This type is opaque, with no accessors or setters, and there is no way
to get a hold of one except by parsing it. It's only used indirectly via
X509 functions.
The 'other' field is unused and appears to be impossible to set or
query, in either us or upstream.

The getters would leave the length uninitialized when empty, which is
dangerous if the caller does not check. Instead, always fill it in.
This opens a can of worms around whether empty alias and missing alias
are meaningfully different. Treating {NULL, 0} differently from
{non-NULL, 0} has typically caused problems. At the PKCS#12 level,
neither friendlyName, nor localKeyId are allowed to be empty, which
suggests we should not distinguish. However, X509_CERT_AUX, which is
serialized in i2d_X509_AUX, does distinguish the two states. The getters
try to, but an empty ASN1_STRING can have NULL data pointer. (Although,
when parsed, they usually do not because OpenSSL helpfully
NUL-terminates it for you.)
For now, I've just written the documentation to suggest the empty string
is the same as the missing state. I'm thinking we can make the PKCS#12
functions not bother distinguishing the two and see how it goes. I've
also gone ahead and grouped them with d2i_X509_AUX, although the rest of
the headers has not yet been grouped into sections.

I meant to grab more interesting types this round, but I missed a few
spots. We should be able to get these out of the way though.
Update-Note: Direct access of these structs should be replaced by
accessors.
