Make "user.home" changeable.
For backward compatibility. This property has always been
empty on android (and is documented as such).
This also includes a fix to treat setProperties(null) properly
to keep the test runners happy.

Improve the load/loadLibrary documentation.
Also improve the exception detail message for the default case.
Experience with third-party app developers is that the current documentation
is unhelpful and the current exception detail message is misleading. If we
didn't have to use the existing ClassLoader API, we could actually list the
exact pathnames we'd tried.

DO NOT MERGE Make system properties read only.
The issue is that some parts of the system libraries
(and the runtime) assume that these properties are
immutable. This change enforces that notion and makes
behaviour a lot more predictable.
This is not a backwards compatible change, but based
on analysis of code available to me I couldn't find any
instances where this change would break any application.
Has the side effect of fixing..

Avoid running Runtime.gc() until we need to run finalization.
This prevents excessive explicit GC which are called from apps to get
good GC behavior on Dalvik. Calling System.gc() does not help on ART
since GC for alloc is much rarer.
If running finalizers is requested following a System.gc we remember
that a GC was requested and perform it ahead of finalization.

A char array copy optimization (libcore).

- This change only handles arraycopy calls in the core libraries and
char arrays with the rest future work.

Simplify defaulting for system properties, and trust the environment less.
The originally-reported bug (https://android-review.googlesource.com/58258)
was that dalvik would fail to start if LD_LIBRARY_PATH was unset.
This changes things so we no longer have multiple default values for
java.library.path, cope better with that not being set, and don't set
it if LD_LIBRARY_PATH isn't set.

Expose LOGE and friends for use from Java. This is handy because it lets me use
printf debugging even when I've broken String or CharsetEncoder or something
equally critical. It also lets us remove internal use of java.util.logging,
which is slow and ugly.

UnsupportedOperationException rather than just logging one and otherwise
doing nothing.

Retire SecurityManager.
This change removes all the code that was calling getSecurityManager, and
removes all use of AccessController.doPrivileged. It also changes the
implementation of AccessController so it doesn't actually do anything; it's
only there for source-level compatibility.

Apply various Intellij quick fixes to java.lang.
There's one real bug here: our Integer.toString was supposed to have a cache
for small negative values, but an accidentally-introduced temporary meant we
were never using the cached values. Other than that, this is just cleanup.

Reduce duplication of tests in org.apache.harmony.luni.tests.java.lang.
These classes contained tests duplicated in Harmony and libcore. I've
removed the duplicate tests and moved the libcore originals into the
libcore/ test directory.
Also fixing System.getEnv() to return a map that implements equals()
and hashCode(). This was breaking Harmony's ProcessBuilder test.

Improved System.getProperty documentation.
We were claiming to support properties we don't (and aren't required to), but
missing many that we do (and are required to).

Use 'dst' (or an even more appropriate name where possible) rather than 'dest'.
(The ArrayIndexOutOfBoundsException for System.arraycopy already talks
about 'dst' and 'dstPos'.)

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.

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