check for {sync,true} and {stream,{self,once}} in HTTP client

[Adam Kocoloski]

Hi, it looks like the HTTP client checks for the combo of {sync,true}  
and {stream,self} and returns an error, but if {stream,{self,once}} is  
used instead the process will just hang.  Here's a simple patch.  Best,

Adam
