misc: Tweak Android change documentation, revert redundant changes.
Tweaked existing or added missing Android change documentation
for misc ojluni .java files.
Also got rid of a couple of small needless differences
(e.g. indentation) vs. upstream OpenJDK8u121-b13.
The selection of files touched by this CL is fairly arbitrary.
Future CLs will likely apply similar changes to other files.
AbstractStringBuilder: Revert minor indentation difference vs. upstream
ArrayIndexOutOfBoundsException: Tweak docs for @hide constructors
Byte: Tweak change docs
Console: Minor tweaks to minimize diff, minor improvements to change docs
DeleteOnExitHook: add missing Android-changed documentation
InterruptedIOException: Added change comment body.
HijrahChronology: Revert minor indentation difference vs. upstream
SocketTimeoutException: Added change comment body.
Serializable:: add missing Android-added documentation.
SerializablePermission: Improve toplevel documentation, added Android-changed comment
Bug: 35910877
Test: Treehugger build succeeds

user: igerasim
date: Fri Mar 04 14:03:34 2016 +0300
summary: 8149330: Capacity of StringBuilder should not get close to Integer.MAX_VALUE unless necessary
Adding tests for this change is not possible due to memory constraints.

Port openJdk8 java.lang package, part 2
- Removed floating to/from string performance hacks
we have added on the top of openJdk7 code (no longer needed)
- AbstractStringBuilder is Appendable again, we may decide
to revert this (see b/27582395 for context)
- New String method #join

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).
Bug: 27582395

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 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.
