The sstate cache mechanism currently has a blind spot: log messages shown
while a task first runs are not replayed when the task output comes back
from the cache. This is particularly true for warnings, which are
effectively hidden unless the task is rebuilt.

This openembedded-core series saves each task's messages into the sstate
cache and replays them when cached output is reused. Logs are also
replayed for tasks that are not themselves sstate-covered but are
dependencies of covered tasks. This requires the companion bitbake
series.
