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

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'.

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.

special support for PHDR segments and segments which include the elf header
...
Only elf files with strange GNU_RELRO segments fail the load, save, cycle.
It would maybe a good idea to separate the layout functionality from the
current save. The current coupling of layout and save make it
impossible to build layouts which contain the elf header via the public
API.

separated layout generation and saving
...
Many example elfs (hello_32, hello_64, asm ...) require that the
first section directly follows the program header table. The
section header is then placed between segments or at the end.
This change prepares the late placement of section header table.

changed order in which the sections are emitted

The fact that segments can contain header information as well as
sections requires that sections within segments are emitted first.

rewrote the segment save logic to not only care about alignment
...
The initial implementation only made sure that all sections and segments
are properly aligned. This is enough for simple embedded applications
but can not deal with more complex layouts.
The new implementation should be more generic given that it respects the
virtual addresses of the individual sections.
One thing which is currently not supported by this rewrite are segments
which contain the program/segment header or even the whole elf header.

fix: static class member MAX_DATA_ENTRIES is not defined -> linker error
...
Static class members usually have to be defined explicitly which plays not
well with header only libraries. Moving the constant into the ELFIO scope
works around that problem.
The problem only shows up at -O0. Higher optimisations levels manage to
completely remove the references to the static member.
