Remove semi-broken Java thread-local builder freelist 'optimization'.  Maybe bring back later in optional form.

This fixes some issues with the lite profile for the java build in which the lite jar contained the full binary.

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).
