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]

3c5620d46d Make note section entries for 64-bit ELF file be the same as for 32-bit file 
There are discrepancies in documentations. SCO documentation
(http://www.sco.com/developers/gabi/latest/ch5.pheader.html#note_section)
requires 8 byte entries alignment for 64-bit ELF file,
but Oracle's definition uses the same structure
for 32-bit and 64-bit formats.
(https://docs.oracle.com/cd/E23824_01/html/819-0690/chapter6-18048.html)

It looks like EM_X86_64 Linux implementation is similar to Oracle's
definition. Therefore, the same alignment works for both formats

e3e0d6dbdb Fixed off-by-one error in 'name' of add_note() function. 
Previously, when assigning 'name' as a string, it's length was specified
using the full length of 'namesz'. However, this length includes the
trailing '\0' of the underlying char[]. This ultimately causes the C++
string that is created to (incorrectly) contain the '\0' character as
well. This leads to problems where e.g. the following will return false,
even when 'name' itself actually contains the string "GNU\0":

  if (name == "GNU") {
    return true;
  }
  return false;

To fix this, we should only include the length of the string minus the
trailing '\0'.

91e61ec4b2 use the NULL section instead of offset == 0 
This change makes it possible to use the regular API to build up
elf files which include the file header.

1676247836 fix alignment of segments during saving -> copied elfs are working 
The old implementation aligned the segment start. However, the
intended behaviour is to align the offset and the vaddr
(p_vaddr % p_align == p_offset % p_align). This is required for the
loader which can then operate on memory pages.
