+Subject: [PATCH] Use system NSS only for certificate handling
+
+Compiling against NSS 3.23 fails with current Chromium. Also, with NSS
+3.21 there are failures connecting to e.g. google.com.
+
+Fix this by adapting the setup endorsed by upstream Chromium: BoringSSL
+is always used for cryptography, and NSS only for certificate handlng.
+
+Patches included in 3rdparty update:
+
+0a385bb [backport] Call EnsureNSSHttpIOInit in the chimera build.
+0472123 Fix build against newer NSS
+90c62c4 <third_party/libpng> [Backport] update to libpng 1.2.56
+34857b8 <third_party/libpng> [Backport] Stop large iCCP chunks causing delays and "Aw Snap!"
