improve cyclic dependency error message output #739
Description
Cyclic dependencies are correctly detected (see f.e. #734), but knowing which target is responsible for it isn't straightforward.
:: Package pdftk not found in repositories, trying AUR...
:: resolving dependencies...
tsort: -: input contains a loop:
tsort: gcc-gcj-ecj
tsort: gcc63-gcj
tsort: gcc63
tsort: -: input contains a loop:
tsort: gcc-gcj-ecj
tsort: gcc63-gcj
:: dependency cycle detected
This isn't an issue when explictly installing a specific package, but can be when updating as it might be difficult to know which target is responsible for the issue. Modify the error message to display the target, similarly as done in #173.
:: dependency cycle detected (target -> dep1 -> dep2 -> dep1)
This might not be straightforward to do with tsort, but might be easier done in conjunction with the solver provided by auracle (see #720).
