External contribution integration

External contribution integration

New external contributions are starting [1]. Here is the current team workflow defined.

We should:

• Review the diff and explain what's need adapting

• Accept the diff if ready [2]

• Integrate the patch using arcanist:

   cd /path/to/<repository-concerned-by-diff>
   PATCH_NAME=<patch-name>  # use the right patch name D301 for example
   CONTRIBUTOR_NAME="<contributor-name>"  # use the right contributor's full name
   arc patch $PATCH_NAME
   # this will create a local commit amend the commit message if
   # necessary (added a `Close <concerned-task> for example)
   echo $CONTRIBUTOR_NAME >> CONTRIBUTORS
   git add CONTRIBUTORS
   git commit -m 'Update contributors file'
   git checkout master
   BRANCH_TO_MERGE="arcpatch-$PATCH_NAME"
   git merge $BRANCH_TO_MERGE
   git branch -d $BRANCH_TO_MERGE
   git push

[2] We should only be able to accept it if the contributor has already signed the CLA
