The specification of the Java deserialization demands that a private
readObject(ObjectOutputStream) method is used -- if it exists. In
that case, ObjectInputStream must not initialize the contents of the
fields (called 'classdata[]' in the documentation) but offer that
functionality via the defaultReadObject() method.

The serialization protocol specifies a quick method to serialize
a String (because that is so common an operation): TC_STRING +
(short)length + bytes. Let's use that, also to make it easier to test
the upcoming changes to TreeMap harmonizing that Avian's serialization
of said class with OpenJDK's.

This is by no means a complete support for the deserialization compliant
to the Java Language Specification, but it is better to add the support
incrementally, for better readability of the commits.

The Java Language Specification documents the serialization protocol
implemented by this change set:
http://docs.oracle.com/javase/7/docs/platform/serialization/spec/protocol.html#10258
This change is intended to make it easier to use Avian VM as a drop-in
replacement for the Oracle JVM when serializing objects.
The previous serialization code is still available as
avian.LegacyObjectInputStream.
This commit only implements the non-object parts of the deserialization
specification.

This implementation is intentionally simple. If and when the need arises,
we can always implement a more performant version.

If need be, this functionality can be sped up by implementing a
descending iterator on the tree without copying it into an ArrayList.

This change reuses the existing insertion sort (which was previously what
Arrays.sort() executed) in a full intro sort pipeline.
The implementation is based on the Musser paper on intro sort (Musser,
David R. "Introspective sorting and selection algorithms." Softw., Pract.
Exper. 27.8 (1997): 983-993.) and Wikipedia's current description of the
heap sort: http://en.wikipedia.org/wiki/Heapsort.

This is a very dumb implementation that wastes space and time by
constructing a full-blown ArrayList as backend. However, it is
better to have a dumb implementation than none at all, and we can
always do something about the performance when, and if, that should
become necessary.

In the previous commit, we did not support characters in regular
expressions specified via \0..., \x... or \u... yet. This is a bit more
involved, therefore support for them is added in its own commit.

When a regular expression contains escaped characters such as the
backslash, it is actually still a literal string. So let's support the
trivially-escaped characters, too, that are documented in
http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

This implements all the methods required by the DataOutput interface; to
run Bio-Formats' bfconvert tool, actually only the write() and writeByte()
methods would be required.
