When a client requests the v2 protocol over HTTP, they set the Git-Protocol header. Webservers will generally make that available to our CGI as HTTP_GIT_PROTOCOL in the environment. However, that's not sufficient for upload-pack, etc, to respect it; they look in GIT_PROTOCOL (without the HTTP_ prefix). Either the webserver or the CGI is responsible for relaying that HTTP header into the GIT_PROTOCOL variable. Traditionally, our tests have configured the webserver to do so, but that's a burden on the server admin. We can make this work out of the box by having the http-backend CGI copy the contents of HTTP_GIT_PROTOCOL to GIT_PROTOCOL. There are no new tests here. By removing the SetEnvIf line from our test Apache config, we're now relying on this behavior of http-backend to trigger the v2 protocol there (and there are numerous tests that fail if this doesn't work). There is one subtlety here: we copy HTTP_GIT_PROTOCOL only if there is no existing GIT_PROTOCOL variable. That leaves the webserver admin free to override the client's decision if they choose. This is unlikely to be useful in practice, but is more flexible. And indeed, it allows the v2-to-v0 fallback test added in the previous commit to continue working.
