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@

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@

Diff from Mikhail, thanks!

This eliminates the previous performance cost by making 'got log -d' and tog diff view compute the diffstat while building the diff in a temp file like we do with 'got diff -d'. Also, keep the current 'got log -d' UI as per stsp's suggestion. ok stsp@

Use singular form when appropriate; for example, turn the top into the bottom: 1 file changed, 1 insertions(+), 1 deletions(-) 1 file changed, 1 insertion(+), 1 deletion(-) ok op@

Accept flag parameter to optionally specify which pointers to free. This saves callers looping through the list to free pointers. ok + fix stsp@

Like got log -d, add the switch to 'got diff' to display a diffstat of changes; as per stsp's suggestion, we always include diff output with the diffstat. Disabled in gotwebd (for now :) Includes tweaks from op@ ok stsp@
