Major changes (features):
* Enable adding multiple sections/segments - Executable (PIE or not), Library
* Enable adding multiple dynamic entries (DT_NEEDED, DT_INIT etc)
* Enable adding multiple relocations
* Enable adding multiple dynamic symbols
* Enable segment replacement
Major changes (API):
* Getters Binary::get_*name*() has been renamed to "name()"
* Binary::add(const DynamicEntry& entry) - To add an entry in the dynamic table
* Section& Binary::add(const Section& section, bool loaded = true) - To add a section(s)
* Segment& Binary::add(const Segment& segment, uint64_t base = 0) - To add segments
* Segment& replace(const Segment& new_segment, const Segment& original_segment, uint64_t base = 0)
* Binary's last_offset_section(), last_offset_segment(), next_virtual_address()
to have information about offset
* Binary's add_library(), get_library(), has_library() to handle
DT_NEEDED entries
Other changes:
* Binary::insert_content() - Use add(const Section&) or add(const Segment&) instead
* ELF's DataHandler has been cleaned
* Through LIEF::Section one can look for integers, strings, data
within the section (see LIEF::Section::search,
LIEF::Section::search_all)
* Through LIEF::Binary one can get *xref* of a number (or address)
see LIEF::Binary::xref function
* To access to the Abstract binary in Python, one can now use
the 'abstract' attribute. (e.g. binary.abstract.header.is_32)
