Fix OPENDJ-70 : Build does not create the proper reference schema in the config/upgrade directory ldapSyntaxes were not copied over.

Updated the copyright statement to reflect that Sun owns the full copyright on the project files.

Make several significant changes to the OpenDS code base, including: - Narrow down the set of packages that external developers will need to access in order to write a plugin or other type of extension. Hopefully, for most things developers will only need to interact with the following packages (and their sub-packages): * org.opends.server.admin * org.opends.server.api * org.opends.server.config * org.opends.server.protocols.internal * org.opends.server.types * org.opends.server.util - As part of the attempted narrowing of packages that external developers need to access, I have moved the org.opends.server.core.Operation and org.opends.server.protocols.ldap.LDAPException classes to the org.opends.server.types package. I have also created org.opends.server.types.RawAttribute to wrap the org.opends.server.protocols.ldap.LDAPAttribute class, and org.opends.server.types.RawModification to wrap the org.opends.server.protocols.ldap.LDAPModification class. - I have updated the internal operations API to add a few new convenience methods when performing internal operations. - I have updated all of our message strings so that none of them end in periods (except those that end with an ellipsis). This will help us avoid the problem in which we see multiple periods due to embedding one message in another. - I have moved a message file from a synchronizaiton package to the messages package and resolved conflicts with existing message IDs. - I have updated a number of cases in which StaticUtils.stackTraceToSingleLineString() was used in client-facing code to replace those calls with StaticUtils.getExceptionMessage() instead. This should provide a more user-friendly message that will hopefully not reduce our ability to debug problems that may arise. - I have cleaned up some of the code in the org.opends.server.api package so that all of the classes use consistent formatting, and to fix a couple of potential Javadoc problems. - I have moved the build-tools/src directory to src/build-tools to be more consistent with other components of the server. - I have updated the build script so that the xslt task will no longer dump lots of output to the terminal when generating code. I have also gotten rid of warnings about run.classpath not being set properly.
