Fix AbstractStringBuilder gaining extra APIs.
AbstractStringBuilder showed up in the API as gaining methods originally
belonging to StringBuffer/StringBuilder (mostly append(*) and
insert(*)).
Ideally it should not be in the API at all, but it's traditionally been
there and we'll keep it for now.
@hide the affected methods and move the "implements Appendable"
definition to StringBuffer/StringBuilder (as methods implementing an
interface can't be @hidden).

Avoid performing boundary checks in StringBuilder
We can improve performance by avoid performing boundary checks when the
indices are guaranteed to be within bound.

Optimize StringBuilder.append for String with range
by using String.charsAt to avoid performing 1-by-1 copying.
Also adds a benchmark testing append for substring.

Optimize StringBuffer/Builder#appendFloat/Double/Boolean
Moved FloatingDecimal from sun.misc to java.lang package,
so it can access AbstractStringBuilder class (and do
not duplicate same code for the StringBuffer and the
StringBuilder).
FloatingDecimal is no longer instantiated, but
accessed from thread local storage and reused.

Initial import of OpenJdk files.
Create new libcore/ojluni directory with src/main/java and
src/main/native subdirectiories.
Build ojluni into core-oj jar.
Use openjdk classes from java.awt.font package.
Copy all files from jdk/src/share/classes and jdk/src/solaris/classes
directories in openjdk into libcore/ojluni/src/main/java.
Copy following native files from openjdk to
