Fix java.util.Random performance regression.
With the monitor change in ART, getting the identity hash code of an
object puts the hash code in the lock word. This hurts performance
if you synchronize on said object since it makes it that we always
go slow path for monitor enter and exit. Although the fix
allocates a new object in the Random constructor, it should not cause
performance problems assuming people don't excessively create new
random number generators.

Fix more FindBugs complaints (BufferedReader, File, and ObjectInputStream).
Also slightly improve the documentation of Random and SecureRandom.

Fix libcore javadoc errors.
Random's javadoc was pretty random, and Pattern was missing some escaping
in code samples.
Also work round droiddoc bugs that were messing up Formatter and classes
that inherited documentation from Object.

Gentlemen, you may now set your editors to "strip trailing whitespace"...

Fix java.util.Random's constructors.
Subclasses rely on having their overridden setSeed called by Random's
constructors, and the RI actually documents this behavior. (The
documentation even changed between Java 5 and Java 6 to make it _more_
explicit.)
This patch keeps that part of I6239d93bb46876ef1c4a5e155a6dc1ac6fab4eae
that improved our randomness, but reverts the attempt to fix Random's
uncouth behavior.
Also a regression test so we don't try to fix Random again in future.

Fix the docs for the no-arg Random() constructor to better reflect reality,
and make the constructors more resilient with respect to subclassing by
using System.identityHashCode() instead of Object.hashCode(), and also by
not calling overridable methods.

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
