When a process that has registered one or several binder services with
the service manager crashes, that process will usually be restarted by
init (see init.rc). When the process comes back up, it will attempt
to re-register itself with the service manager. However, the binder
driver may not deliver the death notification to the service manager
before the the new service-registation request, in which case the
service manager will reject the request as a duplicate.
The same may occur if a process takes a while to actually exit. Since
the init language's restart command does not wait for a process to
exit before restarting it, there may be for a brief instant two
processes. The new one will attempt to register before the old
one has exited, causing the same problem.
This patch does not treat duplicate registrations as an error.
Instead, the service manager force-releases the old instance and
proceeds with registering the new instance of a service.

NFC service is now an application service in packages/apps/Nfc.
NFC service is registered through ServiceManager.addService(), and the proxy
object NfcAdapter obtains a handle to it through ServiceManager.getService().
**Important** Had to add new symbols AID_NFC / NFC_UID / android.uid.nfc and
modify service_manager.c, Process.java and PackageManagerService.java in order
to force the com.android.nfc process to take a fixed uid, so that it can use
ServiceManager.addService().
Most of the JNI has moved to packages/apps/Nfc/jni. However NdefRecord and
NdefMessage require some in-process native code, so android_com_NdefMessage.cpp
and android_com_NdefRecord.cpp stay in frameworks/base/core/jni. They link to
a very small library libnfc_ndef.so that implements NDEF message parsing. This
has been added to core.mk so all devices (even without NFC hardware) can work
with NDEF data.

This is (intendend to be) a no-op change.
At this stage, Binder RPCs just have an additional uint32 passed around
in the header, right before the interface name. But nothing is actually
done with them yet. That value should right now always be 0.
This now boots and seems to work.
