This is to workaround an issue where SDP records will fail to register using
sdptool. When we run SystemService.start() it forks sdptool, so if we do this
four times in a row these forked processes can run in parallel, and one or
more of them fails. There is probably some thready safety issue in sdptool
or Bluez that makes it unsafe to run sdptool in parallel.
As a workaround, delay 500ms between each run of sdptool to register SDP
records when starting Bluetooth.
Before this fix it was easy to reproduce problems with service record
registration. If you turn BT off/on multiple times you can see that sometimes
one or more service records are missing. Repro rate is about 20% in my tests.
Result is that remote devices cannot connect to the missing service.
After this fix I am unable to reproduce any missing SDP records, after 30+
cycles of BT on/off. Motorola BT team also ran stress tests overnight with this
fix and were unable to reproduce the missing SDP records.
This is a low risk fix. It does delay some records from being registered
by an additional 1.5 seconds (on top of the 3 second delay we already had),
so if you try and very quickly connect a BT service after turning BT on it
won't work the first time.
Do not merge. (I will use a less hacky fix for MR2/Master)

Make functions that are meant to be BLUETOOTH_ADMIN really
BLUETOOTH_ADMIN.
Add some missing javadoc for permissions.
The only functional change here is the BLUETOOTH->BLUETOOTH_ADMIN
changes. This is super safe because every system app that uses BT
has both permissions.

Use ConnectivityManager.CONNECTIVITY_ACTION broadcast in LocationManagerService
to notify GPS when SUPL connection is ready instead of TelephonyIntents.ACTION_ANY_DATA_CONNECTION_STATE_CHANGED,
which is not sent in all cases.
Expand LocationProvider.updateNetworkState() to include NetworkInfo object.

Added a workarouond to request the A2DP output standby directly to audio hardware when the sink is suspended as it seems that the suspend request often fails.
Also take into account resume requests received while a suspend request is pending.
Sometimes during OPP, we can get stuck in Pairing state when the remote
end, cancels the Pairing process - we will just get onAgentCancel
and thus not set the Pairing state properly.

There was another way we could ignore the application windows flags
while the lock screen was displayed. This is the infrastructure to
deal with that.

This is the main entry point to the Bluetooth APIs, and returns the default
local Bluetooth adapter.
It replaces context.getSystemService(Context.BLUETOOTH_SERVICE). This was
never in a public SDK release.

Hide createRfcommSocket(int channel)
Add createRfcommSocketWithServiceRecord(UUID uuid)
Rename listenUsingRfcomm(String,UUID) -> listenUsingRfcommWithServiceRecord(..)
Now we have a complete API for developers to make peer-peer RFCOMM connections
with hard-coding the limited (30) RFCOMM channels, instead using SDP lookup
of an UUID.
This commit addresses two serious bugs:
- Do not throw IOException on accepting an incoming RFCOMM connection with
BluetoothSocket. This was a regression from commit 24bb9b8af4ff6915
- Workaround failure of bluez to update SDP cache when channel changes by
trying to use the same RFCOMM channel on the server every time, instead
of picking server channels randomly. This is a pretty ugly workaround,
and we are still trying to fix the caching issue - but with this
workaround we are at least shippable and apps will work at least until
they start colliding on the 30 RFCOMM channels.

Don't hold a lock when the activity thread is telling the activity manager
to release a provider.
This requires that the activity manager now keep a reference count on the
providers, because without the lock it is possible for activity thread to
call in to request the provider again before it has finished telling
about the release.
