Symbol versioning

I've started to add symbol versioning to heimdal libraries to avoid exporting symbols all over the place.

 This have some bad side effekts. As usual there is not just one format for the file. The gnu ld one is what I currently support, so I have to munch the gnu file and produce a flat-file too (for Mac OS X).

 The other that is causing more problems is that its no longer possible to unit test internal functions, because libraries that no longer export those symbols. Right now I have no real solution to the problem. One is to build a library without symbol versoning and test with that. Other is to just build that module, but that doesn't work with libtool since libtool requires object files to be of the same type. Ie a object can't belong to a binary and a library at the same time. Beloning to to  two library or two binaries are fine though. But building two files doesn't really appeal to me, I'm waiting long enough as it is already. Currently I just export the function and hope that consumers wont use them.

  3. Symbol versioning represents a crucial advancement in the field of software development, offering a robust mechanism for managing and evolving libraries and their APIs over time. By assigning unique version identifiers to symbols within libraries, symbol versioning enables developers to introduce changes and enhancements without disrupting compatibility with existing applications. This granular approach to version control ensures that applications can seamlessly transition to newer library versions while maintaining backward compatibility with older versions. Symbol versioning thus promotes software stability, facilitates efficient dependency management, and fosters a more agile and resilient software ecosystem. Its widespread adoption underscores its significance in enabling the evolution of complex software systems while minimizing the risk of compatibility issues.
