core: Added void to declarations of functions with empty argument list

In C language, a declaration in the form int f(); is equivalent to int f(...);, thus being able to accept an indefinit number of parameters. With the -Wstrict-prototypes GCC options, these declarations are reported as "function declaration isn’t a prototype".
On some cases, this may trick the compiler into generating unoptimized code (like preparing to handle variadic argument list).
In all cases having a declaration int f() and a definition inf f(int) is missleading, even if standard compliant.
This is still Work in Progress. (maybe adding the -Wstrict-prototypes option to default is desireable)

tcp: enable tcp statistics

tcp statistics implemented using the counters api.
Enabled by default (unless compiles with -DNO_TCP_STATS).
E.g.:
$ sercmd cnt.grp_get_all tcp
{
con_reset: 4
con_timeout: 0
connect_failed: 6
connect_success: 1
established: 12
local_reject: 0
passive_open: 11
send_timeout: 0
sendq_full: 0
}

tcp: internal macro-hooks for stats & events

- added macros for tcp statistics (for now empty, keeping
more statistics will only involve redefining them):

TCP_STATS_ESTABLISHED(state) - new connection established
TCP_STATS_CONNECT_FAILED() - new outgoing connection failed
TCP_STATS_LOCAL_REJECT() - new incoming connection rejected
(max. no exceeded)
TCP_STATS_CON_TIMEOUT() - connection closed for being idle too
long
TCP_STATS_SEND_TIMEOUT() - send fails due to a timeout
TCP_STATS_SENDQ_FULL() - send fails because of the buffering
capacity being exceed (async mode
only)

- added macros for various tcp events (for now some of them are
used for logging):

TCP_EV_CONNECT_RST(...) - connect attempt received RST
TCP_EV_CONNECT_UNREACHABLE(...)
TCP_EV_CONNECT_TIMEOUT(...)
TCP_EV_CONNECT_NO_MORE_PORTS(...)
TCP_EV_CONNECT_ERR(...) - other connect error
TCP_EV_SEND_TIMEOUT(...)
TCP_EV_SENDQ_FULL(...)
TCP_EV_IDLE_CONN_CLOSED(...)
