[PATCH v3 0/5] CI: Remove Travis CI, shorten names for GH tooltips, split jobs

An update to v3, now using the "pool" names instead of a new "os" field for the job names. Before (on master):

    https://github.com/git/git/runs/4214600139

After:

    https://github.com/avar/git/actions/runs/1484426823

I peeled of the last "doc" patch based on Johannes's feedback. As with the split-up TEST job we'll take more CPU time, but if we can run in parallel take less wallclock time, but it's not really worth it for the asciidoc/asciidoctor job with how long the install v.s. build/test step takes (b.t.w. there was no change to "check-docs" running in those jobs in v2).

  CI: remove Travis CI support
  CI: use shorter names that fit in UX tooltips
  CI: rename the "Linux32" job to lower-case "linux32"
  CI: use "$runs_on_pool", not "$jobname" to select packages & config
  CI: don't run "make test" twice in one job

         looked before, [2] for a currently visible CI run using this commit,
         and [3] for the GitHub workflow syntax involved being changed here.
     
    -    Let's also add a field for the "os" and use it where appropriate, it's
    -    occasionally useful to know we're running on say ubuntu
    -    v.s. fedora (but the "-latest" suffix isn't very useful, that applies
    -    to almost all the jobs.
