This test duplicates some of what is in internal/artifacts but
@grzesiek and I felt it was important to have an integration test that
also covers the route to this resource.

Uses escaper from mime/multipart/writer.go.

  Develomentmode ended up the wrong way around
  Move test helpers into seperate package

Refactor upstream

Rationale: the code has become a tangled mess of global variables and
types that hang together when they need not. For example: every HTTP
handler uses a 'gitRequest'?? I want to clean this up and see if I can
move some things into internal packages.

Apart from using internal packages we now use http.Handler where we can,
and fewer global variables.

We need to use `$(shell find` to find files from all subdirectories

Fix /api/v3/projects routing error

Non-special API requests were getting special treatment, which
resulted in 500 errors. This change avoids the special treatment and
adds tests that assert that regular API requests should be left alone
by gitlab-workhorse.

We should test with what actually happens, e.g. foo%2Fbar, not
foo/bar.
