Remember user's decisions on SSL errors.
After CL: https://codereview.chromium.org/369703002, Android
WebView just has a NULL SSLHostStateDelegate. So it does not remember
any user decisions on SSL errors. This is a regression of behavior from
JB behavior: Larger error codes are assumed to have higher severity. And
if the user has allowed an SSL error with a high severity, the user
won't be prompted for a lower severity SSL error.
K and L behavior: A specific SSL error will be allowed only if the error
bit field is a subset of previously allowed error codes.
trunk behavior for webview (without this patch): We don't remember
user's decision at all.
Maintain the same behavior with K and L.
