Make getSystemService(NFC_SERVICE) the NFC entry point.
This gives NFC service a handle to the application context.
Deprecate NfcAdapter.getDefaultAdapter(), it does not provide a context.
Using this method will print a warning, and will later throw an exception
if a method that requires a context is called. No 2.3 API's will fail, but
new API's that do require a context might fail.
Also add helper NfcAdapter.getDefaultAdapter(Context).
