Revert 76880 - ChromeFrame would fail to upload POST data to the server if the webserver requested NTLM

authentication. This is due to a bug in urlmon on IE6 and IE7 which manifests itself when
the post data is passed to urlmon as an IStream. 

Fix is to pass in the uploaded data as a HGLOBAL. We always pass in a copy of the HGLOBAL
which points to the posted data to urlmon. This is to have it accessible for reissuing
navigation requests which target downloads.

Fixes bug http://code.google.com/p/chromium/issues/detail?id=62687

BUG=62687
TEST=manually at this point. As we need a server which supports NTLM authentication like IIS.
