[poky] [PATCH 00/11] [RFC] fetch overhaul - API reorg and git optimization

[Yu Ke]

Hi Richard,

This patch series is for the fetcher overhaul phase 2 - new API reorg, and part of phase 3 - git optimization. the details are:

- Split go() methods into the following steps:
  i) download() - do whatever transfer is necessary to get the sources locally
  ii) build_mirror_data() - generate any data that would be needed to construct a source mirror
  iii) unpack() - takes a directory as an argument of where to place extracted sources
- Change Poky's fetch task to call a "download" method in the fetcher instead of go().
- Change Poky's unpack to call an unpack method in the fetchers.
- Optimise git fetcher for the new layout so for a git checkout, we clone the repository in download(), then unpack just does a clone with references to the original repo.

The remaining item for phase 3 are:
- Add a new "BB_NO_NETWORK" option to only perform local fetch
- Add multiple branch/srcrev support for git fetcher
