From 1e4884f615b20946411a74e41eb9c6aa65e2d5f3 Mon Sep 17 00:00:00 2001 From: Adam Langley Date: Thu, 24 Sep 2015 10:57:52 -0700 Subject: external/boringssl: sync with upstream. This change imports the current version of BoringSSL. The only local change now is that |BORINGSSL_201509| is defined in base.h. This allows this change to be made without (hopefully) breaking the build. This change will need https://android-review.googlesource.com/172744 to be landed afterwards to update a test.
