Ryan Prichard 67a34b6c03 Build system: redo how version number tracking works
* Remove the "version suffix" and BUILD_INFO.txt mechanisms, which I
   believe no one uses except winpty itself.  Instead, a suffix can be
   added in the VERSION.txt file.

 * Instead of passing the version and commit info as a preprocessor macro
   when building every C++ file, write the info into a GenVersion.h
   header that is only included by WinptyVersion.cc.

 * Instead of writing a BUILD_INFO.txt in ship.py, pass COMMIT_HASH=<hash>
   to make.

These changes accomplish two things:

 * People who build a tag from source won't see a "<ver>-dev" suffix
   anymore.

 * Changing the version or the commit will correctly rebuild the version
   object files (and only those object files).  It will also relink every
   binary.
