+* Generic thread safe server starter used to start server

+* WINS environment requirements:
+* - target must be normal polymorphic dll
+* - 1st exported function must be castable to TThreadFunction
+* - Thread function parameter is TPEngServerParams*.
+*
+*
+* THUMB environment requirements:
+* - target must be normal executable, epocexe
+* - if started using this launcher, RProcess command line
+*   is TPEngServerParams contents. If exe is started by other
+*   means, e.g. with file browser, then no TPEngServerParams contents
+*   available in RProcess command line.
