Currently siggen uses the format "<filename>.<taskname>" for referencing tasks
whilst runqueue uses "<filename>:<taskname>". This converts to use ":" as the

This is an API breaking change since the cache is affected, as are siginfo files
and any custom signature handlers such as those in OE-Core.
Ultimately this will let us clean up and the accessor functions from runqueue,
removing all the ".rsplit(".", 1)[0]" type code currently all over the place.
Once a standard is used everwhere we can update the code over time to be more

There is a compelling usecase for tasks being able to notify runqueue
that their "unihash" has changed. When this is recieved, the hashes of
all subsequent tasks should be recomputed and their new hashes checked
against existing setscene validity. Any newly available setscene tasks
should then be executed.
Making this work effectively needs several pieces. An event is added
which the cooker listen for. If a new hash becomes available it can
send an event to notify of this.
When such an event is seen, hash recomputations are made. A setscene
task can't be run until all the tasks it "covers" are stopped. The
notion of "holdoff" tasks is therefore added, these are removed from
the buildable list with the assumption that some setscene task will
run and cover them.
The workers need to be notified when taskhashes change to update their
own internal siggen data stores. A new worker command is added to do this
which will affect all newly spawned worker processes from that worker.
An example workflow which tests this code is:
Configuration:
BB_SIGNATURE_HANDLER = "OEEquivHash"
SSTATE_HASHEQUIV_SERVER = "http://localhost:8686"
$ bitbake-hashserv &
$ bitbake automake-native
$ bitbake autoconf-native automake-native -c clean
$ bitbake m4-native -c install -f
$ bitbake automake-native
with the test being whether automake-native is installed from sstate.

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.

This is the serious functionality change in this runqueue patch series of
changes.
Rather than two phases of execution, the scenequeue setscene phase, followed
by normal task exeuction, this change allows them to execute in parallel
together.
To do this we need to handle marking of tasks as covered/uncovered in a piecemeal
fashion on a task by task basis rather than in a single function.
The code will block normal task exeuction until any setcene task which could
cover that task is executed and its status is known. There is a slight
optimisation which could be possible here at the risk of races but that
doesn't seem worthwhile.
The state engine isn't entirely cleaned up in this commit (see FIXME) and
the setscenewhitelist functionality is broken by it (see following patches)
however its good enough to test with normal workflows.
