upgrade the dependencies to their latest version

[osdevisnot]

This pr upgrades tap and tap-parser to their latest version. I also tool the opportunity to upgrade concat-stream.

Looking forward to any feedback.

Few notable upstream changes:

• tap-parser changed the signature - requiring us to create a class with new keyword
• tap-parser added a parser.fullname field -
  tapjs/tap-parser@287e137 - my approach in this PR is to explicitly delete the parser.fullname property, but I can change the expectations too if that's more preferred.

Looking at the test failures, we might need to update the supported node version based on dependencies.

Notably, tap started depending on async/await, const and other modern javascript features, which would require us to bump supported node version from ~1.0 to ~6.0 at least.

We will likely never drop any version of node that's currently supported. There's a reason we haven't upgraded all of the dev deps :-)

what's the difference in travis yml versions?

The motivation behind this PR is to be able to use the parallel testing feature introduced in tap version 13.

If I may ask, is there a specific reason to support node version if it reaches EOL status on node.js

[ljharb]

EOL status is irrelevant. People use it, and supporting it makes their platform upgrades easier.

Also, tape is used in browsers, and there are still people using IE 8 and 9.

tape’s tests are more than fast enough; parallel testing isn’t that much of a carrot for me.

[osdevisnot]

ok, makes sense. Feel free to close this PR unless we want to change the support policies.

[ljharb]

@osdevisnot i'm still interested in some of the changes here; if you can get concat-stream updated to v2, and improve the editorconfig check, that's still worth getting in.

[osdevisnot]

great, closing this in favor of #506.

[ljharb]

Looks like the concat-stream update isn't going to work in node < 4.

[ljharb]

As such, I'm going to close this and #506; since it turns out, every non-updated dev dep was because updating it would break things :-)
