hbos@webrtc.org changed reviewers:
+ tommi@webrtc.org

[hbos, 2016-06-09 13:57:06]

Please take a look, tommi.

Note: I will hold of landing this until a chromium CL
(https://codereview.chromium.org/2033353002) has landed that makes Chromium stop
using the DtlsIdentityStoreInterface.

[hbos, 2016-06-10 10:13:28]

Note to self: Also need to remove
https://cs.chromium.org/chromium/src/third_party/libjingle/libjingle.gyp?q=li...
and corresponding BUILD.gn before landing this as to not break Chromium FYI
bots.
