Subject: A more convoluted #pragma once file identity test, using relative
 paths. (#1021)

* A more convoluted #pragma once file identity test, using relative paths.

* Fix bug with passing - to slang as a command line option causes a crash.
Ability to set file-system to use on command line.
#pragma once tests try with 'normal' and 'read-file' only versions

* OSFileSystem -> OSFileSystemExt
LoadFileOSFileSystem -> OSFileSystem

Implemented OSFileSystem like OSFileSystemExt as as singleton.
Fixes to comments.
