Elf_Xword, as
note_secton->get_size() returns Elf_Xword and note_start_positions also
contains members of type Elf_Xword.

af4140a122 elfio: don't cast away const qualifiers 
Don't cast away const qualifiers when accessing const data (e.g. section
data). This fixes the warnings such as the following when compiling with
GCC and the -Wcast-qual flag set:

warning: cast from type ‘const char*’ to type ‘ELFIO::Elf_Word* {aka unsigned int*}’ casts away qualifiers [-Wcast-qual]
