Add basic infrastructure for reading and writting TBD files (version 1 - 3). The TextAPI library is not used by anything yet (besides the unit tests). Tool support will be added in a separate commit. The TBD format is currently documented in the implementation file (TextStub.cpp). https://reviews.llvm.org/D53945 llvm-svn: 347808
