We take a best-effort approach since information for these fields are not well supported on all platforms. user.LookupId+user.LookupGroupId is currently 15x slower than os.Stat. For performance reasons, we perpetually cache username and groupname with a sync.Map. As a result, this function will not be updated whenever the user or group names are renamed in the OS. However, this is a better situation than before, where those fields were not populated at all.

This commit relaxes SendmsgN behavior of introducing a dummy 1-byte payload when sending ancillary-only messages. The fake payload is not needed for SOCK_DGRAM type sockets, and actually breaks interoperability with other fd-passing software (journald is one known example). This introduces an additional check to avoid injecting dummy payload in such case.

Right now we only kind of sort of trace GC STW events. We emit events around mark termination, but those start well after stopping the world and end before starting it again, and we don't emit any events for sweep termination. Fix this by generalizing EvGCScanStart/EvGCScanDone. These were already re-purposed to indicate mark termination (despite the names). This commit renames them to EvGCSTWStart/EvGCSTWDone, adds an argument to indicate the STW reason, and shuffles the runtime to generate them right before stopping the world and right after starting the world, respectively. These events will make it possible to generate precise minimum mutator utilization (MMU) graphs and could be useful in detecting non-preemptible goroutines (e.g., #20792).

Found with mvdan.cc/unindent. It skipped the cases where parentheses would need to be added, where comments would have to be moved elsewhere, or where actions and simple logic would mix. One of them was of the form "err != nil && err == io.EOF", so the first part was removed.
