Fix timers

[loyd]

Adoption of nodejs/node-v0.x-archive#8120.

Unfortunately, I don't fully understand what @bnoordhuis meant. However, the test runs without it, i.e. check it out correctly this._onTimeout.

Sorry for letting this pull request fall through the cracks. I think it would be best (in the hope of merging) to split the pull request into separate PRs for each individual commit (and perform a rebase on each, as necessary). Some of these commits will probably bring more discussion than the others and I don't think these can all be merged at once.

@loyd are you still up to updating this PR? Going to close otherwise.

[brendanashworth]

@Fishrock123 at least two of the three commits here I would like to see merged into the repository, but I think since they are packaged all together they aren't very welcomed. If you could hold off on closing this so I could resubmit the commits one at a time, that'd be great - I'd be up to update this for him.

[loyd]

Sorry for the delay in response.
@brendanashworth What kind of commits do you mean?

[brendanashworth]

@loyd thanks for rebasing. I'd like to see ad60db8 merged as I believe that would be an easy semver-patch - and therefor should be treated in a separate pull request. 1c9e35a I would like to see merged in eventually, but it could very well be interpreted as a semver-major change and would take longer to merge in.

I'm not entirely sure what fe805ef fixes, so I'm not going to take stance on that - but as these commits individually are very different from eachother, putting them in one pull request is the fast track to not being merged and the only way I can see these getting merged would be re-submitting pull requests individually, one for each commit.

[brendanashworth]

All the commits in this pull request need some serious rebasing by now, and since they need to be resubmitted in separate pull requests anyways, I'll close this for now. We'd still welcome new pull requests with these changes, but as they are now (bundled and in need of a rebase), we cannot continue to work on them from this PR. If you disagree, you can always reopen this. Thanks!

p.s. I tried rebasing the "fix for unref'd timers", but I got a segfault. 😛

I need to look at this tomorrow. See also #1151, #1152, and others.
