* Follow #17746: `HasIssueContentHistory` should use expr builder to
make sure zero value (0) be respected.
* Add "doer" check to make sure `canSoftDeleteContentHistory` only be
called by sign-in users.
The xorm `Sync2` has already been deprecated in favor of `Sync`,
so let's do the same inside the Gitea codebase.
Command used to replace everything:
```sh
for i in $(ag Sync2 --files-with-matches); do vim $i -c ':%sno/Sync2/Sync/g' -c ':wq'; done
```
Change all license headers to comply with REUSE specification.
Fix#16132
