Version 1.0.0

https://github.com/cms-dev/cms/wiki/CMS-1.0.0-RELEASE-NOTES
Start development of version 1.1.0
isolate: code drop from upstream moe.git

Imported d331139bdbc6b2a7a1a1f318970734888324730b
isolate: Use cgroups how everybody else does.
Add infrastructure to compile isolate.
Convert to use isolate instead of mo-box.
Remove mo-box from source tree.
Don't error when time or memory usage is unknown.
Swap search order for isolate sandbox.

Because the directory has the same name as the executable, we don't want to
pick that up first by accident.
cmstestsuite: Fix results for timeout tests.

Now we are using the new sandbox, we can't actually detect forbidden system
calls. They really are just timeouts.
Merge branch 'master' into 64bit
