[yocto] [layerindex-web][0/8] Several fixes for layerindex

[Robert Yang]

Hi Paul,

The "-a ACTUAL_BRANCH" is a litle different from what we had talked, now it
respects "-l" and "-b", we can use -l to specify layers or default to all,
and it requires "-b" to work, 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.

Robert Yang (8):
  layerconfparse.py: remove unused layerbranch from parse_layer()
  utils.py: remove obsolete dependencies
  update_layer.py: set layerbranch's collection before add_dependencies
  update.py: add -p to git fetch
  update.py: fix -l option
  recipeparse.py: restore cwd when the parsing is done
  update.py: update layers orderly
  update.py: update actual branch for layer and bitbake
