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.
