Log Message:
Update to 3.19.1

Changelog:
Network Security Services (NSS) 3.19.1 is a patch release
for NSS 3.19.

No new functionality is introduced in this release. This patch
release includes a fix for the recently published logjam attack.

Notable Changes:
* The minimum strength of keys that libssl will accept for
  finite field algorithms (RSA, Diffie-Hellman, and DSA) have
  been increased to 1023 bits (bug 1138554).
* NSS reports the bit length of keys more accurately.  Thus,
  the SECKEY_PublicKeyStrength and SECKEY_PublicKeyStrengthInBits
  functions could report smaller values for values that have
  leading zero values. This affects the key strength values that
  are reported by SSL_GetChannelInfo.

The NSS development team would like to thank Matthew Green and
Karthikeyan Bhargavan for responsibly disclosing the issue in
bug 1138554.

The HG tag is NSS_3_19_1_RTM. NSS 3.19.1 requires NSPR 4.10.8 or newer.
