disk layer gc and error/warnings cleanup (#515)

- Improvement: Use GC reserve when writing index/manifest for a disk cache bucket when disk is low when available
- Improvement: Demote errors to warning for issues that are not critical and we handle gracefully
- Improvement: Treat more out of memory errors from windows as Out Of Memory errors

Fixed wrong sizeof() statement for compactcas index (luckily the two structs are of same size)
