In icmp.c it was impossible to intercept
ICMP Echo Requests. Changed the handler
registration to allow intercept.
In ping.c any ICMP segment was considered
to be an ICMP Echo Reply in the handler
registered. Changed it to count only
ICMP Echo Reply.
Added the possibility to send an RST flag
in TCP in order to abort a connection.

	* include/net/net.h: Add __tcp_abort prototype.

	* src/net/icmp.c: The default handler can be replaced by a
	user defined handler which handles all ICMP segments.

	* src/net/ping.c
	(handle_icmp): Only ICMP Echo Reply segments must be counted and
	ICMP Echo Requests are handled in the user defined handler.

	* src/net/tcp.c
	(do_abort, __tcp_abort): Send an RST flag in order to abort a
	connection. May use a delay to send the flag.
