D2815: hgweb: extract entries() to standalone function

REVISION SUMMARY
  There was some real wonkiness going on here. Essentially, the
  inline function was being executed with default arguments because
  a function reference was passed as-is into the templater. That
  seemed odd. So now we pass an explicit generator of the function
  result.
  
  Moving this code out of makeindex() makes makeindex() small enough
  to reason about. This makes it easier to see weird things, like the
  fact that we're calling self.refresh() twice. Why, I'm not sure.
  I'm also not sure why we need to call updatereqenv() to possibly
  update the SERVER_NAME, SERVER_PORT, and SCRIPT_NAME variables as
  part of rendering an index. I'll dig into these things in subsequent
  commits.
