Subject: events: move EE c'tor guts to EventEmitter.init
X-Git-Tag: v0.11.10~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=54da818e4bec4e5a0a1928441ec6fc90b4903ba0;p=platform%2Fupstream%2Fnodejs.git

events: move EE c'tor guts to EventEmitter.init

After landing 6ed861d it is no longer possible to reliably monkey-patch
the EventEmitter constructor. However there's valid use cases for that,
and makes for easier debugging. Therefore, move the guts of the
constructor to a separate function which is monkey-patchable.

Closes #6693
