I think building it on-demand is probably too much effort. If it is
portable, then it should not be a problem to just build it along with
the rest of git. If it is not, then we should rethink whether it is
worth including.

I do not think we want to allow run-time switching between an embedded
solution and apache. That would mean that we have to keep two sets of
http-server config in sync.

I don't think it makes sense to embed it in git, but it could easily be

The rollout would be:

  1. add contrib/mongoose/*

  2. add test-httpd which links against mongoose, built by default in the

  3. convert lib-httpd/apache.conf into mongoose config as necessary

  4. convert lib-httpd.sh to run test-httpd instead of LIB_HTTPD_PATH

  5. delete apache.conf, LIB_HTTPD_PATH and any other apache remnants

  6. default GIT_TEST_HTTPD to yes

Step 3 is the part where I would anticipate trouble (i.e., finding out
that the new server does not do everything the tests expect).
