Combine donut/eclair/eclairmr1/froyo/gingerbread source folders.

* Where relevant, call APIs directly and mark Compat APIs as deprecated
* Remove eclair-gingerbread folders from gradle and makefiles
* Bump LOCAL_SDK_VERSION to 9 in a couple of places that were skipped

In the next CL compat/donut will be renamed to compat/gingerbread.
Not doing this here to minimize the amount of diffs in this CL.
