  Log Message:
  -----------
  Add GitHub Actions configuration

Configure a build workflow running on pushes and pull requests
that does the same build logic as support/mksnapshot does, except
for testing --enable-largefiles (which is irrelevant on GitHub
Actions runners).

Tell dependabot to send PRs for updates to any workflow actions
we use (currently only checkout).

  Check return status of fgets

The version of Ubuntu used for GitHub Actions requires the return
status of fgets be tested or -Wunused-result fails.  Add explicit
checks to those fgets invocations that weren't already tested.

  Log Message:
  -----------
  Remove innfeed debugWrites support

I have never used this in decades of working on INN, and it was
generating compiler warnings.  It's almost as easy to add in
approrpriate print statements than enable this flag, which required
a source modification anyway.

This was apparently intended for use with a die handler, but
there was no mechanism to call it.
