Use OpenJdk implementation of java.lang.* [part 1]
- Changes to String hashing.
- Change StringCoding.isTrusted.
- For boxed primitive types, change how TYPE is derived (use the
array equivalents component type).
- System: the security manager is now always null. Also, port over
changes to make system properties read only.
- StrictMath : Use our existing fdlibm and remove references to
jdflibm.h.

Use -fvisibility and clean up a little.
The visibility change isn't obviously useful, but it's a good excuse to clean
up some of our networking code a little.

Remove dynamic calls to FindClass.
Initially, I was just fixing a threading bug in NativeDecimalFormat.cpp where
we were bypassing GCC's built-in static initializer thread safety. This led me
to the question of how expensive FindClass is, which led me to creating a new
canonical cache of jclasses.
Here's the motivating benchmark, showing the cost of calling an empty regular
(non-native) method, an empty native method, a native method that calls
FindClass, a native method that calls FindClass and GetFieldID, and a native
method that calls FindClass and GetMethodID:
benchmark ns logarithmic runtime
NoArgsRegular 74 ||||||||||||||
NoArgsNative 428 XX|||||||||||||||||||
FindClass 3064 XXXXXXXXXXXXXXXX|||||||||||
FindClassGetField 3654 XXXXXXXXXXXXXXXXXXX|||||||||
FindClassGetMethod 5634 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Use Integer.valueOf rather than "new Integer" (et cetera) from JNI.
Also factor it out rather than keep duplicating it.
