make it easy to use by recipe maintainer

* Usages: (No settings is required by default)
- Upgrade one recipe:

    $ upgradehelper.py less

- Upgrade multiple recipes:

    $ upgradehelper.py less bash

The commit will be kept in the repo when *succeed*. No commit when *failed* by default unless -f is used.

- Upgrade recipes and apply failed patches after the upgrade is done:

    $ upgradehelper.py less bash -f

- Upgrade all recipes and send emails:

    $ upgradehelper.py all -e

* Next:
- Auto fix do_fetch error when thera are more than one checksums, e.g., git repo.
- Add it into oe-core and suggest maintainer uses it ?
