Move the parts of a capture_file used by libwireshark to a new structure.

Embed one of those structures in a capture_file, and have a struct
epan_session point to that structure rather than to a capture_file.
Pass that structure to the routines that fetch data that libwireshark
uses when dissecting.

That separates the stuff that libwireshark expects from the stuff that
it doesn't look at.
