Affected core subsystem(s)

buffer

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, v0.12 and v0.10

I'd like @nodejs/lts to have a discussion about this on 0.12 and 0.10 and whether we can justify it since 0.10 is in maintenance and 0.12 is about to be maintenance.

Yep. Agreed. Backporting this to v0.12 and v0.10 is a bit ugly because of
smalloc. Not impossible, just ugly.

@nodejs/ctc ... the LTS WG discussed this PR (along with #5748 and #5751) today and decided that the command line flag should land in v4, v0.12 and v0.10. It was decided that the new constructor APIs should be ported to v4 and not to v0.12 or v0.10. Before I get these command line flag PRs landed, we wanted to get a quick sign off from the CTC.

CTC decision today to hold off landing this in v4 for now. Will keep the PR open. @nodejs/lts

@nodejs/ctc ... is it time to go ahead and get this landed? I can get this updated and there's a minor fix to make but can get it landed in time for v4.5

@jasnell I have a backport of the new Buffer API at https://github.com/ChALkeR/io.js/commits/buffer-v4.x-squashed (unfinished, hope to file a PR soon), and I hope to see a minor release of 4.x with both the new API and the flag backported.

Update: the branch link was wrong, fixed
