Code review: 8010464: Evolve java networking same origin policy

[Michael McMahon]

Hi,

This is the webrev for the HttpURLPermission addition.
As well as the new permission class, the change
includes the use of the permission in java.net.HttpURLConnection.

The code basically checks for a HttpURLPermission in plainConnect(),
getInputStream() and getOutputStream() for the request and if
the caller has permission the request is executed in a doPrivileged()
block. When the limited doPrivileged feature is integrated, I will
change the doPrivileged() call to limit the privilege elevation to a single
SocketPermission (as shown in the code comments).

The webrev is at http://cr.openjdk.java.net/~michaelm/8010464/webrev.1/

Thanks
Michael
