Subject: Changed external functions to enable global installation * up until
 now all external functions were locally installed to a specific
 XalanTransformer instance contained within a TransformationGuard instance **
 this had to change as I planned to add a "execute-transformation" function
 based on TransformationGuard which would have led to recursive
 self-instantiation ** global external functions have to be thread-safe * as
 global external function can not be provided with a reference to a
 transformation-specific FilesystemFacade instance, the working path is now
 determined using xalan::Locator ** currently using pointer arithmetics on
 XMLCh* to remove the "file://" prefix of the URI returned by
 locator->getSystemId(), may be unsafe * added compilation unit for
 PlattformGuard as it now contains function installation in addition to
 plattform lifetime management
