Revising nsIChannel to allow for overlapped i/o. This consists of three parts:
1. Factoring nsIChannel into a protocol specific part, the nsIChannel, and a socket specific, the nsITransport.
2. Derive the nsIChannel from a nsIRequest.
2. Changes the notification system from necko and the URILoader to pass the nsIRequest interface instead of nsIChannel interface.
This goal stems from wanting to be able to have active AsyncRead and AsyncWrite operations on nsSocketTransport.
This is desired because it would greatly simplify the task of maintaining persistent/reusable socket connections
for FTP, HTTP, and Imap (and potentially other protocols). The problem with the existing nsIChannel interface is
that it does not allow one to selectively suspend just one of the read or write operations while keeping the other active.

as this code has been reconsolidated in the base class for
all to use. For everyone, if the mime type is unknown or octet,
then try to guess a content type by file extension in doContent.
Also, if we can't find a mime type, create a new one for all platforms
so we don't need to bring up the ucth dialog.

we are already done with the download. Break apart
SaveTodisk and LaunchWithTempFile into to separate
methods. never try to really open or save to disk
until we are sure we've brought up the progress window.
Bug #61947 --> pass in the initial time when we started the download via getDownloadInfo so
the progress dialog can use this information.

entry for this mime type.
Bug #57364 --> look up content type to file extension mappings using the windows mime registry.
Bug #65872 --> if we get a content type of unknown or octet, try to ignore that content type
and extract the extension from the url and looking that up to see if we can get a better
content type.

and force any Refresh urls back through the original window
context that initiated the helper app download. This solves
the problem where the user clicks on a link to download
content (either to disk or to a helper app) and that document
contains both a redirect for the actual content and a REFRESH
header which is used to point at a page the content provider
wants to see after the download is complete.
