[PATCH v2 0/3] Sstate-cache follow-up

[Adriaan Schmidt <adriaan.schmidt@siemens.com>]

This adds the test case for the sstate-cache that we postponed
when merging the original sstate series.
It also includes the current draft from our discussion of changes
to the testsuite itself (rebased on next).

And some basic documentation of the sstate feature. It does not go into
any details on how to operate a deployment with (shared) caches in
practice. We're still gathering experience with that ourselves, but at some
point I hope we can provide some best-practice recommendations and
a script/utility for cache maintenance.

changes since v1:
- rebase on next
- add check to verify contents of deploy dir when using sstate caching

Adriaan Schmidt (3):
  testsuite: refactor
  sstate: add test case
  doc: add sstate to user manual
