Small tweak to cover the case where users specify paths to be committed such that none of the paths modified by a backout or cherrypick operation are in the commit. In this case, the logmsg ref will remain in refs/got/worktree to be used when the user does run a commit involving the affected paths. ok stsp@

Make sure we have a parent id first to avoid dereferencing a NULL pointer with the got_object_open_as_commit() call. ok op@ and stsp@

- try to delete using git - try to delete multiple branches in one go - verify the ref-list reported by the server before and after the deletion suggested / ok stsp

Allow clients to run "got send -d" against gotd. Clients will send a zero-id as new id for a reference and, in the special but more common case of just deleting and not updating, no pack file will be sent. ok and tweaks by stsp@

Tests only cover the -lX interface to list and delete logmsg refs created by previous backout and cherrypick operations. Further tests are needed for revert and commit coverage to ensure that the correct log messages of bo/cy commits are loaded into the editor when 'got commit' is run, and that only the refs used to populate the editor for the new commit are deleted. Potential printf issues observed by op remain in the diff; noted here as a reminder to do a sweep at some point in the future as there are other such instances in cherrypick.sh and possibly elsewhere in regress. Reviewed as part of previous commit introducing logmsg ref support for backed-out/cherrypicked commits. ok stsp@

Create new logmsg references used to populate the editor with the log messages of backed-out and cherrypicked commits when 'got commit' is run. We use versioned path state heuristics during revert and commit commands in an effort to ensure the editor is only populated with the log messages of backed-out and/or cherrypicked commits involving paths with local changes that are being committed. This is an implementation of an initial idea and algorithm designed by stsp. inputs, improvments and ok stsp@

Keep track of parent commits that will be processed as part of looping over the commit queue provided by the main process, and do not add these commits to the queue again. Fixes pointless traversal of commits on the queue which will simply be skipped. The end result is the same either way. ok tracey

got-read-pack forgot to send a tree-enumeration-done message to the main process if the tree of a given commit had already been traversed. The main process would then not add the corresponding commit to the pack file, even though it should be added. Found while using 'got send' towards gotd in order to populate an empty repository on the server with non-trivial history, where some commits always ended up missing due to this bug. ok tracey
