Details:

the mininal project in the unix port of contrib
(lwip-contrib/ports/unix/proj/minimal/main.c) contains explicit timer handlers
for tcp, reassembly and etharp.

the relevant code sections are `timer_testclr_evt(TIMER_EVT_TCPTMR)`... in the
main loop and and `timer_set_interval...` in the setup part.

the setup part can be dropped without replacement, the part in the mainloop
replaced with a single sys_check_timeouts() call, which does all this since
a566f9d8, i assume.

not only will this make the main program more compact, it will also allow
ditching large parts of timer.[hc] (not all; without calling timer_init, no
signals fire up at all, but i figure that's only related to the sigalarm
initialization done there), bringing the example closer to a minimal example,
and better show the features of modern lwip.
