Revert "src: remove trace_sync_io_ from env"

ChALkeR · Trott · commit aa252ebf66c4 · 2019-08-03T20:41:50.000-07:00
This reverts commit 7fa5f54. The reverted commit breaks the logic behind --trace-sync-io, it should be enabled only at a certain point in time, while that commit enables it from the very start, causing warnings be printed for all sync io instead of sync io after the first tick of the event loop as documented. Fixes: #28913 Refs: #22726 Refs: https://nodejs.org/api/cli.html#cli_trace_sync_io PR-URL: #28926 Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: Rich Trott <rtrott@gmail.com> Reviewed-By: Colin Ihrig <cjihrig@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com>
