"Security fix for CVE-2015-4000

Update to the upstream NSS 3.19.1 release, which includes a fix for
the recently published logjam attack.

The previous 3.19 release made several notable changes related to the
TLS protocol, one of them was to disable the SSL 3 protocol by
default.

For the full list of changes in the 3.19 and 3.19.1 releases, please
