[PATCH v2 0/8] add more ref consistency checks

[shejialuo <shejialuo@gmail.com>]

Hi All:

This version handles the following things:

1. Remove code which checks the object where refs point to suggested by
   Patrick.
2. Use subshell for the shell script to fix the problem to make sure the
   current working directory consistent.
3. Optimize to avoid allocating too much memory.

This version is rebased to the latest master due to semantic conflict. I
don't provide range-diff here the mumber of commit is reduced. However,
it won't bring too much burdern for the reviewer due to small change.

Thanks,
Jialuo
