omapi_value_storeint().
(Arguably this is was a bug, arguably it wasn't. I do not know Ted's
original intent, but I believe it cleans up the API to allow 0 to be
set and retrieved just as any other int is.)o
(Also arguably, the other omapi_value_store*() functions should instead
be creating non-NULL omapi_value_t->value pointers when they are setting
NULL values, and then assigning NULL into the relevant union member.)
