Refactor signature result return format

I was trying to take a shortcut and not introduce a wrapper struct for
the signature results, so packed it all into alpm_sigresult_t in the
first iteration. However, this is painful when one wants to add new
fields or only return information regarding a single signature.

Refactor the type into a few components which are exposed to the end
user, and will allow a lot more future flexibility. This also exposes
more information regarding the key to the frontend than was previously
available.

The "private" void *data pointer is used by the library to store the
actual key object returned by gpgme; it is typed this way so the
frontend has no expectations of what is there, and so we don't have any
hard gpgme requirement in our public API.
