Initial source checkin.
The source files were determined by building net_unittests in chromium's source tree. Some of the obvious libraries were left out (v8, gmock, gtest). The Android.mk file has all the sources (minus unittests and tools) that were used during net_unittests compilation. Nothing builds yet because of STL but that is the next task. The .cpp files will most likely not compile anyways because of the LOCAL_CPP_EXTENSION mod. I will have to break this into multiple projects to get around that limitation.
