[poky] [PATCH 3/7] bb: add bb.fetcher as dynamic fetch module instance for fetch/fetch2

[Yu Ke]

bb.fetcher is introduced to swtich between bb.fetch and bb.fetch2.
all bb.fetch/bb.fetch2 referrence can be replaced with bb.fetcher.instance,
so that we can cleanly switch between bb.fetch and bb.fetch2
