Link two issues of the same project (needs edit access). kind "blocks": `from` blocks `to` (to cannot be finished before from); "blocked_by": `from` is blocked by `to` (the same link written from the other end); "relates": the two are related (symmetric). An issue cannot be linked to itself, the same link cannot be added twice, an issue has at most 200 links, and both issues must be in one project. A `blocks` link that closes a cycle (A blocks B blocks A) is created anyway and the result warns about it. Both issues get a history entry, and their followers a notification. get_issue_details lists the links of an issue, with the ids unlink_issues takes.
