5e38c1c8fe examples: Remove old hcl examples 
The hcl frontend was removed a while back. Might as well remove these
examples too.

ae7ebeedd1 engine: resources: Add CheckApply event detection to resource tests 
This adds the ability to wait with a timeout for CheckApply happenings
in a resource. This helps avoid unnecessary long sleeping and timing
guesses. This also adds a cleanup function to run at the end.

652b657809 resources: exec: Avoid possible deadlock race 
Some of the early code I wrote probably wouldn't pass my own reviews
today. Here's one example of a rare deadlock that could sometimes occur
when a Process/CheckApply caused a shutdown, but the bufio tried to send
on a channel that nobody was going to read any more. Now we properly
unblock that send with a context.

aa165b5e17 engine: Add the retry loop around Process 
This adds back the retry loop around Process. This is done as a
separate commit so you can more easily see the logic of the retry magic
This commit is similar but different to the earlier commit adding retry
around Watch.

253ed78cc6 engine: Rewrite the core algorithm 
The engine core had some unfortunate bugs that were the result of some
early design errors when I wasn't as familiar with channels. I've
finally rewritten most of the bad parts, and I think it's much more
logical and stable now.

This also simplifies the resource API, since more of the work is done
completely in the engine, and hidden from view.

Lastly, this adds a few new metaparameters and associated code.

There are still some open problems left to solve, but hopefully this
brings us one step closer.

4860d833c7 converger: Rewrite the converger module 
I found a deadlock in the converger code, and I realized the code was
sufficiently bad that it needed a good clean up.

b1f088e5fa engine: resources: Add a test running for testing individual resources 
This adds a simulated engine that can run and test single resources. It
can't test all aspects and features that the engine supports, but is
probably pretty decent for testing the actual CheckApply and Watch
semantics. Be warned that it actually applies changes on your machine,
so please don't write tests that make undesirable changes.

f368f75209 lang: funcs: core: Drop unnecessary core prefix from imports 
This unbreaks the mcl bindata code. Of course we could change the parser
to allow this prefix, but this is cleaner. The packages still have a
core prefix, which it seems we could also remove, but this isn't
particularly important for anything.
