[OE-core] [PATCH V2 0/3] bbclass/sstate: only allowed sstate-cache objects are allowed in a build (read-only sstate-cache)

Changed in V2:
- add hook SSTATE_CHECK_FUNCTIONS for sstate checking, and
add a new bbclass/sstate_readonly, rather than directly
modify bbclass/sstate
- terminate build safely while RunQueueExecuteScenequeue
init failed, the previous bb.msg.fatal is too hack.
Test steps:
1) vim local.conf
INHERIT += 'sstate_readonly'
2) Create a sstate cache for testing
$ bitbake db-native
3) Remove tmp dir and build db-native from sstate-cache
$ mv tmp tmp-back && bitbake db-native
4) Add gzip to SSTATECACHE_WHITELIST, it enabled read-only sstate-cache,
vim local.conf
...
SSTATECACHE_WHITELIST = 'gzip'
...
5) Remove tmp dir and build db-native from sstate-cache
$ mv tmp tmp-back && bitbake db-native
6) tweak db's do_configure task by adding comments
