Description of change
This backports the --zero-fill-buffers command line flag introduced in master. When used, all Buffer and SlowBuffer instances will zero fill by default.
This does not backport any of the other Buffer API or behavior changes.
Note: My intent is to open similar backports for
--zero-fill-buffer
in v5, v4, and v0.12/cc @trevnorris
