This commit (obviously non-atomic) cleans LIEF's code base by:
- Using pointer semantics (`std::unique_ptr<>`)
- Using LEAF boost error in the binary stream
- Reducing the scope of the iterators (`it_section`, ...)
- Removing `Structures.hpp` from the public headers
- etc
API Changes:
LIEF::MachO::Parser won't return a 'std::vector' of MachO::Binary*
but a pointer to MachO::FatBinary object
It's a kind of wrapper on std::vector<MachO::Binary*>
