commit 8de1662514e5191715055479b503dbb016899e84 Author: Mike Hommey mh+mozilla@glandium.org Date: Fri Feb 8 13:48:36 2019 +0000

Bug 1516642 - Add a function declaration for arc4random_buf in expat. r=peterv

The function has been in bionic (Android's libc since the first commit in the upstream repository), but it's not been in stdlib.h until recently. As it happens, we have a similar declaration in xpcom/base/nsUUIDGenerator.cpp.
