This adds various new functionality and cleanup surrounding the use of the Stream library. Major changes include: * Renaming of all classes for more consistency / meaningfulness * Addition of some new methods for reading multiple values at once. * Full suite of unit tests for reader / writer functionality. * Full set of doxygen comments for all classes. * Streams now store their own endianness. * Fixed some bugs in a few of the classes that were discovered by the unit tests. llvm-svn: 296215
