base.bbclass: added support for creating source mirror

- if SOURCE_MIRROR_FETCH variable is set then we ignore
  COMPATIBLE_MACHINE/COMPATIBLE_HOST settings to be able to fetch all recipes.
- Fetching sources can be done by setting any MACHINE/DISTRO combination and
  SOURCE_MIRROR_FETCH = "1" in configuration. Then one invocation of BitBake
  should do all fetching:
  bitbake --cmd fetchall --continue world
- scripts to manage source mirror will get added into contrib/
