[SECNET PATCH 2/6] rsa: Provide dict context argument in load_ctx

[Ian Jackson]

This is going to be used to make the old rsa-public and rsa-private
names honour a "hash" dictionary key in the context.

The new generic privcache and keyset machinery will use a fixed hash
so does not pass the dictionary.
