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@

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@

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@

patch by Josiah Frentsos

Add new got_diff_blob_cb() implementation to compute added/removed line metrics for a given diff. This enables displaying a diffstat with 'got log -d'. As per suggestion from stsp, change tog diff view to display the diffstat by default. ok stsp@

The -h and -V/--version flags must be given before the command; with those flags the command is actually optional, but don't over-complicate the usage string with these nitpicks. ok/improvements stsp@

Similar to `git init -b`. Includes a change to `got import` behaviour such that "main" is no longer hardcoded by default; instead, we import to the branch resolved via the repository's HEAD reference unless `got import -b` is used, and only if HEAD cannot be resolved to a branch do we fallback to "main". includes fix plus ok from stsp@
