[This patchset was initially send with the wrong 'from' address to gentoo-dev@ and therefore never arrived at this mailing list]
The Erlang/OTP ecosystem, or at least parts of it, are moving away from Rebar2 and towards Rebar3. While Rebar3 is packaged in Gentoo as dev-util/rebar:3, the current rebar.eclass only supports building projects with Rebar2. This is becoming more and more of a problem. For example, Ejabberd upstream is so kind to support building with Rebar2 and Rebar3. However, I've been told by upstream that sooner or later, probably sooner rather than later, support for Rebar2 will be dropped. We should prepare for this future and support Rebar3 via an eclass. Fortunately, ::guru already has a rebar3.eclass, which was used as starting point for this patchset. Not much needed to be changed, and tests in an overlay showed that, for example, ejabberd could be simply build by swapping rebar.eclass with rebar3.eclass (no further changes where necessary). I briefly considered adding support for Rebar3 to rebar.eclass, however, after examining the eclass' code and considering the consequences of doing so, I concluded that a new rebar3.eclass is the best approach.
