Many changes. Binary stubs produced by this tool are now linkable in the small subset of test cases I've tried.

Added:

- .dynamic, program headers.
- Support for weak symbols.
- Support for DT_NEEDED entries.

TODO:

- Coding style hasn't been fixed. [1]
- Currently not using FileOutputBuffer.
- Program header implementation subject to change.
- Not updated to match the initial patch's change in structure/naming/etc. [1]
- Needs more tests. [1]
- Many more TODOs listed in the code.

[1] These will be addressed as pieces of this patch are upstreamed.
