We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new

I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

That matches the other CSV names (HSM was the first, so it was written
before the pattern emerged).

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?
And delete unused gossipd/gossip.h.
