This fixes a bug in ASN1_TYPE_get. Partly imported from upstream's
261ec72d58af64327214a78ca1c54b169ad93c28, though I don't believe
ASN1_TYPE_set was broken per se. There's also a lot more than in that
commit.
I've added a test to ensure we maintain the unused bits invariant
anyway, in case external code relies on it. (The invariant comes from
the pointer being NULL-initialized and from ASN1_primitive_free zeroing
*pval on free.)

A few can be made static. Move the rest of asn1_locl.h.
Update-Note: Code search says these are unused. If someone's using them,
we can reexport them.
