https://github.com/shijunjing/edk2/tree/build_cache_improve_v6_3

V6:
In the patch 5, add error handling to skip hash calculation if find module cache already crashed

V5:
Fix the method name typo in Misc.py from EdkLogger.quite() to EdkLogger.quiet()

V4:
Change single global lock into two locks, which are cache_lock and file_lock, for better cache performance and IO reliability in windows

V3:
Add patch 5. To improve the autogen CopyFileOnChange() and SaveFileOnChange() functions reliability for build cache

V2:
Enhance the SaveHashChainFileToCache() function in ModuleAutoGen.py and not need to call f.close() in the "with open(xxx) as f:" block. The with block will close the file automatically

V1:
Initial patch set
