Rmk161 loadup works with utf 8 source files (#2512)

* New starter.sysout contains the UTF-8 external format
* Init.sysout is created with the UTF-8 external format
* Files with non-ascii characters and some other files converted to UTF-8, for basic testing
* Environment arg of WITH-READER-ENVIRONMENT can be a stream
* Compiler functions now respect the external format as copied from the source file
* Colon is the package delimiter in DEFINE-FILE-INFO expressions
* UNICODE file is deprecated in favor of UNICODE-FORMATS and UNICODE-TABLES
