It looks like the github windows build environment is not correctly
inheriting environment variables. Which is strange, as that has not
been changed with the recent updates. Include the vars directly as a
workaround (and plan to refactor later)
* Address shellcheck concerns with n2n_gateway.sh script
* Rename n2n_gateway.sh to live with all the other scripts (and update docs)
* Rename hack_fakeautoconf to make it clearly a shell script
* Address shellcheck concerns with hack_fakeautoconf.sh
* Rename python scripts to match other n2n tools
* Fix windows compile - when streamlining the use of hack_fakeautoconf.sh, I forgot to update all uses of this script
