Also globally replace "for(" with "for (".

Use int.class instead of Integer.TYPE (et cetera) for clarity.
I've also removed some small amount of duplication and a few unused imports.

Better tests for Float.parseFloat/Double.parseDouble, plus some fixes.
I'm not happy with the magic 1024s, and I had hoped to have one hack to
cover both harmony bugs. But this passes all our existing tests, all
harmony's existing tests, and the new tests I wrote while looking at
the code. (The new tests all pass on the RI too.)
I've also made a few doc comments slightly less unclear.

Fix Float.parseFloat (et cetera) javadoc.
None of these constructors or decode/parse.*/valueOf methods throw
NumberFormatException when passed null, so they shouldn't claim to do so.

Move Integer and Long's toString methods into a new class.
I've reverted the old optimizations that used shifting and addition instead
of multiplication, because that's been slower for a while now. I've also
switched to more consistently using DIGITS. Otherwise, this code is unchanged.
I've also changed Float.toHexString to use StringBuilder.append(int) instead
of calling Integer.toString manually (with an eye to taking advantage of future
more efficient implementations of StringBuilder.append(int)).

Speed up Float.toString (and Double.toString).
The special cases (NaN, infinities, and zeros) go from 30us to 1us.
There are basically three other paths through the code, depending on the value:
The small case goes from 60us to 30us.
The medium case goes from 70us to 31us.
The large case goes from 100us to 50us.
There's way less garbage produced, and now we're using StringBuilder, we're
in a position to take advantage of future optimization of
StringBuilder.append(int).

Minor tidy-up of Float.toString and Double.toString.
This patch looks larger than it is. I've moved duplicated constants out of
Math and StrictMath and into Float and Double where they belong. I've also
moved a table out of BigDecimal so I can reuse it in NumberConverter, which
I've renamed to RealToString.
The main active ingredient here is that there's no longer StringBuilder usage
to prepend '-'. This actually brings us down from 74ns to 62ns for an easy
case like 123.45f.

Remove @hide from Java 6 API.
I've left the two new spi packages @hidden, because I think we shouldn't
support them without convincing demand from developers (and I don't
believe there could be such a thing --- they just don't make sense, and
if we add anything, it should be the ability to provide extra ICU data).
Also fix a handful of javadoc syntax errors in Arrays.java and TreeMap.java.

Remove //$NON-NLS-\d$ cruft.
Mostly done by perl(1), with manual cleanup of the few misspelled instances.
This makes our trailing whitespace slightly worse, but I'll fix all that with
a follow-on change.

Add Java 6 additions to Double, Enum, Float, and String.
I rewrote the documentation for Double, Enum, and Float, but the "code" is the
same as harmony's. I rewrote the String code and wrote some tests to ensure
that a malicious Charset can't subvert String immutability.
I've also extracted the Android-specific bits of StringTest (which weren't
testing String at all) and brought back the latest harmony StringTest.java.
(The Class and Package changes are just to placate our API comparison tools.)

Based on user-submitted bugs that were just misunderstandings, plus
implementation bugs caused by the intended behavior being somewhat
subtle.

Rewrote all the toString and bit twiddling code in Integer and Long using
state-of-the-art recipes. The resulting code is much faster than what it
replaced, as well as being more concise. While I was in the neighborhood
I also cleaned up a few other things in the boxed primitives (TYPE fields,
small-value caches, etc.).
Addressed review comments.

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
