9881c532c8 bitbake: runqueue: Fix non setscene tasks targets being lost
If you specify both setscene and non-setscene tasks on the commandline, the
non-setscene tasks could be missed, e.g. "bitbake X:do_patch X:do_populate_sysroot"
and do_patch would fail to run.

Fix the problem in runqueue and add a testcase.

1069c36417 bitbake: runqueue: Optimise multiconfig with overlapping setscene
Currently if a multiconfig build contains different configurations which
have overlapping sstate artefacts, it will build them multiple times.
This is clearly suboptimal and not what users want/expect.

This adds code to detect this and stall all but one of the setscne tasks
so that once its built, it can be found by the other tasks.

We take care to iterate the multiconfigs in order so try and avoid
dependency loops. We also match on PN+taskname+taskhash since this is
what we know sstate in OE-Core would use. There are some tasks even within
a multiconfig which match hashes (mostly do_populate_lic tasks) but those
have a much higher chance of circular dependency so aren't work attempting
to optimise.

If a deadlock does occur the build will be slower but there is code to
unbreak such a deadlock so it hopefully doens't break anything.

Comments are injected into the test tasks so they have different task
hashes and a new test for this optimisation is added.

7484fb49a4 bitbake: tests: Add initial scenario based test for runqueue
We need some tests for runqueue, its been something which has been hard to test
for a long time. Add some dummy metadata to allow this, mirroring the OE
structure in spirit.
