src: declare process-related C++ methods in node_process.h

joyeecheung · addaleax · commit d4ef9220ad72 · 2019-01-15T19:57:08.000+01:00
Instead of in node_internals.h. Also move process property accessors that are not reused into node_process_object.cc and make them static. PR-URL: #25397 Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Anna Henningsen <anna@addaleax.net>
