When is this used? Testing only?

SetTransportSecurityStateSourceForTesting()?

[martijnc, 2017/03/13 21:51:40]

Yes, this is only used in tests. Renamed.

+// (transport_security_state_static.h).
+void NET_EXPORT_PRIVATE SetDefaultTransportSecurityStateSource();

Why is this needed? Our normal pattern for overriding defaults let's a nullptr
be seen as the 'reset to default' equivalent.

[martijnc, 2017/03/13 21:51:40]

This was used to set the source back to the default so that other tests weren't
affected.

Didn't know that, thanks. Removed.
