* (general) More cleaning up of stream abuse, isisd should be
back to previous functionality. Replace various XMALLOC+memset's
with XCALLOC
* isis_tlv.c: (tlv_add_padding) use stream_put to clear the stream
rather than forward endp, as isisd reuses streams.
* isis_pdu.c: (process_lsp) cleanup direct reference to stream endp
(send_lsp) manual copy of a stream cleaned up to use stream_copy.
* isis_network.c: (isis_recv_pdu_bcast) replace direct memcpy with
stream_write
(isis_recv_pdu_p2p) replace recvfrom directly into stream with
stream_recvfrom. Remove dangerous and now unneeded manual update
of endp.
(isis_recv_pdu_bcast / non-GNU_LINUX) Replace direct memcpy with
stream_write.
(isis_recv_pdu_p2p) replace read direct into stream with
stream_read_try, and hence remove the manual update of endp.
* isis_lsp.c: (lsp_update_data) manual stream dup replaced with
stream_dup.
(lsppdu_realloc) mempcy into stream data replaced with stream_put.
(lsp_build_nonpseudo) remove mysterious stream_forward_endp's -
which were originally stream_set_putp - shouldn't be needed
now that all the manual fiddling of private stream data has been
corrected.
(build_topology_lsp_data) remove unneeded twiddling of endp,
appears to be due to lsppdu_realloc(), but it appears to sort of
do the right thing wrt streams.
