CORE & PROV: make export of key data leaner through callback
Exporting data from a provider owned domainparams or key is quite an
ordeal, with having to figure out what parameter keys an
implementation supports, call the export function a first time to find
out how large each parameter buffer must be, allocate the necessary
space for it, and call the export function again.
So how about letting the export function build up the key data params
and call back with that? This change implements exactly such a
mechanism.
