Michael Brown d92551a320 [xfer] Use xfer_alloc_iob() for transmit I/O buffers on stream sockets 
Datagram sockets such as UDP, ICMP, and fibre channel tend to provide
a custom xfer_alloc_iob() handler to ensure that transmit I/O buffers
contain sufficient headroom to accommodate any required protocol
headers.

Stream sockets such as TCP and TLS do not typically provide a custom
xfer_alloc_iob() handler at present.  The default handler simply calls
alloc_iob(), and so stream socket consumers can therefore get away
with using alloc_iob() rather than xfer_alloc_iob().

Fix the HTTP and ONC RPC protocols to use xfer_alloc_iob() where
relevant, in order to operate correctly if the underlying stream
socket chooses to provide a custom xfer_alloc_iob() handler.
