interpret-trailers: access trailer_info with new helpers

Instead of directly accessing trailer_info members, access them
indirectly through new helper functions exposed by the trailer API.

This is the first of two preparatory commits which will allow us to
use the so-called "pimpl" (pointer to implementation) idiom for the
trailer API, by making the trailer_info struct private to the trailer
implementation (and thus hidden from the API).
