Add the dump_cache.py to dump the "recipe -> packages" mapping for
target recipes form bb_cache.dat:
* Usage:
dump_cache.py bb_cache.dat
* The format is:
recipe_path pn pv packages
For example:
/path/to/gzip_1.5.bb gzip 1.5 gzip-dbg gzip-staticdev gzip-dev gzip-doc gzip-locale gzip
* Only save the mapping for the target recipe
* We can extend this to dump other informations when needed.
* Put this script to bitbake/contrib/ (not to oe-core) is because it
needs the bb.cache.
