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

In particular when constructing regular expressions before compiling them,
it is a good idea to state which exact expression is non-trivial when
complaining about it.

Previously, I used a shell script to extract modification date ranges
from the Git history, but that was complicated and unreliable, so now
every file just gets the same year range in its copyright header. If
someone needs to know when a specific file was modified and by whom,
they can look at the Git history themselves; no need to include it
redundantly in the header.
Added to collection:
public boolean containsAll(Collection<?> c);
public boolean removeAll(Collection<?> c);
Added to list:
public boolean addAll(int startIndex, Collection<? extends T> c);
Also where possible for inner classes I made them extend the abstract version instead of just implement the interface. This helps reduce code duplication where possible.
These changes were necessary to support protobuf 2.5.0
The ArrayList(Collection) constructor was allocating two arrays
instead of one due to an off-by-one error in ArrayList.grow. This
commit fixes that and makes grow and shrink more robust.
The previous code caused frequent seed collisions for successive calls
to the no-arg constructor, even for single threaded workloads. This
patch should avoid such collisions in both single and multi-threaded
cases.
