Instead of launching NFC into existing tasks, always launch
into a clean task that is owned and controlled by the NFC process.

Bug: 5122560
Change-Id: Iea6022bb754bcc46e7ab3adb1b9ccc7fe20797e3

The LLCP stack is still using globals without
holding the concurrency lock. When turning the
screen off we were previously disabling the
NFCEE routing before disconnecting the active
target. The routing code would grab the lock
and then touch the globals, which the LLCP
was using illegally, causing a crash when the
LLCP triggered callbacks are delivered.

This change reorders the shutdown at screen
off to disconnect the remote target before
issuing the change to the NFCEE routing in
an attempt to stop the ongoing LLCP
transactions, thereby avoiding the crash.
Since the callbacks are asynchronous the
race is still there, but it's hit more like
10% of the time instead of 100% of the time.

- Only hw-accelerate when we have the resources for it;
- Disallow status bar interaction;
- Remove background;
- On failure, gradually scale back up;
- On receive, slide out to the right.

This fixes the "black flashes" when starting/finishing
the NFC animation activity.

TODO:
- The status bar is "animated in" still, causing a brief white
  rectangle where the status bar is.

- Start activity instead of window overlay;
- Implement "the real twist": need to twist back to share;
- Implement receive animation (slide out);
- General cleanup.

Seems like it won't make the cut.

Backs up all NFC shared preferences. Note this only works when doing a
full system restore. Doing just a runtime restore won't trigger the NFC
service to restart and reload the setting.

It controls permissions for NFCEE administration
and is checked based on the signature of Nfc.apk
and the caller.

The NFCEE admin permission checking is currently
set to check the stock NFC permission.

The pattern matching wasn't sufficient with the
move to identifying technologies with their class
names so now we use a custom dispatching mechanism.

The home screen and other system apps call stopAppSwitches() to prevent
malicious applications from starting their activity again when the user exits.
The startActivity() call is delayed by 4 seconds.

We can override this in NFC service because we are a system service, using
resumeAppSwitches(). If a tag comes into the field we really want to show it
immediately. It feels really laggy otherwise.

- starting at app onCreate() is about 6 seconds before BOOT_COMPLETE
- enable hardware immediately, but do not send any intents until
  BOOT_COMPLETE (using mBootComplete to guard).
- add mutex's around some fields that needed it

The fields that are still not thread-safe were non-trivial to fix.

Uses ServiceManager.addService() to register the service.

Uses BOOT_COMPLETE to start the service.

Uses sharedUserId com.android.nfc so that it has a fixed uid.

Uses android:persistant so that the process is not killed.

NFC application contains the NFC service code that implements NFC API and
talks to NFC hardware.

This is the first cut at moving NFC service code out of frameworks/base into
application service. Android.mk are renamed to Android.mk.hide at this commit
because it does not work yet.
