Make it easier to build the database client libraries:

 1) Add Makefile.download-db-libs, which downloads + unpacks all of the dependencies.
 2) Fix build.xml so that downloaded libraries don't break ant doc
 3) Add dbcompile-all target that builds all of the client libraries at once.

Makefile.download-db-libs

+#
+# Running 'make -f Makefile.download-db-libs' will automatically download all 
+# of the libraries needed to build the YCSB drivers.
