585fc3e554 Add __libc_arc4random_unlimited_entropy. 
Let the caller know when libc has an entropy source and arc4random is safe.
This is useful for the callers that want entropy, but don't absolutely need it.

Bug: http://b/27729263
Test: booted angler-userdebug w/ safestack

78a52f19bb Attempt to use arc4random where getauxval(AT_RANDOM) is used. 
When arc4random can get entropy (which is true for basically everyone
but init on kernels that don't support getrandom), use it instead of
AT_RANDOM.
