[Rev 01] RFR: merge-bot: allow specs to define dependencies

[Erik Helin]

> Hi all,
> 
> please review this patch that allow the specifications for the merge bot to:
> 
> 1. Have a name
> 2. Specify the names of other specifications as dependencies
> 
> The above means that the merge bot now can express a bit more complicated
> merges, such as "only merge the branch `feature` into branch `demo` if the merge
> of branch `feature-vm` into branch `feature` _and_ the merge of branch
> `feature-lang` into branch `feature` succeeded".
> 
> Testing:
> - `make test` passes on Linux x64
> 
> Thanks,
> Erik
