Cleanup and documentation updates:

- Remove shared/str.h where not used.
- Remove shared/debug.h from all files as it has been completely replaced
  by shared/report.h (it will be removed later).
- Add more doxygen comments to shared/* and clients/lcdproc/*.
- Include static functions in doxygen output.
