a40da3e3b4 Enable to export and create dynamic symbols
New API:

  * Binary::{has_dynamic_symbol, has_static_symbol}
  * Binary::{get_dynamic_symbol, get_static_symbol}
  * Binary::add_exported_function
  * Binary::export_symbol

  * Symbol::visibility
  * SymbolVersion::local / SymbolVersion::global

Resolve #112

b94900ca7f Improve the ELF part of LIEF
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)

77d43f9db4 Fully handle section-less ELF binaries
* Fix #25
  * ELF `tiny` binaries are now handled (see #7)
  * Computation of dynamic symbols can be done with differents methods:
    hash table, sections and relocations. (See LIEF::ELF::DYNSYM_COUNT_METHODS)
  * ELF parser can be configured to use one of the DYNSYM_COUNT_METHODS
  * Improve tests
