Use the nice macro to declare once-init control objects, like good little coders should.  Otherwise the initialization routines never run on Mac.  TODO:  Investigate how this was broken.

Update MSVC project files for recent changes.  Added new projects for libprotobuf-lite and the lite test.

Remove two empty source files.  This doesn't actually have any effect on code size but might as well get rid of them.

TODO:  Compile conditionally?  Provide a way to omit ExtensionSet?
  Should libprotobuf depend on libprotobuf-lite instead of being a
  stand-alone lib?

C++ and Java.  See CHANGES.txt for more details.

Fix problems with emacs protobuf mode, I guess.  See <http://www.opensubscriber.com/message/emacs-devel@gnu.org/7155093.html>.  Patch from domq@google.com.

Fix compile error on Cygwin, where int32 is typedefed to long instead of int, and the compiler can't figure out which overload of this method to use in that case.

(takes too long).

Add second run of cpp_unittest which verifies that descriptors are constructed lazily.  This is accomplished by avoiding any use of descriptors while testing a bunch of other operations, then checking at the end that descriptors have not been constructed.

Add test verifying that protoc accepts trailing backslashes on Windows, which some users claim doesn't work.  Seems to work on my machine.
