In AsyncWrap::MakeCallback always return empty handle if there is an
error. In the future this should change to return a v8::MaybeLocal, but
that major change will have to wait for v6.x, and these changes are
meant to be backported to v4.x.

The HTTParser call to AsyncWrap::MakeCallback failed because it expected
a thrown call to return an empty handle.

In node::MakeCallback return an empty handle if the call is
in_makecallback(), otherwise return v8::Undefined() as usual to preserve
backwards compatibility.

Follow up from #5571 where was decided patch would land on master first.

Would it be useful to add a comment here mentioning that undefined is returned here for backward compatibility?

@trevnorris Do we want to handle both cases (being in a recursive node::MakeCallback call or not) for https://github.com/nodejs/node/blob/master/src/node.cc#L1215 and https://github.com/nodejs/node/blob/master/src/node.cc#L1174 too?

@misterdjules TBH I'm more concerned about making sure everything is backward compatible w/ v4. After async wrap is backported and public i'll go through and make those APIs return MaybeLocals instead and have them always return an empty handle.

Sounds good!

Another case I missed to mention is https://github.com/nodejs/node/blob/master/src/async-wrap.cc#L196. I don't have the time to create a repro for that use case, but I'd imagine it would be possible to write one that exposes a problem where a callback executed by node::Parser would run in a domain that was disposed, and the parser would consider that there was no error when executing that callback.

What do you think?

@misterdjules AsyncWrap::MakeCallback is completely internal. I'll change that case.

Everything's fixed up. Just need the sign-off.

Notable changes:

* child_process: “send()” now accepts an options parameter (cjihrig)
#5283
  - Currently the only option is “keepOpen”, which keeps the underlying
socket open after the message is sent.
* constants: “ENGINE_METHOD_RSA” is now correctly exposed (Sam Roberts)
#5463
* Fixed two regressions which originated in v5.7.0:
  - http: Errors inside of http client callbacks now propagate
correctly (Trevor Norris) #5591
  - path: Fixed normalization of absolute paths (Evan Lucas)
#5589
* repl: “start()” no longer requires an options parameter (cjihrig)
#5388
* util: Improved “format()” performance 50-300% (Evan Lucas)
