Introducing entry_saddr and entry_daddr parameters in this macro
for later use can help us record the reverse 4-tuple by analyzing
the 4-tuple of the incoming skb when receiving.

This patch moves TP_STORE_ADDR_PORTS_SKB() to a common header and removes
the TCP specific implementation details.
Previously the macro assumed the skb passed as an argument is a
TCP packet, the implementation now uses an argument to the L4 header and
uses that to extract the source/destination ports, which happen
to be named the same in "struct tcphdr" and "struct udphdr"

Put the macro into another standalone file for better extension.
Some tracepoints can use this common part in the future.

Add DCCP sendmsg trace event (dccp/dccp_probe) for
replacing dccpprobe. User can trace this event via
ftrace or perftools.
