On the javahl-diff-summarize branch: Work-in-progress bindings for
svn_client_diff_summarize().  Development on the bindings is basically
done, but there's a bug hiding somewhere which is throwing an
exception (in native code, I believe), and subsequently causing a
segfault when the JNI ExceptionDescribe() API is invoked by JavaHL's
exception handling code.

[ in subversion/bindings/java/javahl/ ]

* native/SVNClient.h
  Forward declare the DiffSummaryReceiver class.
  (diffSummarize): Declare new method.

* native/SVNClient.cpp
  Add include of DiffSummarReceiver.h.
  (SVNClient::diffSummarize): Add new method which invokes
   svn_client_diff_summarize().

* native/DiffSummaryReceiver.h
* native/DiffSummaryReceiver.cpp
  Add DiffSummaryReceiver class.

* native/org_tigris_subversion_javahl_SVNClient.cpp
  Include DiffSummaryReceiver.h.
  (Java_org_tigris_subversion_javahl_SVNClient_diffSummarize): Add JNI
   binding.

* src/org/tigris/subversion/javahl/SVNClientInterface.java
* src/org/tigris/subversion/javahl/SVNClient.java
* src/org/tigris/subversion/javahl/SVNClientSynchronized.java
  (diffSummarize): Add new API

* src/org/tigris/subversion/javahl/DiffSummaryReceiver.java
  A new Subversion diff summarization interface.

* src/org/tigris/subversion/javahl/DiffSummary.java
  A new data object for use with the DiffSummaryReceiver interface.

* src/org/tigris/subversion/javahl/tests/BasicTests.java
  Import java.util.ArrayList.
  (testDiffSummarize): New test for SVNClientInterface.diffSummarize(),
   which performs a recursive diff summary, ignoring ancestry.  This
   test is currently failing, causing a JVM segfault.
  (DiffSummaries): Basic implementation of the DiffSummaryReceiver
   interface, for testDiffSummarize().
