os2: added OS/2 support back in.
With the release of ArcaOS, this is a live platform again. This code probably doesn't compile yet; I've just given it a first shot at resolving the changes between the last OS/2-supported revision and now. This still needs Unicode support added in any case.

|

- Reduce the BAIL and GOTO macro use. A lot of these don't add anything.
|

- Modernize CMakeLists.txt
|

- Change the term "search path" to something less confusing.
|

- OS/2 codepages. No full Unicode in the filesystem, but we can probably make

a conversion effort.

Probably other stuff. Requests and recommendations are welcome.
