We've discussed that before, and held off because we weren't entirely
sure if anyone would complain that it is an API/ABI break. I think
it's quite likely that the libabigail buildfarm machines will say
it is, but is there any actual consequence?

Also, if we are going to use const in SPI, there are more parameters
besides the datatype OIDs that could stand to be const-ified, eg
the various Datum/isnull arrays.
