dylib link demo

A demo to show how to build and run a Rust based program depending on a Rust library which needs a C shared library.

Quick Test

1. make oldadd: this create a C shared library called libadd.so in ./demo
2. make build: build the Rust project by adding linker arguments by -C. Should create the executable successfully.
3. make copy: copy executable and library file into test_dir to create a test environment
4. make dir_test: run the program with LD_LIBRARY_PATH=./lib. Should be successful. output: c_add_foo: 1
5. make newadd: create a new shared library using newadd.cxx
6. make copy_new: copy the library to the target position
7. make dir_test: output: c_add_foo: 2. The program loads the correct shared library.
