Add support for long messages in IE 6/7 to IFPC

For IFPC transport, split long messages (> 2000 characters) into chunks.  Necessary in order to avoid URL character limit on IE 6 & 7.

John, is this relevant anymore?

Not for any use cases I'm aware. @Javier, who on your side still makes use
of IFPC?

Safe to apply then?

Also, safe to get rid of legacy mode?

Well, anyone using the old RPC library (non-trunk, Shindig 2.0.x) will be using
IFPC on IE 6 & 7.  Until the Flash transport is fully baked and tested, this is
what will be used.

And unlike the other transports, there is a message length limit with IFPC,
unless this patch is applied.

So this would be more as a fix for Shindig 2.0.x, since the trunk (and
eventually Shindig 3?) will use the Flash transport.

Forgot to mention:  OpenAjax Hub also makes use of the RPC library, but I try to
stick to released versions and not pick from trunk.  So Hub is also using IFPC
for IE 6/7 and will move up to Flash transport on next Shindig release.

Yes, and no. :(
