This is the third batch of cleanups in this development cycle.
Major changes in v5: - Fix build errors - More cleanups
Major changes in v4: - Move static EXPORT_SYMBOL check to a script - Some refactoring
Major changes in v3:
- Generate symbol CRCs as C code, and remove CONFIG_MODULE_REL_CRCS.
Major changes in v2:
- V1 did not work with CONFIG_MODULE_REL_CRCS. I fixed this for v2.
- Reflect some review comments in v1
- Refactor the code more
- Avoid too long argument error
