[BlackBerry] Synchronize platform/network/blackberry

[BlackBerry] Synchronize platform/network/blackberry
https://bugs.webkit.org/show_bug.cgi?id=81874

We changed a lot in these files locally. But the changes are not upstreamed.
It is not convenient to do the other upstreaming work based on these differences.
So upstream these changes.
