-----------
Missing validation of frameInfo in WebFrameProxy::getFrameInfo()
https://bugs.webkit.org/show_bug.cgi?id=315006
rdar://176816153
Reviewed by Ryosuke Niwa.
Harden WebFrameProxy::getFrameInfo() so the security-relevant fields of
the FrameInfoData struct returned by WebProcess are now validated.
In case of mismatch, we overwrite with correct values and log an error
message instead of doing a MESSAGE_CHECK, to reduce risk.
