Add an option "-a" to update actual branch for layer and bitbake, it is useful when there are many layers and need update actual branches frequently. We only can update them via website without this patch, which is not fun and easy to make mistakes. * It works with "-l", and "-l bitbake" means update bitbake branch. * It requires "-b" to work, and only one branch is supported in a run. For example: $ update.py -b master -a branch_20170526 All the layers which have branch master and actual_branch branch_20170526 will be updated to branch_20170526. $ update.py -b master -l meta-oe -a branch_20170526 Only meta-oe layer will be updated. $ update.py -b master -l bitbake -a branch_20170526 The bitbake's bitbake_branch will be updated.
