- Modify bin.gypi to ensure that the io library and patch files are read directly from the sources. Remove the source buffer generation step in the gypi files for all the io library and patch files. - Restructure the code a bit to eliminate some code duplication. - Delete runtime/tools/concat_library.py R=ager@google.com, sgjesse@google.com Review URL: https://codereview.chromium.org//14752008 git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@22514 260f80e4-7a28-3924-810f-c04153c831b5
