PROTON-2838: [Python] Treat empty list custom disposition as None
Custom dispositions would be more consistently represented as empty
lists rather than null: The only current use for descriptors is to
describe lists.
> Remove all operations using the pn_data_t structure from the frame decode path

> Key: PROTON-2838
> URL: https://issues.apache.org/jira/browse/PROTON-2838
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
>
> The pn_data_t structure is relatively inefficient and consumes quite a lot of
> memory. There are a number of places that it is used in decoding incoming
> frames whether or not that part of the frame is ever required by the
> application via the Proton API.
> We can avoid decoding the relevant protocol fields until the API requests
> them by just storing the raw protocol bytes and only creating the equivalent
> pn_data_t if it is requested by the API.
> This will also form the groundwork for a new API that allows us to creat and
> query these fields more efficiently using a new API.
