9503f2fc7b Add relocation in the Abstract layer
The abstracted attributes are:
  * Address: virtual address where the relocation occurs
  * Size: size in bits of the relocation

See: LIEF::Relocation / lief.Relocation and abstract_reader

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)

907e853b18 Fix some ambiguous API (fix #27)
PE::Binary::get_content_from_virtual_address can now take either:
  Absolute Virtual Address / Relative Virtual Address

In the PE Python API:
  * Merge 'PE.parse_from_raw' and 'PE.parse'
  * Change 'PE.Binary.section_from_virtual_address' to 'PE.Binary.section_from_rva'

In the PE C++ API:
  * Change 'Binary::section_from_virtual_address' to 'Binary::section_from_rva'

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
