repo download: add --cherry-pick option

default option uses git checkout, and thus overwrite the previous
checkouts.  this is a problem for automated builds of several
changesets in the same project for daily builds of pending submission

You can now use:
repo download [--cherry-pick|-c] project changeid/patchnumber

This will parse the manifest, cd to the corresponding project
download the changes to FETCH_HEAD and cherry-pick the result.

This is useful to automate cherry-picking of a patch
in the context of build automation, and commit gating (e.g. buildbot)
