Provide mini-os url and revision in Config.mk
Make stubdom targets depend on mini-os-dir target. Make
subtree-force-update{,-all} depend on mini-os-dir-force-update.
Also make mktarball script generate mini-os archive.
Original mini-os directory is renamed to mini-os-intree to help reduce
patch length. That directory will be deleted in a separate patch.

Changes in v3:
1. Put mini-os targets in main Makefile.
2. Stubdom clean and distclean don't depend on mini-os-dir.
Changes in v2:
1. Use hash in Config.mk.

# of which would indicate an "unrecognized command-line option" warning/error.
