Various small clean-up operations (Azure#3032)

Among other things, this also removes `log` from the workspace
`Cargo.toml`.
Nothing was referencing it, and looking at `git blame` I can find no
reason I added it with only a major.minor version in 78ac814.
A review of `Cargo.toml` shows that I added a couple in explicitly -
`litemap` and `zerofrom` - to satisfy some Dependabot issues in case the
`Cargo.lock` file is every regenerated, but those are full semvers.
`log` first appeared in `Cargo.lock` when I first committed it to the
repo.
