That had crossed my mind ... but it seems there's around 80 or 100
lines of good stuff there that'd be a shame to duplicate. If only
init_MultiFuncCall() took an extra void ** argument, and the stock
SRF_FIRSTCALL_INIT passed &(fcinfo->flinfo->fn_extra), seems like
most of it would be reusable. shutdown_MultiFuncCall would need to work
slightly differently, and a caller who wanted to be different would need
a customized variant of SRF_PERCALL_SETUP, but that's two lines.
