Add synopsis to x86 instructions.
Add debug lib.
Add jstring custom string utilities library.
Add sqlite_helper library.

Use sqlite3_exec in conjunction with sqlite_helper library
instead of sqlite3_prepare, sqlite3_step and sqlite3_finalize
steps. This allows for greater code reuse, shorter and more
robust code.

Add first set of unit tests (using Google Test) to intel-x86-ref library.
Add skeleton files to add similar tests to other libraries/sub-programs.
