These new method signatures return and take handle objects to operate on
so we can move away from the idea of one global handle in the API. There
is also another important change and that deals with the setting of root

setter methods. This allows the library to operate more safely knowing
that paths won't change underneath it.

This addresses FS#24292. If one does the bad thing of not checking

Given that we offer no transparency into the pmpgpsig_t type, we don't

This allows several different scenarios to customize behavior:
- database

- package
- package via direct URL
- package signature via direct URL (req'd and optional)
* For databases, we need signatures from the same mirror, so structure

For a package to be loaded from any of our backends, these two fields
are always required upfront. Due to this fact, we don't need them to be
backend-specific operations and can just refer to the field directly.
Additionally, our static (and thus private) cache package accessors had
a NULL check on pkg before returning the relevant field. Eliminate this
since they only way they are ever called is via the packages attached
callback struct, which would have caused the NULL pointer dereference in
the first place.
