> In a spdy session, plugin will hang if reload the page several times in browser.
> Debug log:
> {code}
> (spdy.plugin) spdy_vconn_io:297 received 738 bytes
> (spdy.plugin) spdy_vconn_io:297 received 754 bytes
> (spdy.plugin) spdy_vconn_io:297 received 1442 bytes
> (spdy.plugin) spdy_vconn_io:297 received 1458 bytes
> ....repeat on each reload request....
> {code}
> Some debug info,  FYI:
> When hanging, at spdy.cc:204 consume_spdy_frame(), nbytes from TSIOBufferBlockReadStart will not grow. So (header.datalen <= (nbytes - spdy::message_header::size) can not pass test. 
> nbytes from TSIOBufferBlockReadStart is the available bytes of current block, which I think should get from TSIOBufferReaderAvail(io->input.reader). However, after replacing with TSIOBufferReaderAvail, other issues will raise: parsing request header will fail or crash when decompressing header.
