Speed up the way we access ICU's locale data.
This patch makes creating a new NumberFormat or new SimpleDateFormat 2x faster.
Basically, the ResourceBundle mechanism is really expensive in several ways:
1. The two-level caching is unnecessary for locale data, and expensive because
it burns through a lot of temporary objects.
2. The PrivilegedAction stuff is unnecessary and expensive because it too burns
quite a few temporary objects (including an ArrayList for each call; should
we consider removing support for SecurityManager so we can remove this cruft
from our code?).
3. The caching in most cases doesn't cache anything useful; the ResourceBundles
simply forward all questions straight to native code anyway, all we're
caching is an unnecessary forwarding object (in a cache where lookups cost
more than just creating a new unnecessary forwarding object would cost).
I've left CurrencyResourceBundle on the slow (ResourceBundle.getBundle) path
because I'm not yet sure how much of that path's semantics it relies on.
I still return LocaleResourceBundle instances (albeit via a much faster path)
but we should fix that. The native code returns an array which ResourceBundle
stuffs into a Hashtable and the calling code accesses via hash table lookups.
This despite the fact that the keys are a small fixed set known in advance.
We could make the native layer and the calling layer simpler and faster by
using a "struct", and doing so would make the middle layer go away completely.

Udating luni to Harmony r823222.
Highlights:
- InputStream.skip concurrency issue
- "better" messages in bound exceptions for streams and arrays
- prefer fewer writes to underlying streams (using byte[] buffers)
- Rename subclasses to not reuse names from their superclasses
- PlatformAddressFactory.allocMap bugfix
Plus some spelling fixes, style fixes, serial version UIDs and other
boilerplate improvements.

Update Luni to Harmony r802921.
Notable changes:
- replaced StringBuffer with StringBuilder in several places
- fixed a problem with BufferedInputStream's newline characters (EBCDIC)
- cleanup Timer's finalizer helper object
- new cache for the canonical path of a file
- fixed concurrency issue with ArrayList
- floating point parsing now trims length for very small numbers
- encoding specified "UTF-8" when converting some byte[]s to strings (JarURLConnection, Util, OSFileSystem)
- Harmony now implements floor and ceil in Java. We continue to use native code.

Integrate luni module (but not tests) to Harmony r772995.
Notable changes
- Stripped "@since Android 1.0" from many files. Most files
are now 100% the same in Dalvik and Harmony.
- AbstractStringBuilder.reverse() supports surrogates
- AbstractStringBuilder shares less to waste less memory
- Bitset optimized
- BufferedInputStream changed to support unsynchronized close()
- BufferedOutputStream does flushInternal
- BufferedReader supports EBCDIC NEL
- Collections.synchronizedList().indexOf() does a copy for more concurrency
- Classes in nio module changed: DatagramChannelImpl, SocketChannelImpl
and ServerSocketChannelImpl (these depend on internal APIs changed in
this update)
- DataInputStream/DataOutputStream now use a small buffer to limit the
number of times the underlying stream is accessed
- Date now has a minutes offset, more efficient toString()
- ExposedByteArrayInputStream: new internal class
- DeleteOnExit moved to top-level class
- FileDescriptor.isValid() now non-native
- Float, Double lessThan optimized (fix for compare(-0.0F, 0.0F) still pending)
- FileURLConnection now guesses content types from streams
- HashMap iterator changes
- Hashtable iterator changes
- INetworkSystem
- removes bind2(), createMulticastSocket, sendStream(),
- renames createSocket to createStreamSocket
- JarURLConnection rewritten
- LinkedHashMap: new iterator
- Locale, Currency, TimeZone: now use ICU in Harmony, plain Java in Dalvik
- ObjectInputStream: Accessor objects in Harmony, direct native in Dalvik
- ProxyClassFile - many changes
- String - optimized ascii for toLowerCase, toUpperCase, compare
- Timer - rewritten
- TreeMap - rewritten
- URLClassLoader - new
- URLConnection - new guessContentTypeFromStream(), uses org.apache.harmony.awt.www.content
to lookup content type handlers
