Bug 1545226 - Enable some android gtests in netwerk/test/gtest/parse-ftp; r=jmaher With changes from bug 1548555, one of the gtests previously disabled on Android can be re-enabled, but most of the tests in netwerk/test/gtest are still problematic (some won't build for me). Differential Revision:

namespace mozilla {

 *  Generate a cryptographically secure random 64-bit unsigned number using the
 *  best facilities available on the current OS.
 *  Useful whenever a secure random number is needed and NSS isn't available.
 *  (Perhaps because it hasn't been initialized yet)
 *  Current mechanisms:
 *    Windows: RtlGenRandom()
 *    Android, Darwin, DragonFly, FreeBSD, OpenBSD, NetBSD: arc4random()
 *    Linux: getrandom() if available, "/dev/urandom" otherwise
 *    Other Unix: "/dev/urandom"
