Juergen Ributzka 6dbc6445b5 [TextAPI] TBD Reader/Writer
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

Update: This contains changes to fix issues discovered by the bots:
 - add parentheses to silence warnings.
 - rename variables
 - use PlatformType from BinaryFormat
 - Trying if switching from a vector to an array will appeas the bots.
 - Replace the tuple with a struct to work around an explicit constructor bug.
 - This fixes an issue where we were leaking the YAML document if there was a
   parsing error.

Updated the license information in all files.
