Bug in wap_push_ppg.c ?

The function send_to_pi () takes a first argument of HTTPClient *c.
This is passed directly to http_send_reply (c...). If the c is NULL
http_send_reply () crashes as it immediately deferences c.

I don't think send_to_pi () should assume that the PI is still around
and hence should check that the HTTPClient ptr is non-NULL before
invoking http_send_reply ().
