Normalize all paths to run the same, common code for pre-request setup

from the primary request, redirects and sub-requests.

  This will significantly reduce opporunities for inconsistancy (such
  as Ian observed, and as I repaired only a month ago.)

  This promotes process_request_internal to an ap_ namespace protected
  entity in server/request.c (from it's old home in http/http_request.c)
  since this fn has no http specifics.

Reviewed (in concept): Cliff Woolley, Ian Holsman
