[PATCH 0/4][layerindex-web] bug fix and performance improve

[Robert Yang <liezhi.yang@windriver.com>]

Hi Paul,

The patch 4 can improve a lot on update.py (up to 98%), here is the testing
data, please feel free to give your comments.

$ time update.py -b master --nofetch [--fullreload]

                   Before    Now       Reduced
No update:         276s      3.6s      98%
Partial update:    312s      87s       72%
Full repload:      1016s     980s      3%

Note:
* All of the testing are based on --nofetch

* "No update" means all layers on the branch is up-to-date, for
  example, when we run it twice, there is no update in the second run, so we
  only need about 3s now, which is the most common case when we use cron to run
  it per half an hour.

* "Partly update" means part of the layers have been updated.

* "Fullreload" means all of the layers have been updated.
