[PATCH] JavaHL: Factor out common context to be shared between SVNClient and SVNRa classes

Greetings,

This patch signifies a point post which I can merge the existing logic on
the
javahl-ra branch with starting parts of my proposed enhancements. So I hope
people still have some patience left to review them.

This patch moves parts of client context that are shared with ra context
into
common classes. As I cannot get svn to generate patches that deal with
copies
of existing file, before applying below the following svn copy command have
to
be issued:

svn cp
subversion/bindings/javahl/src/org/apache/subversion/javahl/SVNClient.java
subversion/bindings/javahl/src/org/apache/subversion/javahl/CommonContext.java
svn cp subversion/bindings/javahl/native/ClientContext.h
subversion/bindings/javahl/native/CommonContext.h
svn cp subversion/bindings/javahl/native/ClientContext.cpp
subversion/bindings/javahl/native/CommonContext.cpp

Also please note that java part of this patch is already applied in
r1343452 & r1347345
on javahl-ra branch, due to my earlier mistake.

Thank you for your help,

Vladimir
