Until now, trigger.c didn't know about SPI, and spi.c didn't know
about triggers. The intersection was left to referencing code, like
PLs. Is there any other common code among the PLs dealing with this
intersection? If so, maybe a new triggerspi.c file (or
spitrigger.c?) would make sense. Possibly it could make sense from
a code structure PoV even for a single function, but it seems kinda
iffy for just this function. As far as I can see it comes down to
adding it to spi.c or creating a new file -- or just duplicating
these 30-some lines of code to every PL.
