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.
The full details of the change on written up in the netlib newsgroup.

Tested on win32. Tested to build on win32 and solaris.
This patch fixes bug 52963, bug 52965, and bug 52973.

52963: nsIPluginStreamListener::OnStartBinding isn't always called:
Added new ivar, mStartBinding:
* Set to PR_TRUE after nsIPluginInstancePeer::OnStartBinding() has
* been called. Checked in ::OnStopRequest so we can call the
* plugin's OnStartBinding if, for some reason, it has not already
* been called.
52965: Length isn't always set:
rv = channel->GetContentLength(&length);
// it's possible for the server to not send a Content-Length. We should
// still work in this case.
if (NS_FAILED(rv)) {
mPluginStreamInfo->SetLength(-1);
}
else {
mPluginStreamInfo->SetLength(length);
}
52973: nsIHTTPHeaderListener called before nsIPluginStreamListener::NewStream
This fix required rolling back Andrei Volkov's change to the signature
of nsPluginStreamListenerPeer::SetUpStreamListener(). In order to call
the plugin with the headers before the NewStream is sent, we need the
nsIChannel.

This simple fix just adds parameters to an existing method in an XPCOM
safe way, by defining a new method at the end of the interface
definition with the additional parameters.
Original method:
NS_IMETHOD
GetURL(nsISupports* pluginInst,
const char* url,
const char* target = NULL,
nsIPluginStreamListener* streamListener = NULL,
const char* altHost = NULL,
const char* referrer = NULL,
PRBool forceJSEnabled = PR_FALSE) = 0;
New method:
NS_IMETHOD
GetURLWithHeaders(nsISupports* pluginInst,
const char* url,
const char* target = NULL,
nsIPluginStreamListener* streamListener = NULL,
const char* altHost = NULL,
const char* referrer = NULL,
PRBool forceJSEnabled = PR_FALSE,
PRUint32 getHeadersLength = 0,
const char* getHeaders = NULL) = 0;
I have modified nsPluginHostImpl.h to include this new method, and
modified nsPluginHostImpl.cpp so that its GetURL calls GetURLWithHeaders
with null values for the last two params.

This change allows the plugin to have a greater degree of control over
the plugin lifecycle. This change makes it possible for the plugin to
tell mozilla:
1. Whether or not they want to allow the browser to cache their
instance. Default is yes, do allow the browser to cache their instance.
2. If they answer no to 1, that is, no the plugin does not want the
browser to cache their instance, do you want the shutdown calls to be:
a.
inst->SetWindow(nsnull);
inst->Stop();
inst->Destroy();
b.
inst->Stop();
inst->Destroy();
inst->SetWindow(nsnull);
a. is the default.

Detail:
This fix was requested by Stanley Ho of the Sun Java Plugin Team. A
conference call between Eric Krock, Andrei Volkov, Sun, Adobe and other
plugin vendors was used to agree on the above solution.
M modules/plugin/public/nsplugindefs.h
M modules/plugin/nglsrc/nsPluginHostImpl.cpp
M modules/plugin/nglsrc/nsPluginViewer.cpp
M layout/html/base/src/nsObjectFrame.cpp

This bug fix was suggested by Stanley Ho <stanley.ho@eng.sun.com>.
Stanley proposed we overload the meaning of the nsIPluginStreamListener
argument to nsIPluginManager::{GetURL,PostURL}() so that it also may
implement an interface for reading headers. Thus, the browser could QI
the plugin's nsIPluginStreamListener instance to this headers reading
interface and send the plugin the headers from the response.
I have implemented Stanley's above proposal. I have defined a new
interface, nsIHTTPHeaderListener.idl with one method:
/**
* Called for each HTTP Response header.
* NOTE: You must copy the values of the params.
*/
void newResponseHeader(in string headerName, in string headerValue);
To affect this fix, I have added a new private method
nsPluginStreamListenerPeer::
ReadHeadersFromChannelAndPostToListener(nsIHTTPChannel *httpChannel,
nsIHTTPHeaderListener *listener)
Then, modified nsPluginStreamListenerPeer::OnDataAvailable() to call
this method BEFORE reading the content data. However, this fix makes
two important assumptions I would like to check out:
* Assumption
* By the time nsPluginStreamListenerPeer::OnDataAvailable() gets
* called, all the headers have been read.
* Assumption:
* The return value from nsIHTTPHeader->{GetFieldName,GetValue}()
* must be freed.
The following files are included in this fix:
A modules/plugin/public/nsIHTTPHeaderListener.idl
A modules/plugin/public/makefile.win

This fix makes it so nsIPluginManager::PostURL() works correctly in the
case of a null target and non-null streamListener.
The fix was to add parameters to NewPluginURLStream() for headers and
post data:
NS_IMETHOD
- NewPluginURLStream(const nsString& aURL, nsIPluginInstance *aInstance, nsIPluginStreamListener *aListener);
+ NewPluginURLStream(const nsString& aURL, nsIPluginInstance *aInstance,
+ nsIPluginStreamListener *aListener,
+ void *aPostData = nsnull, PRUint32 aPostDataLen = 0,
+ const char *aHeadersData = nsnull,
+ PRUint32 aHeadersDataLen = 0);
And to add a new method to correctly send the headers to the channel:
+ NS_IMETHOD
+ AddHeadersToChannel(const char *aHeadersData, PRUint32 aHeadersDataLen,
+ nsIChannel *aGenericChannel);
Files in this fix:
M modules/plugin/nglsrc/nsPluginHostImpl.cpp
M modules/plugin/nglsrc/nsPluginHostImpl.h
Right now, nsIPluginManager::PostURL() has parameters for
postHeadersLength and postHeaders. However, nothing is being done with
these parameters. This bug fix utilizes these params for their intended
purpose: to allow the plugin the ability to add HTTP headers to a POST
data stream.
Important assumptions made by this fix:
* postHeadersLength is the correct length for postHeaders.
* postHeaders is a buffer of headers in the form
"HeaderName: HeaderValue\r\n"
each header, including the last, MUST be followed by "\r\n".
To affect this fix I had to modify the following files:
M docshell/base/nsDocShell.cpp
M docshell/base/nsDocShell.h
M docshell/base/nsWebShell.cpp
M modules/plugin/nglsrc/nsPluginViewer.cpp
M docshell/base/nsWebShell.h
M layout/html/base/src/nsObjectFrame.cpp
M modules/plugin/nglsrc/nsIPluginInstanceOwner.h
M modules/plugin/nglsrc/nsPluginHostImpl.cpp
M modules/plugin/nglsrc/nsPluginInstancePeer.cpp
M webshell/public/nsILinkHandler.h
Basically, it involved clearing a path so the headers arguments can make
it down to nsIPluginInstanceOwner::GetURL()'s implementation in
nsObjectFrame.cpp, where an nsIInputStream is made of the headers.

r=av,waterson
Here is what I believe to be the correct fix.
This post correspondes to the fix,
second iteration attachments.
M modules/plugin/nglsrc/nsIPluginInstanceOwner.h
M modules/plugin/nglsrc/nsPluginHostImpl.cpp
M modules/plugin/nglsrc/nsPluginInstancePeer.cpp
M modules/plugin/nglsrc/nsPluginViewer.cpp
M layout/html/base/src/nsObjectFrame.cpp
This checkin modifies nsIPluginInstanceOwner::GetURL
to have a length parameter for the post data.
