+- update to NSS 3.37.3
+  * required by Firefox 61.0
+  Notable changes:
+  * The TLS 1.3 implementation was updated to Draft 28.
+  * Added HACL* Poly1305 32-bit
+  * The code to support the NPN protocol has been fully removed.
+  * NSS allows servers now to register ALPN handling callbacks to
+    select a protocol.
+  * NSS supports opening SQL databases in read-only mode.
+  * On Linux, some build configurations can use glibc's function
+    getentropy(), which uses the kernel's getrandom() function.
+  * The CA list was updated to version 2.24, which removed the
+    following CA certificates:
+    - CN = S-TRUST Universal Root CA
+    - CN = TC TrustCenter Class 3 CA II
+    - CN = TÜRKTRUST Elektronik Sertifika Hizmet Sağlayıcısı H5
+  * Fix build on armv6/armv7 and other platforms (bmo#1459739)
