manage local patches

We could not put the source code of ceph or other projects due to
different license, and so we have to only manage those changes locally.
This patch provides one way to apply local patches into source code
from public repo.

We can use the '.rc' file in every project to configure the branch, repo
and list all local patches which need to be applies into original branch.
And then use 'do_patch.sh' script to apply them one by one, e.g.
  $ src/do_patch.sh src/ceph/ceph.rc
