Increase max image depth to 127
Simplify and resync hack/make/test and hack/make/dyntest output handling
Clean output and simplify hack/make/*test by adding go_test_dir function in make.sh
Add much better pruning of non-tested directories, including pruning the integration tests directory (doing more with "find" and nothing with "grep")
Unify hack/make/*test further by invoking hack/make/test directly from dyntest
Unify dyntest/test and dynbinary/binary hack bundlescripts further by cross-invocation and keeping all the logic in one place, taking advantage of LDFLAGS_STATIC that is the only bit that gets replaced for dyntest/dynbinary
Add separate "test-integration" bundlescript (and corresponding dyntest-integration bundlescript)
Engine: integer job status, improved stream API

* Jobs return an integer status instead of a string
* Status convention mimics unix process execution: 0=success, 1=generic error, 127="no such command"
* Stdout and Stderr support multiple thread-safe data receivers and ring buffer filtering
Engine: new command 'stop' gracefully stops a container.
